The Aerosol Fire Supression System - Pyrogen

1 PyrogenThe AerosolFire Supression SystemPyroshieldSpecialistFire ProtectionNow availableexclusively from off-shoreA revolution is taking place in fire Suppression. Developed from solidrocket fuel technology, Pyrogen is the world's first commercially availableAerosol fire Extinguishing System . Designed as a safe & practicalalternative to Halon, Halocarbons, Chemical Powders and Inert GasesPyrogen is available from stock in a wide range of canister sizes. Pyrogenis an inert non-toxic solid that remains stable until electrically or thermallyactivated, where upon it produces a gas-like extinguishing Aerosol . Theaerosol attacks the fire chemically and physically, giving virtual instantextinguishment & preventing re-ignition, and in certain instances,explosions. For many applications Pyrogen is the only practicalalternative to installed close to the potential hazardSome of the sizes availableWhen electrically or thermally ignited, Pyrogengenerates the fire extinguishing aerosolEasily reinstalled within minutesSpecialist fire ProtectionPyroshieldSuppliers of The PyrogenAerosol Supression System 3 times more effective than a maximum* design concentration of 100g per m3 Pyrogen exhibits equal or better extinguishingproperties than Halon 1301 at 330g per m volume),as certified by Scientific Services has the lowest extinguishing concentrationamongst commercially available agents.

It is officially listed by the USEnvironmental Protection Authority under itsHalon replacement Significant New AlternativesProgram (SNAP). Pyrogen Canisters are self contained, zero pressureunits. As well as being light & safe to transport, theyrequire no additional pipes, nozzles or distributionequipment. They cannot leak, burst or deteriorate,and can be stored for up to 10 years has been tested by LPC, Scientific ServiceLaboratories (Australia) and is undergoing furthercertification worldwide.

Simple wiring & plug inconnectors can reduce installation times to a 1/3rdor less. If discharged, new canisters may bereinstalled in minutes* affording minimal downtimeand eliminate potentially hazardous periods ofnon-active fire suppression .*Providing all and any necessary safety checks & inspections have been some Halon alternatives, Pyrogen producesno aggressive acids such as Hydrogen Fluorideupon contact with hot surfaces. Pyrogen producesno chlorine or bromide and does not depleteoxygen to suppress the minimal space & weight requirements, simpleinstallation, zero maintenance and up to 10 yearsservice life, Pyrogen is arguably the most costeffective Halon alternative available.

5 Dry chemical particles, (mainlypotassium carbonates), and gaseous mixture, (mainly carbondioxide, nitrogen and water vapour), mix together into a uniformfire extinguishing Aerosol . Before being released into a protectedarea, the hot Aerosol propels itself through a unique solidchemical coolant, which decomposes absorbing huge amountsof heat, thus ensuring flameless discharge and uniform distributionof the cool Aerosol within the high rate of Aerosol discharge ensures a tremendous knockdowneffect. Micron size Aerosol particles exhibit gas-like threedimensionalqualities that allow the agent to rapidly distributethroughout enclosure and reach even the most concealed andshielded locations.

Inadvertent exposure to the Aerosol should be avoided using normal precautions such as warning signals, pre-discharge alarmand post-discharge warning and venting. Accidental exposure to Aerosol should be limited to 5 obscuration may impede the egress of personnel, hold off devices may be required for large areas or those with internal obstructions.
