How it works

Pyrogen BahrainUnlike conventional fire extinguishing systems, Pyrogen is an inert non-toxic solid that remains stable until electrically or thermally activated, where upon it produces a gas-like extinguishing aerosol. The aerosol attacks the fire chemically and physically, giving virtual instant extinguishment & preventing re-ignition, and in certain instances, explosions. For many applications, Pyrogen is the only practical alternative to Halon.

The special solid chemical within the cannister, when electrically or thermally ignited, produces combustion products - micron sized dry particles, (mainly potassium carbonates), and gaseous mixture, (mainly carbon dioxide, nitrogen and water vapour), mix together into a uniform fire extinguishing aerosol.

The hot aerosol propels itself through a unique solid chemical coolant, which decomposes absorbing huge amounts of heat, thus ensuring flameless discharge and uniform distribution of the cool aerosol within the area.

The high rate of aerosol discharge ensures a tremendous knock down effect. Micron size aerosol particles exhibit gas-like three-dimensional qualities that allow the agent to rapidly distribute throughout enclosure and reach even the most concealed and shielded locations. Homogenous distribution is achieved in a matter of seconds, while long holding times all help to prevent fire re-ignition.
