HFC-227ea (FM-200) is a compressed gas which is stored as a liquid and dispensed into the hazard area as a clear, odourless and electrically non-conductive vapour that does not obscure vision. It leaves no residue and, at the correct design concentration, is suitable for the protection of occupied areas.

HFC-227ea is a very effective fire extinguishing agent that can be used to protect a wide range of applications. It is suitable for use on class A (solid combustibles) and class B (flammable liquids) fires, including risks with live electrical equipment.

Suppression systems

The extinguishing gas works primarily by physically absorbing heat so that the temperature of the flame falls to a point below which it cannot spread. It does not displace oxygen which makes it safe for use in occupied areas.

HFC-227ea has a zero ozone-depletion potential and a short atmospheric lifetime and is therefore considered as an environmentally acceptable extinguishing agent.
