Aerosol fire extinguishing system

For more than ten years Pyrogen has been used by companies as the best method of switchgear fire protection. The aerosol fire extinguishing system was developed from solid rocket fuel technology and is a safe and practical alternative to halon, halocarbons, chemical powders and inert gases.

Pyrogen offers protection against fire threats for switchgear compartments, motor control centres, etc. It is an inert non-toxic solid that remains stable until electrically or thermally activated, whereupon it produces a gas-like extinguishing aerosol. The aerosol attacks the fire chemically and physically, giving virtual instant extinguishment and preventing re-ignition and, in certain instances, explosions.

The principle of the extinguishing action employed by Pyrogen is unique: a special solid chemical, when electrically or thermally ignited, produces combustion products – micron sized dry chemical particles and gases. When these dry chemical particles (mainly potassium carbonates), and gaseous mixture (mainly carbon dioxide, nitrogen and water vapour) mix together, they form a uniform fire extinguishing aerosol.

Before being released into a protected area, the hot aerosol propels itself through a unique solid coolant, which decomposes absorbing huge amounts of heat, thus ensuring flameless discharge and uniform distribution of the cool aerosol within the volume being protected.
