With the continuous concerns regarding environmental impact and international treaties such as the Montreal Protocol and the Kyoto Protocol, have been put into place regulating gases that can be used, amongst other industries, in fire suppression applications, hence reducing ozone depletion as well as having no greenhouse effect potential.

Inert gases are recognized for being 100% eco-friendly being naturally available in the air that we breathe. They are not toxic for humans , they do not release dangerous substances when in contact with fire, visibility is not impaired, there’s no fogging and do not release residues post discharge.



  • Easily refilled locally.
  • Electrically non conductive.
  • High pressure filling, allows for delocalized cylinder location from the protected risk.
  • Can be configured to protect various risks with only one system.
  • Visibility is not reduced upon discharge.
  • Ability to reach hidden fires.

Fire suppression mechanism
Cutting off or diluting the source of oxygen, reducing its concentration to below 15%, extinguishing the fire in 60 seconds.

Methods of application
Since fire is suppressed by reducing the concentration of oxygen in the air, achieved by increasing the concentration of the inert gas discharged, these gases can only be applied by total flooding, requiring minimum air tightness in the room.

Typical hazards protected
Including but not limited to Data Centres, server rooms and general IT facilities, telecommunications, industrial risks, libraries, archives, museums, art galleries, flammable liquids storage, transformer rooms.



Depending on the risk(s) being protected, various configurations can be designed:

  • Modular cylinder (one cylinder set up)
  • Bank system (multiple cylinder set up)
  • If several hazards have to be protected, one bank system can be used along with selector valves.

All 4 inert gases are available at storage pressures of 200 and 300 bar in either 80 litre or 140 litre cylinders, the working pressure is reduced to 60 bar when entering piping network.

  • IG-01, Argon
  • IG-100,Nitrogen
  • IG-55, 50% Nitrogen + 50% Argon
  • IG-541,50% Nitrogen + 42% Argon + 8% CO2

Check out its key features:

  • Compact valve technology; allows using the standard cylinder transportation safety cap, avoids using special caps and adapters.
  • Direct release circuit; outlet connection to activate the slave cylinders from the master valve, eliminating the pilot cylinder and relief screw (except selector valve configuration).
  • Maintenance at its safest; all components may be assembled and disassembled whilst under pressure, this includes: pressure gauge, pneumatic release, manual release and solenoid valve.
  • Discharge-free commissioning system, whilst performing system functional testing during commissioning, the release circuit can be disconnected from the valves avoiding any accidental discharge and allow easy testing.
  • Standing strong and secure; stand alone or wall mounted brackets with several configurations available, adapting the system to the room space.
  • Flexible and resistant; all release and discharge hoses take into account the best balance between flexibility and durability, allowing easy installation and strength to withstand the pass of time.
  • Spare-parts free; upon discharge or during maintenance, no rupture disks, nor special components must be replaced. Reducing down-time and lowering warehousing costs.
  • Differential pressure actuation allows using the same pressure from the cylinder to maintain the valve closed, reducing dramatically leakage problems even with high temperature fluctuations.
  • Optimized standardization of systems, common components between systems reduces quantities needed hence saving on warehousing costs and allowing fast delivery to clients locally.



Our engineers are prepared to design the inert fire suppression projects according to the required standards:

  • NFPA 2001: 2015
  • EN15004: 2008
  • APSAD R13
