Gaseous systems basics

When you need: full homogenous 3-dimensional effect, non residual, no electric

conductivity direct or indirect, penetration into cabinets or installations.

When you have: Shielded objects, hardly accessible areas, deep seated or concealed

fires, high ceilings, sensitive equipment where water would cause same damage like fire.

Typical applications: All kind of electric risks like IT areas, Switchgear , Communication,

Control rooms, Cable tunnels, Data Center, Archives, electric cabinets and many more

No other agent can give you this characteristics !

GWP= Global Warming Potential

� The GWP is shown off as CO2 equivalents, 1 kg of FM-

200 contributes so much to the global warming like

3220 kg of CO2 !

� The height of the GWP Value depend´s on the

atmospheric lifetime, FM-200 stays for about 40 years in

the atmosphere HFC-23 for over 260 years !

� The most common used HFKW for extinguishing

purpose are:

� FM-200/FE-227ea/HFC-227ea = GWP 3220

� FE-13/Trigon/HFC-23 = GWP 14800

� FE-25/Ecaro25/HFC-125=GWP 3500

� This means by mass, in case of release a CO2 equivalent

emission of approx. “2,2 tons” / m³ with HFC-227ea

� and approx. “7,7 tons” with HFC-23, per m³.

NFPA 2001: 5.4.2.4* The minimum design concentration for a

Class A surface-fire hazard shall be determined by the greater of

the following:

(1) The extinguishing concentration, as determined in 5.4.2.2,

times a safety factor of 1.2

(2) Equal to the minimum extinguishing concentration for heptane

as determined from 5.4.2.1

NFPA 2001: 5.4.2.2* The flame extinguishing concentration for

Class A fuels shall be determined

by test as part of a listing program. As a minimum, the listing

program shall conform to UL 2127 or

UL 2166 or equivalent. The Class A fuels test on plastic sheets was

accomplished with Class A MEC for both agents.

HFC227ea:

Our Class B MEC: 6,9Vol%

Our Class A MEC: 5,4Vol% x1,2= 6,48Vol%

6,9 > 6,48Vol% so we use 7Vol% for class A surface-fire / Class A

fuels

FK-5-1-12:

Our Class B MEC: 4,5Vol%

Our Class A MEC: 3,3Vol% x1,2=4,0Vol%

4,5 > 4,0 Vol% so we use 4,5% for class A surface / Class A fuels

Minimum design concentration HFC-227ea / FK-5-1-12


ISO14520: 7.5.1.3 The extinguishing concentration for Class A

surface fires shall be the greater of the values determined

by the wood crib and polymeric sheet fire tests described in

Annex C. The minimum design concentration for

Class A fires shall be the extinguishing concentration increased by

a safety factor of 1,3. For non-cellulosic

Class A fuels, higher design concentrations may be required..

HFC227ea:

Class A MEC: 6,1Vol% x1,3=7,9Vol%

NFPA 2001: 5.4.2.3 The minimum design concentration for a Class

B fuel hazard shall be

the extinguishing concentration, as determined in 5.4.2.1, times a

safety factor of 1.3.

HFC227ea:

Our Class B MEC: 6,9Vol% x 1,3 = 8,97Vol% = 9Vol%

Novec 1230:

Our Class B MEC: 4,5Vol% x 1,3 = 5,9Vol%



ISO14520: 7.5.1.2 The minimum Class B design concentration for

each extinguishant shall be a demonstrated

extinguishing concentration for each Class B fuel plus a safety

factor of 1,3. The extinguishing concentration

used shall be that demonstrated by the cup burner test, carried

out in accordance with the method set out in

Annex B, that has been verified with the heptane pan tests

detailed in C.5.2. For hazards involving multiple

fuels, the value for the fuel requiring the greatest design

concentration shall be used. The extinguishing

concentration shall be taken as the cup burner value or the

heptane pan test value (see Annex C), whichever is greater.

HFC227ea:

Our Class B MEC: 6,9Vol% x 1,3 = 9Vol%

Novec 1230:

Our Class B MEC: 4,5Vol% x 1,3 = 5,9Vol%

© Viking

NFPA 2001: 5.4.2.5 The minimum design concentration for a Class

C hazard shall be the extinguishing concentration, as determined

in 5.4.2.2, times a safety factor of 1.35.

HFC227ea:

Class A MEC: 5,4 x 1,35 = 7,3 Vol%

Novec 1230:

Class A MEC 3,3 x 1,35 = 4,5Vol%

5.4.2.5.1 The minimum design concentration for spaces

containing energized electrical hazards supplied at greater than

480 volts that remain powered during and after discharge shall be

determined by testing, as necessary, and a hazard analysis.

Attention for certain electric risks !

For the reason using higher design concentrations please refer to

NFPA 2001 -2012 A.5.4.2.2 (Fire extinguishment tests for

(noncellulosic) Class A Surface Fires.)

Where any of the following conditions exists, higher extinguishing

concentrations might be required:

(1) Cable bundles greater than 4 in. (100 mm) in diameter

(2) Cable trays with a fill density greater than 20 percent of the

tray cross section

(3) Horizontal or vertical stacks of cable trays less than 10 in. (250

mm) apart

(4) Equipment energized during the extinguishment period where

the collective power consumption exceeds 5 kW.



ISO14520 7.5.1.3: CAUTION — It is recognized that the wood crib

and .polymeric sheet Class A fire tests may not adequately

indicate extinguishing concentrations suitable for the protection

of certain plastic fuel hazards (e.g. electrical and electronic type

hazards involving grouped power or data cables such as

computer and control room under-floor voids, telecommunication

facilities, etc.). An extinguishing concentration not less than that

determined in accordance with 7.5.1.3, or not less than of that

determined from the heptane fire test described in C.6.2,

whichever is the greater, should be used under certain conditions.

These conditions may include:

1) cable bundles greater than in diameter;

2) cable trays with a fill density greater than of the tray cross-

section;

3) horizontal or vertical stacks of cable trays (closer than );

4) equipment energized during the extinguishment period where

the collective power consumption exceeds 5kW.

If polymeric sheet fire test data are not available, an extinguishing

concentration of that determined from the heptane fire test shall

be used.

HFC227ea:

Class B MEC: 6,1 x 1,3 = 9 Vol% * 0,95 = 8,5Vol%

Novec 1230:

Class B MEC: 4,5 x 1,3 = 5,9 Vol% * 0,95 = 5,6Vol%

Structural needs

� Rooms protected by clean agents should be

sealed against their environment, to avoid

combustible gases from outside.

� This tightness ensures the 10min soak period.

� A tight room gives us a higher A/C efficiency

� If the room is sealed, it‘s integrity could be

damaged during flooding without pressure

venting.

� When using clean agents, damaging can be

avoided by controlled air and pressure flaps.

History of working pressures

� CO2 was always working with 60bar

� Inertgases are working also with 60bar after the pressure reducer or 30-40bar whenconstant flow valve is equipped.

� Halon 1301 has a vapor pressure of ca.200psi at 21°C in order to increase the capability 160psi nitrogen where added in the US giving 360psi(24,8bar), in Europe system where created with 42bar (610psi) in order to work on longer distances. (CO2 hardware was used)

� FM-200 has a vapor pressure of 4bar, the difference to Halon was substituted byNitrogen in the US, in Europe systems where created with 42bar (Halon hardware)

� Novec 1230 has a vapor pressure of 0,4bar, the difference to FM-200 was substitutedby Nitrogen. Also 42bar systems where created by using FM-200 42bar Hardware

� Due to the lazyness of Novec 1230 to leave the cylinder, having more pressure isadvantageous. Welded cylinders are now available with 500psi (34,5bar) what is themaximum for a welded cylinder according DOT seamless with 50bar (725psi).

� Nitrogen is the propellant and will be flooded after the agent

� Example of Nitrogen amount:

� 1 cylinder 180l, 25bar, fill 186,3kg Novec 1230

� 186,3kg Novec 1230 = 115,3l Novec 1230 (dens. 1,616kg/l)

� 1 cylinder 32l, 25bar, fill 18,6kg Novec 1230

� 18,6kg Novec 1230 = 11,5l Novec 1230

� 180l - 115,3l Novec 1230 + 32l - 11,5l Novec = 85,2l Nitrogen x 25bar = 2130l expanded Nitrogen

� 1 cylinder: 180l, 50bar, fill 197,8kg + 4,6kg heel, Novec 1230

� 202,4kg Novec 1230 = 125,2l Novec 1230 (dens. 1,616kg/l)

� 180l minus 125,2l Novec = 54,8l Nitrogen x 42bar = 2301l expanded Nitrogen (50bar = 2740l)

� A higher working pressure acts with a similar amount of Nitrogen, itjust compress it to less volume.

� Nozzle pressure will be reduced by smaller pipes in case of higherworking pressure.

� Final nozzle pressures are at same level

25/34,5 bar

Is the higher working pressure a threat for the room integrity

APPROVALS

Recommended approvals for hardware

� Why do we need a system approval ?

� All components have to show their reliability in long term tests

� The complete systems has to show its performance

� The performance must be predicted by a software

� The software is the most crucial part of a system.

� With FM/UL listings it is strictly linked with the system

� VdS Software is a kind of open source, always aks for VdS approval of the calculated system.

� Attention has to paid to the cylinders, here additional certificates are required, e.g. DOT, TPED,

� Offshore application often requires different approval than onshore

� Pay special attention to CE in Europe

Principle

� Centralized agent storage

� Hazards are served via valves

� In case of alarm the corresponding valve will open and release the agent to the area

� Wich kind of systems you know working like that ?

� Sprinkler

� Foam

� Gas


© Viking

Main characteristics

� Single zone: The agent quantity is calculated to flood the protected zone one time, with reserve two times

� Independent from other rooms

� More rooms = linear increase of investment

� Space cosuming

� Multizone: The agent quantity is calculated for the biggest of several volumes, the necessary quantity is released in case of alarm and flooded via a selectional valve into the area, a 100% reserve is often used.

� First come first serve

� Limited investment in agent and cylinders

� Occupies only small space


© Viking

� Minimax&Viking approved as first and so faronly company a multizone system utilizingNovec 1230 according FM/UL approvalguidelines.

� This contains, cylinder and all hardware forsingle zone systems

� Selectorvalves and related componentes

� Software to calculate selectorvalve manifold.

� Up 15 rooms can be connected to onecylinder bank.

Golden rules multizone

� Minimum room agent requirement per room should be 150kg to be connected to Multizone system, otherwise single system is more economic


� Saving: 1 cylinder with accessories and agent

� Additional: 1 Selector valve with accessories

© Viking


� Ideal relation of rooms connected to one system is 4:1

� The background is a limit of the hydraulic calculation called “agent in pipe”

� This shall be not more than f.e. 85% (our software)

� If first pipes are to big (necessary for bigger areas) nitrogen will go ahead of agent and agent supply will be not sufficient to build up concentration

� Pressure drops to much in Selector valve manifold

� Example:

� Biggest room requires 1000kg, and therefore manifold and selector valve manifold is 4”

� Smallest requires 150kg, this will be flooded into 4” manifolds

� If rooms vary more than 4:1 we may consider one system for big rooms and one for small rooms.


1000kg

150kg

Nitrogen

� Maximum agent for biggest hazard ca. 1300kg, if bigger rooms need to be protected consider either slave battery or separate system

Examples for savings

Single systems: 21cylinder – 2632kg

Multizone with reserve: 6 + 6cylinders = 12 cylinders 748kg+748kg = 1496kg

� All systems have a common principle

� Different working pressures available

� Higher working pressure provides more flexibility

� Higher working pressure is no threat to room integrity

� Higher working pressure saves space and hardware

� Working with Multizone saves cost

� If applying Multizone it is crucial that the software calculates the selector valve manifold

� For Halon substitution more pressure is necessary
