A revolution in
fire suppression technology
It really is rocket science
It really is rocket science
A revolution is taking place in Fire Suppression. Developed from solid
rocket fuel technology, Pyrogen is the worlds’ first commercially available
Aerosol Fire Extinguishing System. Designed as a safe & practical
alternative to Halon, Halocarbons, Chemical Powders and Inert Gases
Pyrogen is available from stock in a wide range of canister sizes. 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.

Health & Safety Statement
Primarily due to the high obscuration, PYROGEN is designed for use in normally unoccupied areas such as data rooms, 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 the
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.
