In a typical fire, there is intensive inter-reaction between atoms and fragments of unstable free radicals in the presence of oxygen. This continues until the burning fuel is depleted. FirePro extinguishes fire predominantly by inhibiting on a molecular level the chemical chain reactions present in combustion.
On activation of the FirePro unit, the FPC compound within is transformed into a rapidly expanding fire extinguishing condensed aerosol consisting mainly of Potassium salt-based K2CO3, H2O (vapor), N2 and CO2.
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.
