Gaseous Fire Suppression Systems

---

There are many Gaseous Fire suppression systems available
on the market but how do you know which one is right for you?

At Aspect Fire Solutions we are able to offer a wide range of
products and impartial advice on the system best suited to
your needs.

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.

Pressure Relief Damping

A consideration with any Gas Suppression system is pressure relief damping.
pressure relief damping

As a gas suppression agent is discharged into
an enclosure it creates a positive pressure within
the enclosure. Should there be insufficient
natural leakage within the enclosure structural
damage due to the over pressurisation of the
room could occur.

At Aspect, we can calculate the correct size of
pressure relief damper required for each
enclosure and are also able to offer an installation
service for pressure relief dampers.
