DescriptionDe hoog rendement warmteterugwinunit is speciaal ontworpen voor
uitgebalanceerde ventilatie met warmteterugwinning en is perfect
geschikt voor toepassing in combinatie met de Home Supply Unit.
Bij deze combinatie wordt een optimale balansventilatie gecreëerd
die zorgt voor een gezond en schoon binnenklimaat met zo min
mogelijk energieverspilling.
FunctionInsulation in buildings and homes has improved which now creates
a necessity for improved ventilation and air quality management.
Of course a good insulated home consumes less energy but also
causes less possibilities for ventilation.
By installing heat absorbing glass, modern insulation materials
and following modern building techniques, houses are constructed
in accordance with the strict Energy Performance Standard (EPN).
Due to these restrictions, humidity levels, dust particles and CO2
emissions will rise higher than the accepted values. It is now
become a necessity for constant ventilation in housing following the
balanced ventilation principle. This principle implies that extracted
and supplied air should be controlled, as specified in NEN 1087.
The HR-WTW utilizes the heat emitted from the impure, extracted air
to warm the clean external air supply. Both airflows remain strictly
separated by a cross current converter. This converter transfers 90%
of the warmth which makes the reheating of ventilated air no longer
necessary. Energy savings of approximately 400 m³ gas per year is
possible. In addition, the fresh air is filtered (filter class G3) to ensure
only clean air is supplied.
technicalspecificationsThe HR-WTW is constructed from durable, corrosion-proof and low
maintenance coated materials and is grey in colour - RAL 7035/7036.
The high quality, polished interior is thermally and acoustically
insulated. This material is self-extinguishing and complies with Fire
Classification B1, DIN4102. The HR-WTW contains our own energy
saving and noise reduction IMOFA fan.

DescriptionThe Home Supply Unit (HSU) is an indirect air treatment system.
Heat released by, for example, a central heating system, district
heating system or heat pump, is transferred to the air supply
through an intermediate medium (water) in heat coils. The main
advantages of an indirect system are comfort and low energy costs.
The HSU is easy to apply in combination with under floor heating
and solar heating along with radiators (to be installed later). This
allows you flexibility in your choices, which is not the case with
direct (gas) heating systems! Additionally, the self-regulating direct-
current fans only use half the energy used by traditional fans.
FunctionThe Home Supply Unit allows you the possibility to heat your
home efficiently and comfortably with air treatment. By applying
high efficiency heat coils, air filters, energy saving fans with the
possibility of heat recovery, you choose the optimal comfort for your
indoor climate. In combination with the Heat Recovery Unit (HR-
WTW) you can easily supply clean air whilst discharging impure air.
This allows an ultimate ventilation balance and a clean & healthy
indoor climate as well as ensuring a direct reduction of your energy
costs.
With only one initial investment, the Home Supply Unit definitely
offers you triple advantage of heating, ventilation and cooling your
home.
technicalspecificationsThe HSU is constructed from durable, corrosion-proof and low
maintenance coated materials and is grey in colour - RAL 7035/7036.
The high quality, polished interior is thermally and acoustically
insulated. This material is self-extinguishing and complies with Fire
Classification B1, DIN4102. The HSU has a built in vibration free and
noise reduction fan, which can be adjusted to different speeds.

DescriptionThe PC-600 is a fan coil unit suitable for installation in ceiling voids.
Due to the low noise level this system is frequently applied in areas
where heating, recirculation and ventilation is required. The PC-600
has pre-coated plating which enables direct installation in any area.
The minimum height of the PC-600 Unit is 285mm which ensures
easy installation in ceiling voids.
There are three circular connections situated on the outlet side,
which can be easily connected to an air duct system. These units
are normally applied for heating. The PC-600 is available with a air
distribution system, complete with flexible hose, plenums return and
distribution grilles.
FunctionWith a heating capacity of 15 kW, the PC-600 is a powerful unit. Air
is supplied by twin low noise centrifugal fans. The PC-600 suctions
air from behind the unit. The outlet side consists of three circular
connections for easy connection to an air duct system or flexible
hoses of ø200 mm. A filter can also be installed on the air supply
side.
Warm water must be supplied from an external source, such as a
boiler, distribution network or heat pump. The PC-600 is optimally
used in combination with an Air Curtain LG.
technicalspecificationsThe PC-600 is constructed from durable, corrosion-proof and low
maintenance coated panels in a light grey colour (RAL 7035). The

DescriptionThe ES-2 reduces energy costs in a very effective way and is
particularly effective in high spaces. This unit is effective in high
spaces. Transmission loss results in escaped energy, for example,
through the roof. The ES-2 forces the rising, heated air back down.
This results in a “smaller area” in which heat is suspended like a
warm blanket. The ES-2 provides a direct contribution to the energy
savings in a very efficient way.
FunctionBy pushing back the rising, heated air you directly save energy in
the lower areas. The standard fixed thermostat engages the unit
when the set temperature has been reached. The unit only functions,
therefore, when the effective temperature exists. As well as saving
energy, this regulation ensures that the system does not restart
unnecessarily and helps prevent damp. Air distribution can be
realized due to the dual regulation outlet blades.
For an optimal result, 1 ES-2 unit per 150m2 is required, at an
installation height of max. 8 meters.
technicalspecificationsThe ES-2 is constructed from durable, corrosion-proof and low
maintenance coated panels and is grey in colour - RAL 7035; other
colours on request.
Compliance as per the Standards stated in Machine Directive 89/336

teRminAlBoXes(DK),RooFeXHAustunits(tVC),RooFsupplyunits(Dtu)VENTILATION TECHNIQUE > TERMINAL BOXES WITH OR WITHOUT FAN
DescriptionBalanced air management in buildings begins to play a more
important role. The horizontally directed Terminal Boxes of the DTU/
TVC series, have been specifically designed to supply fresh air whilst
extracting impure air. These units can be supplied with a Roof Frame.
Thanks to intelligent designing, the Silencer can be fitted within the
Frame to allow the Terminal to be mounted on top. The Terminal, the
Frame and the eventual Silencer can be removed easily and quickly.
The Silencer ensures a low noise level in the outside area and in the
air duct system.
FunctionOur Terminal Boxes can be supplied with or without fan motors. You
are free in your choice of which system suits your requirements.
These units are designed for roof installation. The Roof Frame should
be installed before roofing material is placed to prevent leakage.
• DK, without fan: for air supply or air extraction, with an external
fan (VK)
• TVC with fan: suitable as an air extraction unit
• DTU with fan: suitable as an air supply unit
All types with motor fans can be supplied with a fixed maintenance
switch and/or with a separate 3-step switch or speed controller. This
makes it possible to remotely control the ventilation flow.
technicalspecificationsThe double-walled polyester casing is supplied in the colour
RAL9002. This thermally and acoustically insulated casing is
durable, resistant to all weather conditions and therefore has a long
life expectancy. The TVC’s and DTU’s are fitted with high quality
Imofa fans. These fans are mounted vibration free to ensure silent
operation. The TVC is supplied standard with a,back draught shutter
that has been specifically selected for optimal balance between flow,
air speed and sound. A protection grille is installed standard on the
exhaust end. The power cable can be connected without removal
of the fan by way of a maintenance switch or motor safe activation
switch.

DescriptionAir curtains are typically applied in store entrances, hospitals and
public buildings. By using a barrier of warm air, an air curtain
protects building entrances from energy loss, draught, dust and
insects. A properly selected and installed air curtain ensures a
conditioned climate in your store, showroom or restaurant by
preventing your heating or air conditioner from generating energy
bursts whenever visitors enter or leave. Custom made solutions are
available.
FunctionA good airflow is essential for the perfect distribution of warmth and
air in the room.
This optimal warmth distribution is attained by the powerful
centrifugal fan-motor and adjustable outlet blade. The advised height
is 2.5 metres. Warm water to be supplied by an external source, such
as a boiler, central distribution network or heat pump. The air curtain
is optimally used in combination with the air heater PC-600.
technicalspecificationsLG Air Curtains are constructed from durable, corrosion-proof and
low maintenance coated panels in the colour RAL 9016 (white). All
components, including the silent twin centrifugal fans, are securely
built in to the thermally and acoustically insulated casing. The fan
can be adjusted to different speeds
Compliance as per the Standards stated in Machine Directive 89/336
EC (attachment 2B) and the Low Voltage Directive 73/23/EEC.

DescriptionThe Unit Heater is a classic Thermo Air product. With it’s
characteristic design, this product can be found throughout Europe
and beyond. Ever since the ‘60s these indirectly fired air heaters
have be installed in storerooms, storage facilities, workshops, etc.
These air heaters are sturdy and flexible and were designed to
function continuously.
No situation is the same and that is why the Unit Heater can be
modified to your situation. All modifications and options are
available.If it’s a supply or return plenum, mixing box, room
thermostat or speed controllers, these air heaters have numerous
possibilities. Even at a later stage, this unit can be easily expanded
to become a complete air handling system. By adding a filter, mixing
section, cold water battery and perhaps a Terminal Box, you already
achieve a complete system (CLK-range).
FunctionAir direction and speed are essential for optimum heat distribution.
Air direction is controlled by the dual adjustable outlet grille. Air
speed is attained by adequate static pressure. These conditions
cannot be reached with a (noisy) axial fan. That is why a silent but
powerful centrifugal fan is used in the Unit Heater. The Unit Heater
ensures optimal heat distribution. Depending on the model, air
throw of up to 30 meters can be attained.
technicalspecificationsThe Unit Heater is constructed from durable, corrosion-proof and
low maintenance coated panels in a light grey colour (RAL 7035);
other colours are available on request. The components are built in
the high quality, polished casing which is thermally and acoustically
insulated. The silent, low speed IMOFA DD fan provides the required
pressure for a significant airflow and bridges the resistance of
an eventual filter, mixing box and/or duct system. Because the
maximum capacity is not always required, the fan can be adjusted to
different speeds.
The Unit Heater is available in 3 standard models and various
versions.

DescriptionThe UHR direct oil and/or gas fired warm air heaters are mainly applied
for heating industrial processes. These versatile units are also used for the
heating of warehouses,workshops,showrooms,factories garages, poultry
housing and the furniture industry. The UHR is used globally in spraying
cabinets and drying tunnels for luxury vehicles and yachts.
These units can be used in vertical or horizontal positions due to the
flexibility of our design. As well as 13 standard models we also supply
customised models to comply with your project and demands.
Because the UHR is oil and/or gas fired, it can be supplied with or without
a high quality burner. Where your own burner is used, we will supply
a customised securing plate following your specifications. Every UHR
can therefore be used with every type of burner. The chromium steel
combustion chambers are supplied by us with a guaranteed long life
expectancy.
FunctionThe chromium steel combustion chamber is heated by fuel from a burner.
The air is heated when the IMOFA circulates the air around the combustion
chamber. The air is then distributed through the room by the air distribution
system. For a more standard application such as setting up directly in the
room, we propose the multi-directional air distribution plenum PL4.
installatieThe technical installation of a UHR must be performed by a professional
technician, in accordance with the national and regional standards.
Always install the UHR in a sufficiently ventilated area.
technicalspecificationsThe UHR is constructed from durable, corrosion-proof and low maintenance
coated panels in a light grey colour (RAL 7035); other colours are available
on request. The components, including the chromium steel chamber and
centrifugal fan, are built in a welded frame construction. The panels are
thermally and acoustically insulated. Every unit is completely wired and
ready for use. The UHR is available in 13 standard models or customised
models following customer specifications.
Compliance as per the Standards stated in Machine Directive 89/336 EC
(attachment 2B) and the Low Voltage Directive 73/23/EEC and Directive

DescriptionBalanced air management in buildings is beginning to play a much
more important role. That is why ventilation units are used frequently in
hotels, restaurants, office buildings and shopping malls. This series is
specifically designed to supply fresh air or to extract stale air.
Due to their construction, these ventilation units can be easily placed in
an indoor environment. The units can be completely made to measure
by using the supplied fittings and adapters. This is a stylish and flexible
product, which can be adapted to any new or existing situation.
The units are produced following three construction types:
• VK cube model
• VKS low profile for ceiling void installation
• VKT with two fans for large air capacity
Depending on the construction type and model, these standard units can
displace air from 100 to 10.000 m³/h. Customised ventilation units are
available from our LBK-range.
FunctionOur ventilation units are suitable for indoor installation. Because we can
supply the units made to measure, they can be fitted to every air duct
system. They can be ideally applied in combination with our terminal
boxes type DK. One or two fans can be applied, depending on the air
volume.
Almost all types are equipped with a maintenance switch and/or an
internal 3-step switch or speed controller. This makes it possible to
remotely control the ventilation flow.
technicalspecificationsEvery ventilation unit is constructed of durable galvanised panels.
The components, including the silent centrifugal fan(s), are built
in a welded steel frame construction. The panels are thermally and
acoustically insulated. Also available in a Pentapost style, constructed of
aluminium profiles with pre-coated plating in RAL 7035. The fan is speed
controllable. The ventilation unit is available in three models and various
versions
Compliance as per the Standards stated in Machine Directive 89/336 EC

DescriptionThe air handling cabinet range can be applied in many situations
due to its compact design and low construction height. Thanks
to their modular construction they are quick and easy to produce
and can be adapted if necessary. Every CLK is dependant on the
application, air volume and external resistance and can be selected
with specific DD/DS IMOFA fans. The eventual process, whether
filtering, heating or cooling, will determine which type of CLK is
appropriate. We specify three models: the FA, LBU and FC. These
units are suitable for air volumes from 400 to 7000 m³/h. Heating,
cooling (cold water or direct expansion), mixing or filtering of the
air can all be accommadated. A complete CLK is very easy to install
thanks to our “plug and play” concept. Every unit is supplied ready
for operation, following your specific instructions.and can include
flanges for duct connections, fitted maintenance switches, speed
controllers, servomotors etc. This means a considerable saving in
the installation time.
typenThe CLK-range contains the following models and types:
Model Types Air volume (m³/h)
FA 400 600 800 ≈ 400 – 1500
LBU 7 9 10 ≈ 400 – 2400
FC 20 30 40 55 ≈ 1200 – 7000
FunctionEvery CLK uses an IMOFA DD/DS centrifugal fan. This powerful and
silent fan is the heart of the unit. Depending on your requirements,
there are CLK solutions for:
• filtering + ventilation
• filtering + heating
• filtering + heating + cooling
• filtering + cooling
• mixing + filtering + heating + cooling
Thanks to the modular construction, this unit can be adapted at a
later stage.

energysavingWith these new generation DDEC high efficiency fans you never use
more energy than necessary. This brushless direct current motor in
combination with electronic regulation utilises far less energy than
conventional motors. These constant volume fans have a high efficiency
rating of 70-80% at any speed.
Define the energy saving? See NEN 5128 - NEN 2916.
FunctionFan regulation lowers the speed and torque of the motor to the actual
pressure loss, which causes the low energy usage. In these situations
a conventional motor goes to the working point where the ventilation
curve and system curve cross each other, which results in higher energy
usage.

DescriptionThe importance of a comfortable indoor climate is often
underestimated. As producers of air handling units, we can supply
any concept of air handling and climate control equipment that is
required. Ventilation, heating, cooling, humidifying, dehumidifying
and heat recovery are some of these possibilities.
For heat recovery we utilise high efficiency cross flow heat
exchanger, twin coil systems, heat wheels and heat pipes. Also
possible is StatiqCooling, a new energy saving method of cooling
with water without a cooling machine.
Every air handling unit can be assembled according to your wishes,
without being bound to measurements. Our staff will be happy to
inform you of the possibilities.
Air volume, process, external resistance, filters, dimensions, sound,
energy use etc. will all be taken into consideration to help you make
your final choice.
To realise this, we at Thermo Air, have designed three construction
types to produce air handling units for every process.
A. Weldedframe-construction
B. pentapost-construction
C. sandwichpanel-construction
Every construction method has its own specific application areas.
As standard, we have designed a number of modules with which we
can build up our air handling units. The process determines which
construction method and module should be applied.
With these models and dimensions, we can provide you with any
type of airhandling unit you require. Given its air volume and
matching dimensions, the 30SP type is a speciality product that is
only available on request.

Constructiontypes
A.Weldedframe-constructionConstructed of a fully welded frame with single walled or
double walled insulated plating. Sendzimir galvanised plating
material is applied as standard. Available in pre-coated
colours such as RAL 9010, 9001, 7035, other colours available
on request. This construction method is frequently used for
ventilation and industrial heating processes such as spraying
cabinets or oil/gas fired air heaters.
The welded frame construction guarantees you a robust
and sturdy air handling unit. A significant advantage of this
construction type is the availability of practical modules. This
construction is suitable for indoor and outdoor installation.
B.Aluminumpentapost-constructionAluminium angle profile with single or double walled
insulated plating, with an insulation width of 20 to 50 mm. The
galvanised steel plating material is supplied standard in the
colour RAL 7035. It is also available in pre-coated panels in
the colours RAL 9010 and 9001 or customer specific colours.
This construction type has been chosen by us because of its
high quality and fast production time. It is suitable for use in
all processes for climate control. With its modular structure
the pentapost construction is of appealing design which
makes it suitable for indoor or outdoor installation.
lBK-ConCept
C.selfsupportingsandwich-constructionCompletely manufactured from self supporting sandwich
panels (with a standard width of 40 mm). This construction
type is suitable for larger air volumes and dimensions, as well
as special application ranges. The self supporting PIR/PUR
panels have a closed cel structure and are galvanised on both
sides with an RAL 7035 polyester coating. Other colours are
available on request.
All sandwich panel constructed units are single, complete
units. They are therefore applied in the larger and more
complex air handling units. Sandwich panels are available in
various panel widths.
Their robust and deluxe design can be attributed from the
UNP-profile mounting, the high inusulation degree and the
stainless steel protection profiles.

situations. Imagine the air conditioning units that are required for
large or significant events. For example, Golf Tournaments, The
Grand Prix, The Olympic Games, World Summits, World Cup or
European Cup Soccer and Film Studios. Without realizing it, you
have probably already come in contact with our Fan Coil or other
mobile units.
everythingiscustomisedThere is no standard product for these solutions: everything
is customised. After all, every customer has his own specific
requirements: special casing, various hoisting features and complete
electronic regulation. From small units that speed up during
applause in a hall, to 20 ft. sea containers that are adapted to air
handling units. These units all have one thing in common: they all
work with the “plug & play” concept. Ultimately, these units must be
operational as soon as possible.

DescriptionHeat coils are used in our own air handling products but can also be
applied in various other situations (for example built into ducting).
The special design ensures a maximum heat transfer. Standard
models are constructed of copper tubing and aluminium fins in a
galvanised steel frame. Coils can be supplied partly or completely
coated. We also supply built in electric elements (on request).
Thanks to special software, we can select the correct coils to meet
customer specifications. The possible selections are cold or warm
water, steam and of course all available cold processes such as R22,
R407C, R410A, R134A etc. Coils are also available in other materials
such as copper, aluminium, copper nickel, stainless steel and
combinations of these materials with eventual coating. Our standard
models have a fin spacing of 2.54 mm but this can be customised on
request.
typesThermo Air has the following coil types:
• standard dimensions, on stock
• customised for every situation
Because of the various range of heat coils we have in stock, in
general we deliver immediately. Customer specific heat coils are
available of request.
technicalspecificationsAll standard heat coils have a fin spacing of 2.54 mm. Every coil is
tested under water and at a pressure of 24 bar (2,4 MPa). Higher
