PYROGEN... Developed from solid rocket fuel technology, it's the worlds' first commercially available aerosol fire extinguishing system.
Off-shore, commercial and military aircraft, data rooms, machinery and automation equipment, plant machinery, electrical cabinets, military vehicles, shipping and marine.
Designed as safe and practical alternative to halon, halo carbons, chemical powders and inert gases, PYROGEN is available from stock in a wide range of canister sizes. It is an inert non-toxic solid that remains stable until electrically or thermally activated. Upon generation, the aerosol behaves like a gas, attacking the fire chemically and physically, giving virtual instant extinguishment and preventing re-ignition, and in certain instances, explosions.
The principle of extinguishing action employed by PYROGEN is unique - a special solid chemical, which when electrically or thermally ignited, produces combustion by-products - micron size dry chemical particles and gases. Dry chemical particles (mainly potassium carbonates), and gaseous mixture (mainly carbon dioxide, nitrogen and water vapour), mix together into a uniform fire extinguishing aerosol. Before being released into a protected area, the hot aerosol propels itself through a patented solid chemical coolant, which decomposes absorbing huge amounts of heat, thus ensuring flame less discharge and uniform distribution of the cool aerosol within the area, the high rate of aerosol discharge ensures a tremendous knockdown 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. Homogeneous distribution is achieved in a matter of seconds, while long holding times help to prevent fire re-ignition.
Primarily due to the high obscuration, it is designed for use in normally unoccupied areas such as machinery and engine spaces, control cabinets and storage areas. Inadvertent exposure to the aerosol should be avoided using normal precautions such as warning signals, pre-discharge alarm and post-discharge warning and venting. Accidental exposure to aerosol should be limited to 5 minutes.
As obscuration may impede the egress of personnel, hold off devices may be required for large areas or those with internal obstructions. Further details on safe application, installation, operation and recommissioning of PYROGEN systems is given in the design manual and a manufacturers safety data sheet is available upon request.
