Knowledge

1 HOW DO I CORRECTLY SELECT A VOLCANO HEATER

Step one determine the temperature inside the

target room and its heat demand for heating

purposes Air heating is one of the most dynamic

methods of heating rooms allowing for the applica-

tion of temporary (eg overnight) temperature lowe-

ring in the heating room and its fast heating right

before use This allows for significant reductions in

heat consumption but does not require any heating

power surpluses to be added to the devices for quick

heating

Step two determine the location of heaters and the

necessary air stream range to guarantee the achie-

vement of suitable temperatures in the areas of the

room you are interested in Notice that the air speed

should not exceed the permissible values in human

occupancy zones or on any other sensitive areas

eg in the vicinity of industrial processes

Step three obtain information on the temperature of

the heating medium and access to the building

Step four Having all of the aforementioned data

take the VOLCANO catalogue and look for devices

which fulfill the criteria of the required air stream

and required heating power considering the possibi-

lity of work at varying outputs (first second or third

speed) Use the charts presenting air speeds in the

distance function to determine the range for each

device size Alternatively use the chart on page 19

presenting the range for limit speed of 2 fts Deter-

mine the heating power for each device speed and

for various heating medium temperatures using the

tables on pages 22-23

2 KEY ADVANTAGES OF EC MOTORS

EC motor is an electronically commutated brushless direct current motor Compared to standard motors

the efficiency of the EC motor is higher throughout their entire control range which gives significant reduction in energy costs Units equipped with these motors are charcterized by excellent durability with minimal costs associated with their operation Low noise level even with considerable rates of rotation which has a favourable influence on acustics of devices in which these motors are installed Possi-bility of connection with the BMS system allow to control all units from one place

3 HOW DOES EC MOTORS REGULA-TION WORKS

The speed of a fan equipped with an EC motor is regulated using the 0-10 V signal Optionally use a simple wall-mounted potentiometer allowing for step-less efficiency change or an advanced microprocessor controller which can carry out a series of other functions (regulation of temperature in the room weekly program ONOFF and working parameter settings anti-freeze functions etc) apart from the 3 saved efficiency thresholds

4 HOW SHOULD I GRADE THE DIAME-TERS OF THE MAIN FEED PIPELINES WHEN CONNECTING A LARGE NUMBER OF HEATERS

The diameter of the main pipeline should be adapted in such a manner that the water flow speed does not exceed 8 fts This is caused by a compromise between investment costs related to the size of the pipes used and usage costs related to the resistance of water flow in pipelines We recommend the follo-wing minimum pipeline diameters depending on the number of devices and type of heaters connected to the main according to the table on page 20

In the case of extensive installations ie when heaters are situated at least 33 ft from the heat source the diameters of pipelines should be corrected by considering lower water flow speeds

FAQ DEVICES

5 CAN I CONNECT A FEED PIPELINE TO THE UPPER HEAT EXCHANGER MANIFOLD

Yes you can although a heat exchanger powered by an upper manifold will be more difficult to vent Remember to leave sufficient space for mounting a valve actuator which should be installed on the return stub pipe

6 CAN I FEED VOLCANO VR MINI VR1 VR2 VR3 HEATERS WITH A NON-FREEZE MEDIUM

Yes you can The most frequently used non-freeze medium is a water solution of ethylene glycol The heaters mounted in VOLCANO can support up to 50 mixtures Make sure to check however if other elements of the technological heat installation (valves pump etc) are adapted to work on glycol mix To do this check the recommendations of the manufacturers of particular components used

Remember that the use of glycol mixes which are usually characterized by higher viscosity and lower thermal capacity compared to water increases the resistance of heating medium flow and reduces the heating power of the device

7 CAN THE VOLCANO VR MINIVR1 VR2 VR3 HEATER BE USED TO COOL DOWN AIR AS WELL

Yes but only when the temperature of the working medium is higher than the dew point of the cooled air since VOLCANO devices are not equipped with drip trays and we shouldnrsquot lead to the condensa-tion of humidity To switch a VOLCANO device to the cooling function connect an ice water installa-tion When there is the risk that the temperature of the working medium could fall below the dew point of the cooled air make sure to build a drip tray and install it under the device In this case the VOLCANO device will be able to work with the horizontal air outlet only The use of a VOLCANO device with vertical air outlet can result in flooding the fan motor or the space under the device since mounting a drip tray in this position of the device is impossible

VOLCANO is not equipped with a liquid trap which is why you should always reduce its work efficiency

in the cooling mode in order to eliminate the pheno-menon of drip-trapping by the air flowing through the heat exchanger

8 CAN VOLCANO VR MINI VR1 VR2 VR3 HEATERS SUPPORT HEAT PUMPS

Yes VOLCANO water heaters can cooperate with heat pumps However when selecting the size of the device take the low temperature of the heating medium into account We recommend the use of heaters with large heat exchange surfaces For this type of installation we recommend the VR3 heater equipped with a three-row heat exchanger Make sure to check VR Mini and VR2 with two-row heat exchangers as well

1 HOW DO I CORRECTLY SELECT A VOLCANO HEATER

Step one determine the temperature inside the

target room and its heat demand for heating

purposes Air heating is one of the most dynamic

methods of heating rooms allowing for the applica-

tion of temporary (eg overnight) temperature lowe-

ring in the heating room and its fast heating right

before use This allows for significant reductions in

heat consumption but does not require any heating

power surpluses to be added to the devices for quick

heating

Step two determine the location of heaters and the

necessary air stream range to guarantee the achie-

vement of suitable temperatures in the areas of the

room you are interested in Notice that the air speed

should not exceed the permissible values in human

occupancy zones or on any other sensitive areas

eg in the vicinity of industrial processes

Step three obtain information on the temperature of

the heating medium and access to the building

Step four Having all of the aforementioned data

take the VOLCANO catalogue and look for devices

which fulfill the criteria of the required air stream

and required heating power considering the possibi-

lity of work at varying outputs (first second or third

speed) Use the charts presenting air speeds in the

distance function to determine the range for each

device size Alternatively use the chart on page 19

presenting the range for limit speed of 2 fts Deter-

mine the heating power for each device speed and

for various heating medium temperatures using the

tables on pages 22-23

2 KEY ADVANTAGES OF EC MOTORS

EC motor is an electronically commutated brushless direct current motor Compared to standard motors

the efficiency of the EC motor is higher throughout their entire control range which gives significant reduction in energy costs Units equipped with these motors are charcterized by excellent durability with minimal costs associated with their operation Low noise level even with considerable rates of rotation which has a favourable influence on acustics of devices in which these motors are installed Possi-bility of connection with the BMS system allow to control all units from one place

3 HOW DOES EC MOTORS REGULA-TION WORKS

The speed of a fan equipped with an EC motor is regulated using the 0-10 V signal Optionally use a simple wall-mounted potentiometer allowing for step-less efficiency change or an advanced microprocessor controller which can carry out a series of other functions (regulation of temperature in the room weekly program ONOFF and working parameter settings anti-freeze functions etc) apart from the 3 saved efficiency thresholds

4 HOW SHOULD I GRADE THE DIAME-TERS OF THE MAIN FEED PIPELINES WHEN CONNECTING A LARGE NUMBER OF HEATERS

The diameter of the main pipeline should be adapted in such a manner that the water flow speed does not exceed 8 fts This is caused by a compromise between investment costs related to the size of the pipes used and usage costs related to the resistance of water flow in pipelines We recommend the follo-wing minimum pipeline diameters depending on the number of devices and type of heaters connected to the main according to the table on page 20

In the case of extensive installations ie when heaters are situated at least 33 ft from the heat source the diameters of pipelines should be corrected by considering lower water flow speeds

FAQ DEVICES

5 CAN I CONNECT A FEED PIPELINE TO THE UPPER HEAT EXCHANGER MANIFOLD

Yes you can although a heat exchanger powered by an upper manifold will be more difficult to vent Remember to leave sufficient space for mounting a valve actuator which should be installed on the return stub pipe

6 CAN I FEED VOLCANO VR MINI VR1 VR2 VR3 HEATERS WITH A NON-FREEZE MEDIUM

Yes you can The most frequently used non-freeze medium is a water solution of ethylene glycol The heaters mounted in VOLCANO can support up to 50 mixtures Make sure to check however if other elements of the technological heat installation (valves pump etc) are adapted to work on glycol mix To do this check the recommendations of the manufacturers of particular components used

Remember that the use of glycol mixes which are usually characterized by higher viscosity and lower thermal capacity compared to water increases the resistance of heating medium flow and reduces the heating power of the device

7 CAN THE VOLCANO VR MINIVR1 VR2 VR3 HEATER BE USED TO COOL DOWN AIR AS WELL

Yes but only when the temperature of the working medium is higher than the dew point of the cooled air since VOLCANO devices are not equipped with drip trays and we shouldnrsquot lead to the condensa-tion of humidity To switch a VOLCANO device to the cooling function connect an ice water installa-tion When there is the risk that the temperature of the working medium could fall below the dew point of the cooled air make sure to build a drip tray and install it under the device In this case the VOLCANO device will be able to work with the horizontal air outlet only The use of a VOLCANO device with vertical air outlet can result in flooding the fan motor or the space under the device since mounting a drip tray in this position of the device is impossible

VOLCANO is not equipped with a liquid trap which is why you should always reduce its work efficiency

in the cooling mode in order to eliminate the pheno-menon of drip-trapping by the air flowing through the heat exchanger

8 CAN VOLCANO VR MINI VR1 VR2 VR3 HEATERS SUPPORT HEAT PUMPS

Yes VOLCANO water heaters can cooperate with heat pumps However when selecting the size of the device take the low temperature of the heating medium into account We recommend the use of heaters with large heat exchange surfaces For this type of installation we recommend the VR3 heater equipped with a three-row heat exchanger Make sure to check VR Mini and VR2 with two-row heat exchangers as well

Knowledge

1 HOW DO I CORRECTLY SELECT A VOLCANO HEATER

Step one determine the temperature inside the

target room and its heat demand for heating

purposes Air heating is one of the most dynamic

methods of heating rooms allowing for the applica-

tion of temporary (eg overnight) temperature lowe-

ring in the heating room and its fast heating right

before use This allows for significant reductions in

heat consumption but does not require any heating

power surpluses to be added to the devices for quick

heating

Step two determine the location of heaters and the

necessary air stream range to guarantee the achie-

vement of suitable temperatures in the areas of the

room you are interested in Notice that the air speed

should not exceed the permissible values in human

occupancy zones or on any other sensitive areas

eg in the vicinity of industrial processes

Step three obtain information on the temperature of

the heating medium and access to the building

Step four Having all of the aforementioned data

take the VOLCANO catalogue and look for devices

which fulfill the criteria of the required air stream

and required heating power considering the possibi-

lity of work at varying outputs (first second or third

speed) Use the charts presenting air speeds in the

distance function to determine the range for each

device size Alternatively use the chart on page 19

presenting the range for limit speed of 2 fts Deter-

mine the heating power for each device speed and

for various heating medium temperatures using the

tables on pages 22-23

2 KEY ADVANTAGES OF EC MOTORS

EC motor is an electronically commutated brushless direct current motor Compared to standard motors

the efficiency of the EC motor is higher throughout their entire control range which gives significant reduction in energy costs Units equipped with these motors are charcterized by excellent durability with minimal costs associated with their operation Low noise level even with considerable rates of rotation which has a favourable influence on acustics of devices in which these motors are installed Possi-bility of connection with the BMS system allow to control all units from one place

3 HOW DOES EC MOTORS REGULA-TION WORKS

The speed of a fan equipped with an EC motor is regulated using the 0-10 V signal Optionally use a simple wall-mounted potentiometer allowing for step-less efficiency change or an advanced microprocessor controller which can carry out a series of other functions (regulation of temperature in the room weekly program ONOFF and working parameter settings anti-freeze functions etc) apart from the 3 saved efficiency thresholds

4 HOW SHOULD I GRADE THE DIAME-TERS OF THE MAIN FEED PIPELINES WHEN CONNECTING A LARGE NUMBER OF HEATERS

The diameter of the main pipeline should be adapted in such a manner that the water flow speed does not exceed 8 fts This is caused by a compromise between investment costs related to the size of the pipes used and usage costs related to the resistance of water flow in pipelines We recommend the follo-wing minimum pipeline diameters depending on the number of devices and type of heaters connected to the main according to the table on page 20

In the case of extensive installations ie when heaters are situated at least 33 ft from the heat source the diameters of pipelines should be corrected by considering lower water flow speeds

FAQ DEVICES

5 CAN I CONNECT A FEED PIPELINE TO THE UPPER HEAT EXCHANGER MANIFOLD

Yes you can although a heat exchanger powered by an upper manifold will be more difficult to vent Remember to leave sufficient space for mounting a valve actuator which should be installed on the return stub pipe

6 CAN I FEED VOLCANO VR MINI VR1 VR2 VR3 HEATERS WITH A NON-FREEZE MEDIUM

Yes you can The most frequently used non-freeze medium is a water solution of ethylene glycol The heaters mounted in VOLCANO can support up to 50 mixtures Make sure to check however if other elements of the technological heat installation (valves pump etc) are adapted to work on glycol mix To do this check the recommendations of the manufacturers of particular components used

Remember that the use of glycol mixes which are usually characterized by higher viscosity and lower thermal capacity compared to water increases the resistance of heating medium flow and reduces the heating power of the device

7 CAN THE VOLCANO VR MINIVR1 VR2 VR3 HEATER BE USED TO COOL DOWN AIR AS WELL

Yes but only when the temperature of the working medium is higher than the dew point of the cooled air since VOLCANO devices are not equipped with drip trays and we shouldnrsquot lead to the condensa-tion of humidity To switch a VOLCANO device to the cooling function connect an ice water installa-tion When there is the risk that the temperature of the working medium could fall below the dew point of the cooled air make sure to build a drip tray and install it under the device In this case the VOLCANO device will be able to work with the horizontal air outlet only The use of a VOLCANO device with vertical air outlet can result in flooding the fan motor or the space under the device since mounting a drip tray in this position of the device is impossible

VOLCANO is not equipped with a liquid trap which is why you should always reduce its work efficiency

in the cooling mode in order to eliminate the pheno-menon of drip-trapping by the air flowing through the heat exchanger

8 CAN VOLCANO VR MINI VR1 VR2 VR3 HEATERS SUPPORT HEAT PUMPS

Yes VOLCANO water heaters can cooperate with heat pumps However when selecting the size of the device take the low temperature of the heating medium into account We recommend the use of heaters with large heat exchange surfaces For this type of installation we recommend the VR3 heater equipped with a three-row heat exchanger Make sure to check VR Mini and VR2 with two-row heat exchangers as well

Knowledge

1 HOW DO I CORRECTLY SELECT A VOLCANO HEATER

Step one determine the temperature inside the

target room and its heat demand for heating

purposes Air heating is one of the most dynamic

methods of heating rooms allowing for the applica-

tion of temporary (eg overnight) temperature lowe-

ring in the heating room and its fast heating right

before use This allows for significant reductions in

heat consumption but does not require any heating

power surpluses to be added to the devices for quick

heating

Step two determine the location of heaters and the

necessary air stream range to guarantee the achie-

vement of suitable temperatures in the areas of the

room you are interested in Notice that the air speed

should not exceed the permissible values in human

occupancy zones or on any other sensitive areas

eg in the vicinity of industrial processes

Step three obtain information on the temperature of

the heating medium and access to the building

Step four Having all of the aforementioned data

take the VOLCANO catalogue and look for devices

which fulfill the criteria of the required air stream

and required heating power considering the possibi-

lity of work at varying outputs (first second or third

speed) Use the charts presenting air speeds in the

distance function to determine the range for each

device size Alternatively use the chart on page 19

presenting the range for limit speed of 2 fts Deter-

mine the heating power for each device speed and

for various heating medium temperatures using the

tables on pages 22-23

2 KEY ADVANTAGES OF EC MOTORS

EC motor is an electronically commutated brushless direct current motor Compared to standard motors

the efficiency of the EC motor is higher throughout their entire control range which gives significant reduction in energy costs Units equipped with these motors are charcterized by excellent durability with minimal costs associated with their operation Low noise level even with considerable rates of rotation which has a favourable influence on acustics of devices in which these motors are installed Possi-bility of connection with the BMS system allow to control all units from one place

3 HOW DOES EC MOTORS REGULA-TION WORKS

The speed of a fan equipped with an EC motor is regulated using the 0-10 V signal Optionally use a simple wall-mounted potentiometer allowing for step-less efficiency change or an advanced microprocessor controller which can carry out a series of other functions (regulation of temperature in the room weekly program ONOFF and working parameter settings anti-freeze functions etc) apart from the 3 saved efficiency thresholds

4 HOW SHOULD I GRADE THE DIAME-TERS OF THE MAIN FEED PIPELINES WHEN CONNECTING A LARGE NUMBER OF HEATERS

The diameter of the main pipeline should be adapted in such a manner that the water flow speed does not exceed 8 fts This is caused by a compromise between investment costs related to the size of the pipes used and usage costs related to the resistance of water flow in pipelines We recommend the follo-wing minimum pipeline diameters depending on the number of devices and type of heaters connected to the main according to the table on page 20

In the case of extensive installations ie when heaters are situated at least 33 ft from the heat source the diameters of pipelines should be corrected by considering lower water flow speeds

FAQ DEVICES

5 CAN I CONNECT A FEED PIPELINE TO THE UPPER HEAT EXCHANGER MANIFOLD

Yes you can although a heat exchanger powered by an upper manifold will be more difficult to vent Remember to leave sufficient space for mounting a valve actuator which should be installed on the return stub pipe

6 CAN I FEED VOLCANO VR MINI VR1 VR2 VR3 HEATERS WITH A NON-FREEZE MEDIUM

Yes you can The most frequently used non-freeze medium is a water solution of ethylene glycol The heaters mounted in VOLCANO can support up to 50 mixtures Make sure to check however if other elements of the technological heat installation (valves pump etc) are adapted to work on glycol mix To do this check the recommendations of the manufacturers of particular components used

Remember that the use of glycol mixes which are usually characterized by higher viscosity and lower thermal capacity compared to water increases the resistance of heating medium flow and reduces the heating power of the device

7 CAN THE VOLCANO VR MINIVR1 VR2 VR3 HEATER BE USED TO COOL DOWN AIR AS WELL

Yes but only when the temperature of the working medium is higher than the dew point of the cooled air since VOLCANO devices are not equipped with drip trays and we shouldnrsquot lead to the condensa-tion of humidity To switch a VOLCANO device to the cooling function connect an ice water installa-tion When there is the risk that the temperature of the working medium could fall below the dew point of the cooled air make sure to build a drip tray and install it under the device In this case the VOLCANO device will be able to work with the horizontal air outlet only The use of a VOLCANO device with vertical air outlet can result in flooding the fan motor or the space under the device since mounting a drip tray in this position of the device is impossible

VOLCANO is not equipped with a liquid trap which is why you should always reduce its work efficiency

in the cooling mode in order to eliminate the pheno-menon of drip-trapping by the air flowing through the heat exchanger

8 CAN VOLCANO VR MINI VR1 VR2 VR3 HEATERS SUPPORT HEAT PUMPS

Yes VOLCANO water heaters can cooperate with heat pumps However when selecting the size of the device take the low temperature of the heating medium into account We recommend the use of heaters with large heat exchange surfaces For this type of installation we recommend the VR3 heater equipped with a three-row heat exchanger Make sure to check VR Mini and VR2 with two-row heat exchangers as well

1 HOW DO I CORRECTLY SELECT A VOLCANO HEATER

Step one determine the temperature inside the

target room and its heat demand for heating

purposes Air heating is one of the most dynamic

methods of heating rooms allowing for the applica-

tion of temporary (eg overnight) temperature lowe-

ring in the heating room and its fast heating right

before use This allows for significant reductions in

heat consumption but does not require any heating

power surpluses to be added to the devices for quick

heating

Step two determine the location of heaters and the

necessary air stream range to guarantee the achie-

vement of suitable temperatures in the areas of the

room you are interested in Notice that the air speed

should not exceed the permissible values in human

occupancy zones or on any other sensitive areas

eg in the vicinity of industrial processes

Step three obtain information on the temperature of

the heating medium and access to the building

Step four Having all of the aforementioned data

take the VOLCANO catalogue and look for devices

which fulfill the criteria of the required air stream

and required heating power considering the possibi-

lity of work at varying outputs (first second or third

speed) Use the charts presenting air speeds in the

distance function to determine the range for each

device size Alternatively use the chart on page 19

presenting the range for limit speed of 2 fts Deter-

mine the heating power for each device speed and

for various heating medium temperatures using the

tables on pages 22-23

2 KEY ADVANTAGES OF EC MOTORS

EC motor is an electronically commutated brushless direct current motor Compared to standard motors

the efficiency of the EC motor is higher throughout their entire control range which gives significant reduction in energy costs Units equipped with these motors are charcterized by excellent durability with minimal costs associated with their operation Low noise level even with considerable rates of rotation which has a favourable influence on acustics of devices in which these motors are installed Possi-bility of connection with the BMS system allow to control all units from one place

3 HOW DOES EC MOTORS REGULA-TION WORKS

The speed of a fan equipped with an EC motor is regulated using the 0-10 V signal Optionally use a simple wall-mounted potentiometer allowing for step-less efficiency change or an advanced microprocessor controller which can carry out a series of other functions (regulation of temperature in the room weekly program ONOFF and working parameter settings anti-freeze functions etc) apart from the 3 saved efficiency thresholds

4 HOW SHOULD I GRADE THE DIAME-TERS OF THE MAIN FEED PIPELINES WHEN CONNECTING A LARGE NUMBER OF HEATERS

The diameter of the main pipeline should be adapted in such a manner that the water flow speed does not exceed 8 fts This is caused by a compromise between investment costs related to the size of the pipes used and usage costs related to the resistance of water flow in pipelines We recommend the follo-wing minimum pipeline diameters depending on the number of devices and type of heaters connected to the main according to the table on page 20

In the case of extensive installations ie when heaters are situated at least 33 ft from the heat source the diameters of pipelines should be corrected by considering lower water flow speeds

FAQ DEVICES

5 CAN I CONNECT A FEED PIPELINE TO THE UPPER HEAT EXCHANGER MANIFOLD

Yes you can although a heat exchanger powered by an upper manifold will be more difficult to vent Remember to leave sufficient space for mounting a valve actuator which should be installed on the return stub pipe

6 CAN I FEED VOLCANO VR MINI VR1 VR2 VR3 HEATERS WITH A NON-FREEZE MEDIUM

Yes you can The most frequently used non-freeze medium is a water solution of ethylene glycol The heaters mounted in VOLCANO can support up to 50 mixtures Make sure to check however if other elements of the technological heat installation (valves pump etc) are adapted to work on glycol mix To do this check the recommendations of the manufacturers of particular components used

Remember that the use of glycol mixes which are usually characterized by higher viscosity and lower thermal capacity compared to water increases the resistance of heating medium flow and reduces the heating power of the device

7 CAN THE VOLCANO VR MINIVR1 VR2 VR3 HEATER BE USED TO COOL DOWN AIR AS WELL

Yes but only when the temperature of the working medium is higher than the dew point of the cooled air since VOLCANO devices are not equipped with drip trays and we shouldnrsquot lead to the condensa-tion of humidity To switch a VOLCANO device to the cooling function connect an ice water installa-tion When there is the risk that the temperature of the working medium could fall below the dew point of the cooled air make sure to build a drip tray and install it under the device In this case the VOLCANO device will be able to work with the horizontal air outlet only The use of a VOLCANO device with vertical air outlet can result in flooding the fan motor or the space under the device since mounting a drip tray in this position of the device is impossible

VOLCANO is not equipped with a liquid trap which is why you should always reduce its work efficiency

in the cooling mode in order to eliminate the pheno-menon of drip-trapping by the air flowing through the heat exchanger

8 CAN VOLCANO VR MINI VR1 VR2 VR3 HEATERS SUPPORT HEAT PUMPS

Yes VOLCANO water heaters can cooperate with heat pumps However when selecting the size of the device take the low temperature of the heating medium into account We recommend the use of heaters with large heat exchange surfaces For this type of installation we recommend the VR3 heater equipped with a three-row heat exchanger Make sure to check VR Mini and VR2 with two-row heat exchangers as well

Knowledge

1 HOW DO I CORRECTLY SELECT A VOLCANO HEATER

Step one determine the temperature inside the

target room and its heat demand for heating

purposes Air heating is one of the most dynamic

methods of heating rooms allowing for the applica-

tion of temporary (eg overnight) temperature lowe-

ring in the heating room and its fast heating right

before use This allows for significant reductions in

heat consumption but does not require any heating

power surpluses to be added to the devices for quick

heating

Step two determine the location of heaters and the

necessary air stream range to guarantee the achie-

vement of suitable temperatures in the areas of the

room you are interested in Notice that the air speed

should not exceed the permissible values in human

occupancy zones or on any other sensitive areas

eg in the vicinity of industrial processes

Step three obtain information on the temperature of

the heating medium and access to the building

Step four Having all of the aforementioned data

take the VOLCANO catalogue and look for devices

which fulfill the criteria of the required air stream

and required heating power considering the possibi-

lity of work at varying outputs (first second or third

speed) Use the charts presenting air speeds in the

distance function to determine the range for each

device size Alternatively use the chart on page 19

presenting the range for limit speed of 2 fts Deter-

mine the heating power for each device speed and

for various heating medium temperatures using the

tables on pages 22-23

2 KEY ADVANTAGES OF EC MOTORS

EC motor is an electronically commutated brushless direct current motor Compared to standard motors

the efficiency of the EC motor is higher throughout their entire control range which gives significant reduction in energy costs Units equipped with these motors are charcterized by excellent durability with minimal costs associated with their operation Low noise level even with considerable rates of rotation which has a favourable influence on acustics of devices in which these motors are installed Possi-bility of connection with the BMS system allow to control all units from one place

3 HOW DOES EC MOTORS REGULA-TION WORKS

The speed of a fan equipped with an EC motor is regulated using the 0-10 V signal Optionally use a simple wall-mounted potentiometer allowing for step-less efficiency change or an advanced microprocessor controller which can carry out a series of other functions (regulation of temperature in the room weekly program ONOFF and working parameter settings anti-freeze functions etc) apart from the 3 saved efficiency thresholds

4 HOW SHOULD I GRADE THE DIAME-TERS OF THE MAIN FEED PIPELINES WHEN CONNECTING A LARGE NUMBER OF HEATERS

The diameter of the main pipeline should be adapted in such a manner that the water flow speed does not exceed 8 fts This is caused by a compromise between investment costs related to the size of the pipes used and usage costs related to the resistance of water flow in pipelines We recommend the follo-wing minimum pipeline diameters depending on the number of devices and type of heaters connected to the main according to the table on page 20

In the case of extensive installations ie when heaters are situated at least 33 ft from the heat source the diameters of pipelines should be corrected by considering lower water flow speeds

FAQ DEVICES

5 CAN I CONNECT A FEED PIPELINE TO THE UPPER HEAT EXCHANGER MANIFOLD

Yes you can although a heat exchanger powered by an upper manifold will be more difficult to vent Remember to leave sufficient space for mounting a valve actuator which should be installed on the return stub pipe

6 CAN I FEED VOLCANO VR MINI VR1 VR2 VR3 HEATERS WITH A NON-FREEZE MEDIUM

Yes you can The most frequently used non-freeze medium is a water solution of ethylene glycol The heaters mounted in VOLCANO can support up to 50 mixtures Make sure to check however if other elements of the technological heat installation (valves pump etc) are adapted to work on glycol mix To do this check the recommendations of the manufacturers of particular components used

Remember that the use of glycol mixes which are usually characterized by higher viscosity and lower thermal capacity compared to water increases the resistance of heating medium flow and reduces the heating power of the device

7 CAN THE VOLCANO VR MINIVR1 VR2 VR3 HEATER BE USED TO COOL DOWN AIR AS WELL

Yes but only when the temperature of the working medium is higher than the dew point of the cooled air since VOLCANO devices are not equipped with drip trays and we shouldnrsquot lead to the condensa-tion of humidity To switch a VOLCANO device to the cooling function connect an ice water installa-tion When there is the risk that the temperature of the working medium could fall below the dew point of the cooled air make sure to build a drip tray and install it under the device In this case the VOLCANO device will be able to work with the horizontal air outlet only The use of a VOLCANO device with vertical air outlet can result in flooding the fan motor or the space under the device since mounting a drip tray in this position of the device is impossible

VOLCANO is not equipped with a liquid trap which is why you should always reduce its work efficiency

in the cooling mode in order to eliminate the pheno-menon of drip-trapping by the air flowing through the heat exchanger

8 CAN VOLCANO VR MINI VR1 VR2 VR3 HEATERS SUPPORT HEAT PUMPS

Yes VOLCANO water heaters can cooperate with heat pumps However when selecting the size of the device take the low temperature of the heating medium into account We recommend the use of heaters with large heat exchange surfaces For this type of installation we recommend the VR3 heater equipped with a three-row heat exchanger Make sure to check VR Mini and VR2 with two-row heat exchangers as well

Knowledge

1 HOW DO I CORRECTLY SELECT A VOLCANO HEATER

Step one determine the temperature inside the

target room and its heat demand for heating

purposes Air heating is one of the most dynamic

methods of heating rooms allowing for the applica-

tion of temporary (eg overnight) temperature lowe-

ring in the heating room and its fast heating right

before use This allows for significant reductions in

heat consumption but does not require any heating

power surpluses to be added to the devices for quick

heating

Step two determine the location of heaters and the

necessary air stream range to guarantee the achie-

vement of suitable temperatures in the areas of the

room you are interested in Notice that the air speed

should not exceed the permissible values in human

occupancy zones or on any other sensitive areas

eg in the vicinity of industrial processes

Step three obtain information on the temperature of

the heating medium and access to the building

Step four Having all of the aforementioned data

take the VOLCANO catalogue and look for devices

which fulfill the criteria of the required air stream

and required heating power considering the possibi-

lity of work at varying outputs (first second or third

speed) Use the charts presenting air speeds in the

distance function to determine the range for each

device size Alternatively use the chart on page 19

presenting the range for limit speed of 2 fts Deter-

mine the heating power for each device speed and

for various heating medium temperatures using the

tables on pages 22-23

2 KEY ADVANTAGES OF EC MOTORS

EC motor is an electronically commutated brushless direct current motor Compared to standard motors

the efficiency of the EC motor is higher throughout their entire control range which gives significant reduction in energy costs Units equipped with these motors are charcterized by excellent durability with minimal costs associated with their operation Low noise level even with considerable rates of rotation which has a favourable influence on acustics of devices in which these motors are installed Possi-bility of connection with the BMS system allow to control all units from one place

3 HOW DOES EC MOTORS REGULA-TION WORKS

The speed of a fan equipped with an EC motor is regulated using the 0-10 V signal Optionally use a simple wall-mounted potentiometer allowing for step-less efficiency change or an advanced microprocessor controller which can carry out a series of other functions (regulation of temperature in the room weekly program ONOFF and working parameter settings anti-freeze functions etc) apart from the 3 saved efficiency thresholds

4 HOW SHOULD I GRADE THE DIAME-TERS OF THE MAIN FEED PIPELINES WHEN CONNECTING A LARGE NUMBER OF HEATERS

The diameter of the main pipeline should be adapted in such a manner that the water flow speed does not exceed 8 fts This is caused by a compromise between investment costs related to the size of the pipes used and usage costs related to the resistance of water flow in pipelines We recommend the follo-wing minimum pipeline diameters depending on the number of devices and type of heaters connected to the main according to the table on page 20

In the case of extensive installations ie when heaters are situated at least 33 ft from the heat source the diameters of pipelines should be corrected by considering lower water flow speeds

FAQ DEVICES

5 CAN I CONNECT A FEED PIPELINE TO THE UPPER HEAT EXCHANGER MANIFOLD

Yes you can although a heat exchanger powered by an upper manifold will be more difficult to vent Remember to leave sufficient space for mounting a valve actuator which should be installed on the return stub pipe

6 CAN I FEED VOLCANO VR MINI VR1 VR2 VR3 HEATERS WITH A NON-FREEZE MEDIUM

Yes you can The most frequently used non-freeze medium is a water solution of ethylene glycol The heaters mounted in VOLCANO can support up to 50 mixtures Make sure to check however if other elements of the technological heat installation (valves pump etc) are adapted to work on glycol mix To do this check the recommendations of the manufacturers of particular components used

Remember that the use of glycol mixes which are usually characterized by higher viscosity and lower thermal capacity compared to water increases the resistance of heating medium flow and reduces the heating power of the device

7 CAN THE VOLCANO VR MINIVR1 VR2 VR3 HEATER BE USED TO COOL DOWN AIR AS WELL

Yes but only when the temperature of the working medium is higher than the dew point of the cooled air since VOLCANO devices are not equipped with drip trays and we shouldnrsquot lead to the condensa-tion of humidity To switch a VOLCANO device to the cooling function connect an ice water installa-tion When there is the risk that the temperature of the working medium could fall below the dew point of the cooled air make sure to build a drip tray and install it under the device In this case the VOLCANO device will be able to work with the horizontal air outlet only The use of a VOLCANO device with vertical air outlet can result in flooding the fan motor or the space under the device since mounting a drip tray in this position of the device is impossible

VOLCANO is not equipped with a liquid trap which is why you should always reduce its work efficiency

in the cooling mode in order to eliminate the pheno-menon of drip-trapping by the air flowing through the heat exchanger

8 CAN VOLCANO VR MINI VR1 VR2 VR3 HEATERS SUPPORT HEAT PUMPS

Yes VOLCANO water heaters can cooperate with heat pumps However when selecting the size of the device take the low temperature of the heating medium into account We recommend the use of heaters with large heat exchange surfaces For this type of installation we recommend the VR3 heater equipped with a three-row heat exchanger Make sure to check VR Mini and VR2 with two-row heat exchangers as well

1 HOW DO I CORRECTLY SELECT A VOLCANO HEATER

Step one determine the temperature inside the

target room and its heat demand for heating

purposes Air heating is one of the most dynamic

methods of heating rooms allowing for the applica-

tion of temporary (eg overnight) temperature lowe-

ring in the heating room and its fast heating right

before use This allows for significant reductions in

heat consumption but does not require any heating

power surpluses to be added to the devices for quick

heating

Step two determine the location of heaters and the

necessary air stream range to guarantee the achie-

vement of suitable temperatures in the areas of the

room you are interested in Notice that the air speed

should not exceed the permissible values in human

occupancy zones or on any other sensitive areas

eg in the vicinity of industrial processes

Step three obtain information on the temperature of

the heating medium and access to the building

Step four Having all of the aforementioned data

take the VOLCANO catalogue and look for devices

which fulfill the criteria of the required air stream

and required heating power considering the possibi-

lity of work at varying outputs (first second or third

speed) Use the charts presenting air speeds in the

2 KEY ADVANTAGES OF EC MOTORS

EC motor is an electronically commutated brushless direct current motor Compared to standard motors

the efficiency of the EC motor is higher throughout their entire control range which gives significant reduction in energy costs Units equipped with these motors are charcterized by excellent durability with minimal costs associated with their operation Low noise level even with considerable rates of rotation which has a favourable influence on acustics of devices in which these motors are installed Possi-bility of connection with the BMS system allow to control all units from one place

3 HOW DOES EC MOTORS REGULA-TION WORKS

The speed of a fan equipped with an EC motor is regulated using the 0-10 V signal Optionally use a simple wall-mounted potentiometer allowing for step-less efficiency change or an advanced microprocessor controller which can carry out a series of other functions (regulation of temperature in the room weekly program ONOFF and working parameter settings anti-freeze functions etc) apart from the 3 saved efficiency thresholds

4 HOW SHOULD I GRADE THE DIAME-TERS OF THE MAIN FEED PIPELINES WHEN CONNECTING A LARGE NUMBER OF HEATERS

The diameter of the main pipeline should be adapted in such a manner that the water flow speed does not exceed 8 fts This is caused by a compromise between investment costs related to the size of the pipes used and usage costs related to the resistance of water flow in pipelines We recommend the follo-wing minimum pipeline diameters depending on the number of devices and type of heaters connected to the main according to the table on page 20

In the case of extensive installations ie when heaters are situated at least 33 ft from the heat source the diameters of pipelines should be corrected by considering lower water flow speeds

FAQ DEVICES

5 CAN I CONNECT A FEED PIPELINE TO THE UPPER HEAT EXCHANGER MANIFOLD

Yes you can although a heat exchanger powered by an upper manifold will be more difficult to vent Remember to leave sufficient space for mounting a valve actuator which should be installed on the return stub pipe

6 CAN I FEED VOLCANO VR MINI VR1 VR2 VR3 HEATERS WITH A NON-FREEZE MEDIUM

Yes you can The most frequently used non-freeze medium is a water solution of ethylene glycol The heaters mounted in VOLCANO can support up to 50 mixtures Make sure to check however if other elements of the technological heat installation (valves pump etc) are adapted to work on glycol mix To do this check the recommendations of the manufacturers of particular components used

Remember that the use of glycol mixes which are usually characterized by higher viscosity and lower thermal capacity compared to water increases the resistance of heating medium flow and reduces the heating power of the device

7 CAN THE VOLCANO VR MINIVR1 VR2 VR3 HEATER BE USED TO COOL DOWN AIR AS WELL

Yes but only when the temperature of the working medium is higher than the dew point of the cooled air since VOLCANO devices are not equipped with drip trays and we shouldnrsquot lead to the condensa-tion of humidity To switch a VOLCANO device to the cooling function connect an ice water installa-tion When there is the risk that the temperature of the working medium could fall below the dew point of the cooled air make sure to build a drip tray and install it under the device In this case the VOLCANO device will be able to work with the horizontal air outlet only The use of a VOLCANO device with vertical air outlet can result in flooding the fan motor or the space under the device since mounting a drip tray in this position of the device is impossible

VOLCANO is not equipped with a liquid trap which is why you should always reduce its work efficiency

in the cooling mode in order to eliminate the pheno-menon of drip-trapping by the air flowing through the heat exchanger

8 CAN VOLCANO VR MINI VR1 VR2 VR3 HEATERS SUPPORT HEAT PUMPS

Yes VOLCANO water heaters can cooperate with heat pumps However when selecting the size of the device take the low temperature of the heating medium into account We recommend the use of heaters with large heat exchange surfaces For this type of installation we recommend the VR3 heater equipped with a three-row heat exchanger Make sure to check VR Mini and VR2 with two-row heat exchangers as well

Knowledge

1 HOW DO I CORRECTLY SELECT A VOLCANO HEATER

Step one determine the temperature inside the

target room and its heat demand for heating

purposes Air heating is one of the most dynamic

methods of heating rooms allowing for the applica-

tion of temporary (eg overnight) temperature lowe-

ring in the heating room and its fast heating right

before use This allows for significant reductions in

heat consumption but does not require any heating

power surpluses to be added to the devices for quick

heating

Step two determine the location of heaters and the

necessary air stream range to guarantee the achie-

vement of suitable temperatures in the areas of the

room you are interested in Notice that the air speed

should not exceed the permissible values in human

occupancy zones or on any other sensitive areas

eg in the vicinity of industrial processes

Step three obtain information on the temperature of

the heating medium and access to the building

Step four Having all of the aforementioned data

take the VOLCANO catalogue and look for devices

which fulfill the criteria of the required air stream

and required heating power considering the possibi-

lity of work at varying outputs (first second or third

speed) Use the charts presenting air speeds in the

distance function to determine the range for each

device size Alternatively use the chart on page 19

presenting the range for limit speed of 2 fts Deter-

mine the heating power for each device speed and

for various heating medium temperatures using the

tables on pages 22-23

2 KEY ADVANTAGES OF EC MOTORS

EC motor is an electronically commutated brushless direct current motor Compared to standard motors

the efficiency of the EC motor is higher throughout their entire control range which gives significant reduction in energy costs Units equipped with these motors are charcterized by excellent durability with minimal costs associated with their operation Low noise level even with considerable rates of rotation which has a favourable influence on acustics of devices in which these motors are installed Possi-bility of connection with the BMS system allow to control all units from one place

3 HOW DOES EC MOTORS REGULA-TION WORKS

The speed of a fan equipped with an EC motor is regulated using the 0-10 V signal Optionally use a simple wall-mounted potentiometer allowing for step-less efficiency change or an advanced microprocessor controller which can carry out a series of other functions (regulation of temperature in the room weekly program ONOFF and working parameter settings anti-freeze functions etc) apart from the 3 saved efficiency thresholds

4 HOW SHOULD I GRADE THE DIAME-TERS OF THE MAIN FEED PIPELINES WHEN CONNECTING A LARGE NUMBER OF HEATERS

The diameter of the main pipeline should be adapted in such a manner that the water flow speed does not exceed 8 fts This is caused by a compromise between investment costs related to the size of the pipes used and usage costs related to the resistance of water flow in pipelines We recommend the follo-wing minimum pipeline diameters depending on the number of devices and type of heaters connected to the main according to the table on page 20

In the case of extensive installations ie when heaters are situated at least 33 ft from the heat source the diameters of pipelines should be corrected by considering lower water flow speeds

FAQ DEVICES

5 CAN I CONNECT A FEED PIPELINE TO THE UPPER HEAT EXCHANGER MANIFOLD

Yes you can although a heat exchanger powered by an upper manifold will be more difficult to vent Remember to leave sufficient space for mounting a valve actuator which should be installed on the return stub pipe

6 CAN I FEED VOLCANO VR MINI VR1 VR2 VR3 HEATERS WITH A NON-FREEZE MEDIUM

Yes you can The most frequently used non-freeze medium is a water solution of ethylene glycol The heaters mounted in VOLCANO can support up to 50 mixtures Make sure to check however if other elements of the technological heat installation (valves pump etc) are adapted to work on glycol mix To do this check the recommendations of the manufacturers of particular components used

Remember that the use of glycol mixes which are usually characterized by higher viscosity and lower thermal capacity compared to water increases the resistance of heating medium flow and reduces the heating power of the device

7 CAN THE VOLCANO VR MINIVR1 VR2 VR3 HEATER BE USED TO COOL DOWN AIR AS WELL

Yes but only when the temperature of the working medium is higher than the dew point of the cooled air since VOLCANO devices are not equipped with drip trays and we shouldnrsquot lead to the condensa-tion of humidity To switch a VOLCANO device to the cooling function connect an ice water installa-tion When there is the risk that the temperature of the working medium could fall below the dew point of the cooled air make sure to build a drip tray and install it under the device In this case the VOLCANO device will be able to work with the horizontal air outlet only The use of a VOLCANO device with vertical air outlet can result in flooding the fan motor or the space under the device since mounting a drip tray in this position of the device is impossible

VOLCANO is not equipped with a liquid trap which is why you should always reduce its work efficiency

in the cooling mode in order to eliminate the pheno-menon of drip-trapping by the air flowing through the heat exchanger

8 CAN VOLCANO VR MINI VR1 VR2 VR3 HEATERS SUPPORT HEAT PUMPS

Yes VOLCANO water heaters can cooperate with heat pumps However when selecting the size of the device take the low temperature of the heating medium into account We recommend the use of heaters with large heat exchange surfaces For this type of installation we recommend the VR3 heater equipped with a three-row heat exchanger Make sure to check VR Mini and VR2 with two-row heat exchangers as well

Knowledge

1 HOW DO I CORRECTLY SELECT A VOLCANO HEATER

Step one determine the temperature inside the

target room and its heat demand for heating

purposes Air heating is one of the most dynamic

methods of heating rooms allowing for the applica-

tion of temporary (eg overnight) temperature lowe-

ring in the heating room and its fast heating right

before use This allows for significant reductions in

heat consumption but does not require any heating

power surpluses to be added to the devices for quick

heating

Step two determine the location of heaters and the

necessary air stream range to guarantee the achie-

vement of suitable temperatures in the areas of the

room you are interested in Notice that the air speed

should not exceed the permissible values in human

occupancy zones or on any other sensitive areas

eg in the vicinity of industrial processes

Step three obtain information on the temperature of

the heating medium and access to the building

Step four Having all of the aforementioned data

take the VOLCANO catalogue and look for devices

which fulfill the criteria of the required air stream

and required heating power considering the possibi-

lity of work at varying outputs (first second or third

speed) Use the charts presenting air speeds in the

distance function to determine the range for each

device size Alternatively use the chart on page 19

presenting the range for limit speed of 2 fts Deter-

mine the heating power for each device speed and

for various heating medium temperatures using the

tables on pages 22-23

2 KEY ADVANTAGES OF EC MOTORS

EC motor is an electronically commutated brushless direct current motor Compared to standard motors

the efficiency of the EC motor is higher throughout their entire control range which gives significant reduction in energy costs Units equipped with these motors are charcterized by excellent durability with minimal costs associated with their operation Low noise level even with considerable rates of rotation which has a favourable influence on acustics of devices in which these motors are installed Possi-bility of connection with the BMS system allow to control all units from one place

3 HOW DOES EC MOTORS REGULA-TION WORKS

The speed of a fan equipped with an EC motor is regulated using the 0-10 V signal Optionally use a simple wall-mounted potentiometer allowing for step-less efficiency change or an advanced microprocessor controller which can carry out a series of other functions (regulation of temperature in the room weekly program ONOFF and working parameter settings anti-freeze functions etc) apart from the 3 saved efficiency thresholds

4 HOW SHOULD I GRADE THE DIAME-TERS OF THE MAIN FEED PIPELINES WHEN CONNECTING A LARGE NUMBER OF HEATERS

The diameter of the main pipeline should be adapted in such a manner that the water flow speed does not exceed 8 fts This is caused by a compromise between investment costs related to the size of the pipes used and usage costs related to the resistance of water flow in pipelines We recommend the follo-wing minimum pipeline diameters depending on the number of devices and type of heaters connected to the main according to the table on page 20

In the case of extensive installations ie when heaters are situated at least 33 ft from the heat source the diameters of pipelines should be corrected by considering lower water flow speeds

FAQ DEVICES

5 CAN I CONNECT A FEED PIPELINE TO THE UPPER HEAT EXCHANGER MANIFOLD

Yes you can although a heat exchanger powered by an upper manifold will be more difficult to vent Remember to leave sufficient space for mounting a valve actuator which should be installed on the return stub pipe

6 CAN I FEED VOLCANO VR MINI VR1 VR2 VR3 HEATERS WITH A NON-FREEZE MEDIUM

Yes you can The most frequently used non-freeze medium is a water solution of ethylene glycol The heaters mounted in VOLCANO can support up to 50 mixtures Make sure to check however if other elements of the technological heat installation (valves pump etc) are adapted to work on glycol mix To do this check the recommendations of the manufacturers of particular components used

Remember that the use of glycol mixes which are usually characterized by higher viscosity and lower thermal capacity compared to water increases the resistance of heating medium flow and reduces the heating power of the device

7 CAN THE VOLCANO VR MINIVR1 VR2 VR3 HEATER BE USED TO COOL DOWN AIR AS WELL

Yes but only when the temperature of the working medium is higher than the dew point of the cooled air since VOLCANO devices are not equipped with drip trays and we shouldnrsquot lead to the condensa-tion of humidity To switch a VOLCANO device to the cooling function connect an ice water installa-tion When there is the risk that the temperature of the working medium could fall below the dew point of the cooled air make sure to build a drip tray and install it under the device In this case the VOLCANO device will be able to work with the horizontal air outlet only The use of a VOLCANO device with vertical air outlet can result in flooding the fan motor or the space under the device since mounting a drip tray in this position of the device is impossible

VOLCANO is not equipped with a liquid trap which is why you should always reduce its work efficiency

in the cooling mode in order to eliminate the pheno-menon of drip-trapping by the air flowing through the heat exchanger

8 CAN VOLCANO VR MINI VR1 VR2 VR3 HEATERS SUPPORT HEAT PUMPS

Yes VOLCANO water heaters can cooperate with heat pumps However when selecting the size of the device take the low temperature of the heating medium into account We recommend the use of heaters with large heat exchange surfaces For this type of installation we recommend the VR3 heater equipped with a three-row heat exchanger Make sure to check VR Mini and VR2 with two-row heat exchangers as well

1 HOW DO I CORRECTLY SELECT A VOLCANO HEATER

Step one determine the temperature inside the

target room and its heat demand for heating

purposes Air heating is one of the most dynamic

methods of heating rooms allowing for the applica-

tion of temporary (eg overnight) temperature lowe-

ring in the heating room and its fast heating right

before use This allows for significant reductions in

heat consumption but does not require any heating

power surpluses to be added to the devices for quick

heating

Step two determine the location of heaters and the

necessary air stream range to guarantee the achie-

vement of suitable temperatures in the areas of the

room you are interested in Notice that the air speed

should not exceed the permissible values in human

occupancy zones or on any other sensitive areas

eg in the vicinity of industrial processes

Step three obtain information on the temperature of

the heating medium and access to the building

Step four Having all of the aforementioned data

take the VOLCANO catalogue and look for devices

which fulfill the criteria of the required air stream

and required heating power considering the possibi-

lity of work at varying outputs (first second or third

speed) Use the charts presenting air speeds in the

distance function to determine the range for each

device size Alternatively use the chart on page 19

presenting the range for limit speed of 2 fts Deter-

mine the heating power for each device speed and

for various heating medium temperatures using the

tables on pages 22-23

2 KEY ADVANTAGES OF EC MOTORS

EC motor is an electronically commutated brushless direct current motor Compared to standard motors

the efficiency of the EC motor is higher throughout their entire control range which gives significant reduction in energy costs Units equipped with these motors are charcterized by excellent durability with minimal costs associated with their operation Low noise level even with considerable rates of rotation which has a favourable influence on acustics of devices in which these motors are installed Possi-bility of connection with the BMS system allow to control all units from one place

3 HOW DOES EC MOTORS REGULA-TION WORKS

The speed of a fan equipped with an EC motor is regulated using the 0-10 V signal Optionally use a simple wall-mounted potentiometer allowing for step-less efficiency change or an advanced microprocessor controller which can carry out a series of other functions (regulation of temperature in the room weekly program ONOFF and working parameter settings anti-freeze functions etc) apart from the 3 saved efficiency thresholds

4 HOW SHOULD I GRADE THE DIAME-TERS OF THE MAIN FEED PIPELINES WHEN CONNECTING A LARGE NUMBER OF HEATERS

The diameter of the main pipeline should be adapted in such a manner that the water flow speed does not exceed 8 fts This is caused by a compromise between investment costs related to the size of the pipes used and usage costs related to the resistance of water flow in pipelines We recommend the follo-wing minimum pipeline diameters depending on the number of devices and type of heaters connected to the main according to the table on page 20

In the case of extensive installations ie when heaters are situated at least 33 ft from the heat source the diameters of pipelines should be corrected by considering lower water flow speeds

FAQ DEVICES

5 CAN I CONNECT A FEED PIPELINE TO THE UPPER HEAT EXCHANGER MANIFOLD

Yes you can although a heat exchanger powered by an upper manifold will be more difficult to vent Remember to leave sufficient space for mounting a valve actuator which should be installed on the return stub pipe

6 CAN I FEED VOLCANO VR MINI VR1 VR2 VR3 HEATERS WITH A NON-FREEZE MEDIUM

Yes you can The most frequently used non-freeze medium is a water solution of ethylene glycol The heaters mounted in VOLCANO can support up to 50 mixtures Make sure to check however if other elements of the technological heat installation (valves pump etc) are adapted to work on glycol mix To do this check the recommendations of the manufacturers of particular components used

Remember that the use of glycol mixes which are usually characterized by higher viscosity and lower thermal capacity compared to water increases the resistance of heating medium flow and reduces the heating power of the device

7 CAN THE VOLCANO VR MINIVR1 VR2 VR3 HEATER BE USED TO COOL DOWN AIR AS WELL

Yes but only when the temperature of the working medium is higher than the dew point of the cooled air since VOLCANO devices are not equipped with drip trays and we shouldnrsquot lead to the condensa-tion of humidity To switch a VOLCANO device to the cooling function connect an ice water installa-tion When there is the risk that the temperature of the working medium could fall below the dew point of the cooled air make sure to build a drip tray and install it under the device In this case the VOLCANO device will be able to work with the horizontal air outlet only The use of a VOLCANO device with vertical air outlet can result in flooding the fan motor or the space under the device since mounting a drip tray in this position of the device is impossible

VOLCANO is not equipped with a liquid trap which is why you should always reduce its work efficiency

in the cooling mode in order to eliminate the pheno-menon of drip-trapping by the air flowing through the heat exchanger

8 CAN VOLCANO VR MINI VR1 VR2 VR3 HEATERS SUPPORT HEAT PUMPS

Yes VOLCANO water heaters can cooperate with heat pumps However when selecting the size of the device take the low temperature of the heating medium into account We recommend the use of heaters with large heat exchange surfaces For this type of installation we recommend the VR3 heater equipped with a three-row heat exchanger Make sure to check VR Mini and VR2 with two-row heat exchangers as well

1 HOW DO I CORRECTLY SELECT A VOLCANO HEATER

Step one determine the temperature inside the

target room and its heat demand for heating

purposes Air heating is one of the most dynamic

methods of heating rooms allowing for the applica-

tion of temporary (eg overnight) temperature lowe-

ring in the heating room and its fast heating right

before use This allows for significant reductions in

heat consumption but does not require any heating

power surpluses to be added to the devices for quick

heating

Step two determine the location of heaters and the

necessary air stream range to guarantee the achie-

vement of suitable temperatures in the areas of the

room you are interested in Notice that the air speed

should not exceed the permissible values in human

occupancy zones or on any other sensitive areas

eg in the vicinity of industrial processes

Step three obtain information on the temperature of

the heating medium and access to the building

Step four Having all of the aforementioned data

take the VOLCANO catalogue and look for devices

which fulfill the criteria of the required air stream

and required heating power considering the possibi-

lity of work at varying outputs (first second or third

speed) Use the charts presenting air speeds in the

distance function to determine the range for each

device size Alternatively use the chart on page 19

presenting the range for limit speed of 2 fts Deter-

mine the heating power for each device speed and

for various heating medium temperatures using the

tables on pages 22-23

2 KEY ADVANTAGES OF EC MOTORS

EC motor is an electronically commutated brushless direct current motor Compared to standard motors

the efficiency of the EC motor is higher throughout their entire control range which gives significant reduction in energy costs Units equipped with these motors are charcterized by excellent durability with minimal costs associated with their operation Low noise level even with considerable rates of rotation which has a favourable influence on acustics of devices in which these motors are installed Possi-bility of connection with the BMS system allow to control all units from one place

3 HOW DOES EC MOTORS REGULA-TION WORKS

The speed of a fan equipped with an EC motor is regulated using the 0-10 V signal Optionally use a simple wall-mounted potentiometer allowing for step-less efficiency change or an advanced microprocessor controller which can carry out a series of other functions (regulation of temperature in the room weekly program ONOFF and working parameter settings anti-freeze functions etc) apart from the 3 saved efficiency thresholds

4 HOW SHOULD I GRADE THE DIAME-TERS OF THE MAIN FEED PIPELINES WHEN CONNECTING A LARGE NUMBER OF HEATERS

The diameter of the main pipeline should be adapted in such a manner that the water flow speed does not exceed 8 fts This is caused by a compromise between investment costs related to the size of the pipes used and usage costs related to the resistance of water flow in pipelines We recommend the follo-wing minimum pipeline diameters depending on the number of devices and type of heaters connected to the main according to the table on page 20

In the case of extensive installations ie when heaters are situated at least 33 ft from the heat source the diameters of pipelines should be corrected by considering lower water flow speeds

FAQ DEVICES

5 CAN I CONNECT A FEED PIPELINE TO THE UPPER HEAT EXCHANGER MANIFOLD

Yes you can although a heat exchanger powered by an upper manifold will be more difficult to vent Remember to leave sufficient space for mounting a valve actuator which should be installed on the return stub pipe

6 CAN I FEED VOLCANO VR MINI VR1 VR2 VR3 HEATERS WITH A NON-FREEZE MEDIUM

Yes you can The most frequently used non-freeze medium is a water solution of ethylene glycol The heaters mounted in VOLCANO can support up to 50 mixtures Make sure to check however if other elements of the technological heat installation (valves pump etc) are adapted to work on glycol mix To do this check the recommendations of the manufacturers of particular components used

Remember that the use of glycol mixes which are usually characterized by higher viscosity and lower thermal capacity compared to water increases the resistance of heating medium flow and reduces the heating power of the device

7 CAN THE VOLCANO VR MINIVR1 VR2 VR3 HEATER BE USED TO COOL DOWN AIR AS WELL

Yes but only when the temperature of the working medium is higher than the dew point of the cooled air since VOLCANO devices are not equipped with drip trays and we shouldnrsquot lead to the condensa-tion of humidity To switch a VOLCANO device to the cooling function connect an ice water installa-tion When there is the risk that the temperature of the working medium could fall below the dew point of the cooled air make sure to build a drip tray and install it under the device In this case the VOLCANO device will be able to work with the horizontal air outlet only The use of a VOLCANO device with vertical air outlet can result in flooding the fan motor or the space under the device since mounting a drip tray in this position of the device is impossible

VOLCANO is not equipped with a liquid trap which is why you should always reduce its work efficiency

in the cooling mode in order to eliminate the pheno-menon of drip-trapping by the air flowing through the heat exchanger

8 CAN VOLCANO VR MINI VR1 VR2 VR3 HEATERS SUPPORT HEAT PUMPS

Yes VOLCANO water heaters can cooperate with heat pumps However when selecting the size of the device take the low temperature of the heating medium into account We recommend the use of heaters with large heat exchange surfaces For this type of installation we recommend the VR3 heater equipped with a three-row heat exchanger Make sure to check VR Mini and VR2 with two-row heat exchangers as well
