How it works?

FirePro removes the flame free radicals and extinguishes fire without depleting oxygen.

Conventional fire extinguishing agents extinguish fire by:

• Suffocation or asphyxiation: depletion of oxygen levels in air below 15% at normal pressures extinguishes fire
• Cooling: heat absorption

FirePro condensed aerosol on the other hand, extinguishes fire predominantly by inhibiting the chain chemical reactions present in combustion on a molecular level.
It removes the flame free radicals and extinguishes fire without depleting oxygen.
In a typical fire, atoms and fragments of unstable free radicals react between them in the presence of oxygen. This continues until the burning fuel is depleted or the fire is extinguished by other means.
On activation of the FirePro Condensed Aerosol Generator Unit its solid compound is transformed into a rapidly expanding condensed aerosol consisting mainly of Potassium salt-based K₂CO₃, H₂O (vapor), N₂ and CO₂.
The gas type 3-D properties of the condensed aerosol particles facilitate their even and fast distribution as well as their flow into the natural convection currents of combustion.
The solid particles of Potassium salts, a few microns in size are suspended in an inert gas, and display an extremely high surface to reaction mass ratio that increases efficiency thus reducing the quantity of material required.
When the condensed aerosol reaches and reacts with the flame, Potassium radicals (K*) are formed mainly from the disassociation of K₂CO₃.
The K*s bind to other flame free radicals (hydroxyls- OH-) forming stable products such as KOH. This action extinguishes fire without depleting or absorbing the ambient oxygen content. KOH reacts further in the presence of CO₂ and forms K₂CO₃.
