Gas Suppression Systems

Inert Gas Systems

Inert Gas systems offer the most flexible approach to fire suppression, and are best suited to large applications. 

The properties of the extinguishing agents (IG-01, IG-100, IG-55 and IG-541) together with the high storage pressures of the cylinders (typically 200 & 300 bar), allow multiple enclosures to be protected by a single set of inert gas cylinders.


Directional valves are used to control the release of the inert gas system to the correct enclosure, which can often be located up to 100-metres away from the cylinder set.

Carbon Dioxide Systems

CO2 systems are best suited to the protection of unmanned enclosures, where the safety of personnel is not a concern.

Whilst other gaseous systems require a high standard of "room integrity" to retain the extinguishant within the protected enclosure. CO2 systems can protect equipment that is not enclosed by a permanent boundary, or where it is not possible to completely seal the protected enclosure.

Novec Gas Systems

3M™ Novec™ 1230 Fire Protection Fluid is by far the safest gaseous based fire extinguishing agent on the market today, with high safety margins between the design concentration and the No Observable Adverse Effect Level (NOAEL).

Novec 1230 fluid has zero ozone depletion potential (ODP) and a global warming potential (GWP) of just one. The atmospheric lifetime is between three and five days making HYGOOD SAPPHIRE an ideal solution without compromising the environment.

FM200 Systems

FM200 Systems are by far the most popular gaseous fire suppression system on the market today.

Whilst limitations with the hydraulic calculation of systems means that design of large systems (e.g. data centres) becomes particularly cumbersome. FM200 systems are ideal for the protection of small to mid-sized enclosures such as Telecoms Facilities, Computer Rooms, Archive Spaces etc.
