Typical applications of inert gas fire suppression systems

Inert gas suppression systems use argon and nitrogen gases and their mixtures as an extinguishing agent and are based in the principle of reducing the oxygen concentration inside the protected hazard. The oxygen concentration is minimized by the application of inert gas until it reaches a level where combustion is no longer supported. Each system is designed so as to decrease oxygen to a specific level. When discharged, inert gas is quickly and uniformly distributed within the enclosure, achieving design concentration in 60 seconds.

Argon and nitrogen it is naturally present in the atmosphere, therefore its green-house effect is nil and its ozone layer depletion potential is zero. It is chemically inert, non-conductive, colourless, odourless and flavourless. inert gas is non-corrosive and may be used at normal temperatures with such materials as nickel, steel, stainless steel, copper, brass, bronze and plastics.

These gases will never be re-classified as “hazardous waste” nor require special inspection procedures under the EU’s “F” Gas Regulations.

Inert gas fire suppression systems are the safe, natural way to extinguish a fire. Because of its unique patented valve assembly, inert gas agent enters the protected room within the industry required 60 seconds but at a steady flow rate — preventing destructive turbulence from occurring. This constant flow rate allows for the use of small-diameter, low pressure (and less expensive) piping from the inert gas container all the way to the nozzle. And, the necessary venting area is much smaller — reducing installation costs by as much as 60% on venting hardware.

Inert gas systems, previously available in 150 and 200 bar cylinders, are now available with 300 bar gaseous fire protection technology. That means more inert gas in each cylinder, reducing the number of cylinders and accessory equipment necessary. In addition to a sizable reduction in system cost, fewer cylinders translates into an inert gas fire protection solution that takes less valuable space.
