Difficult Area Protection

PYROGEN... Developed from solid rocket fuel technology, it's the worlds' first commercially available aerosol fire extinguishing system.

Uses include:

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.


  • Environmentally friendly - certified as having zero ozone depleteing potential (ODP) and zero global warming potential (GWP). It is officially listed by the US Environmental Protection Authority under it Halon replacement Significant New Alternatives Program (SNAP)
  • No pressurised cylinders or pipe work - PYROGEN canisters are self contained, zero pressure units, aswell as being light and safe to transport, they require no additional pipes, nozzles or distribution equipment. They cannot leak, burst or deteriorate, and can be stored for up to 10 years without maintenance.
  • Tests and Certification - tested by Scientific Service Laboratories (Australia) and is undergoing certification worldwide. For the latest approval listings and test data please contact us.
  • Compact and Weight Saving - PYROGEN canisters can provide the smallest and lightest fire extinguishing system currently available. With space requirements up to 1/40th of inert gases, and weight penalties of often only 10% of competing systems, PYROGEN in many cases is the only practical Halon replacement.
  • Simple to Install & Recommission - canisters are electrically (or automatically thermally activated). Simple wiring and plug in connectors can be reduce installation times to a third or less. If discharged, new canisters maybe reinstallaed in minutes* affording minimal downtime and eliminate potentially potentially hazardous periods of non-active fire suppression.
  • Low Toxicity - Unlike some flouorinated gases, PYROGEN produces no aggressive acids such as Hydrogen Fluoride upon contact with hot surfaces, PYROGEN produces no chloride or bromide and does not deplete oxygen to suppress the fire.
  • Cost Effective - with minimal space and weight requirements, simple installation, zero maintenance and up to 10 years service life, PYROGEN is arguably the most cost effective Halon alternative available. 
    * Providing all and any necessary safety checks and inspections have been completed.

Health and Safety Statement

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.
