There are many Gaseous Fire suppression systems available on the market but how do you know which one is right for you?
At PPS we are able to offer a wide range of products and impartial advice on the system best suited to
There are many differing brands of gaseous fire suppression systems available such as FM200, NOVEC 1230, ARGOGEN, ARGONITE , INERTSAFE, & INERGEN and many more brand names. These can be split down into generally just two categories; Chemical Fire Suppression and Inert Fire Suppression Systems.
Inert Gaseous Fire Suppression Systems
These are ARGOGEN (IG55), ARGONITE, (IG55) , INERGEN (IG541) and INERTSAFE(IG541). The bracketed details are the gas compound chemical designation.
How Do Inert Gas systems work?
When discharged they work by reducing the oxygen within a room or enclosure to below 15% (normal air 21% oxygen). Below 15% most combustible materials will not burn (Class A,B and C Fires).
At this level of oxygen life is sustainable and the healthy people would not notice any adverse effects.
All of the above Gases are approved for use in normally occupied areas.
FM200 Fire Suppression.
Chemical Fire Suppression Systems
There are generally two widely available chemical agents; FM200 (HFC277ea) and NOVEC 1230.
FM200 & NOVEC 1230 Extinguish fires primarily by physical means. The molecules absorb heat so that the temperature of the flame falls to a point below which it cannot propagate and the fire is extinguished.
FM200 & NOVEC 1230 are safe for use in normally occupied areas at prescribed design concentrations.

Fire suppression systems utilise high pressure vessels which must be maintained by law. The process of test ing is achieved by hydrostatically pressurising the pressure vessel that contains the fire suppression agent.
Hydrostatic pressure testing must be carried out every 10 years. The pressure vessel (fire suppression cylinder) must be decanted, cleaned and dried. Once the contents and contaminates have been removed the fire suppression cylinder is filled with water.
As water cannot be compressed, when under pressure it allows us to verify that the cylinder is safe and fit for purpose.
