FirePro Technology

Transformation Process

In a typical fire, there is an intensive reaction between atoms and unstable free radicals in the presence of oxygen. This process continues until the burning fuel is depleted. FirePro suppresses fire predominantly by inhibiting, on a molecular level, the chemical chain reactions of combustion.

On activation of the FirePro condensed aerosol generator, the FPC compound is transformed into a rapidly expanding fire suppression condensed aerosol consisting mainly of Potassium Carbonate K2 CO3 (active agent), N2 (inert gas), H2O (vapor), and other carrier gasses in minor quantities. The gas-type, 3-D properties of the condensed aerosol, facilitate its even and fast distribution in the protected volume, as well as its flow into the natural convection currents of combustion.


The solid particles of Potassium salts which are a few microns in size, suspended in a ratio a blend of gases forming a medium that behaves like a gas with total flooding properties. This increases efficiency - which results in less quantities of fire suppression agent required.When the condensed aerosol reaches and reacts with the flame, Potassium radicals (K*) are formed mainly from the disassociation of K2 CO3. The K*s bind to other flame free radicals (hydroxyls - OH-) forming stable products such as KOH. This action suppresses fire without significantly depleting the ambient oxygen content. KOH reacts further in the presence of CO2 and forms stable K2 CO3.

The solid particles of Potassium Carbonate (K2 CO3) have a diameter of less than five microns and remain in suspension in the protected area. Hold times determined by the standards are often exceeded, preventing further re-ignition of the fire.
