Gaseous Suppression Systems

With the multiple Gaseous Suppression System choices for protecting high risks, consideration should be taken by the fire engineer on a number of factors which will aid the selection of a suitable agent during the risk analysis phase.

DIS Fire Systems engineers have had exposure to the world’s leading gaseous fire suppression system hardware manufacturers and as such can conduct a detailed risk analysis on the proposed system taking into consideration the following:

• Suppression agent Extinguishing mechanism;
• Design concentrations and amount of extinguishing Agent needed;
• Safety for people;
• Cylinder locations and Pipe Distances to the risk area;
• Any Toxic by-products produced by the suppression agent;
• Suitability of the enclosure to maintain extinguishing agent retention;
• Suitability of the enclosure in regards to room over and under pressures produced during system discharge;
• Ozone Depletion Potential (ODP), Global Warming Potential (GWP) and Total Environmental Impact (TEWI);
• Suppression Agent holding time;
• Overall system lifetime Cost analysis.

DIS Fire Systems can offer a complete design, engineering and commissioning service on the following gaseous suppression systems:

• Inert Gas (IG-55, IG-541, Inergen) Systems;
• FM200 (HFC-227ea) Systems;
• 3M NOVEC 1230 Fire Protection Fluid;
• Carbon Dioxide (High and Low Pressure) systems;
