FirePro Technology

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

When the FirePro condensed aerosol generator is activated, the FPC compound transforms into a rapidly expanding condensed aerosol for fire suppression, consisting mainly of potassium carbonate K2CO3 (active agent), N2 (inert gas), H2O (vapor) and other carrier gases in small quantities. The gaseous, 3D properties of the condensed aerosol facilitate its even and rapid distribution throughout the protected volume, as well as its penetration into the natural convection currents of combustion.

The solid potassium salt particles, several microns in size, suspended in a proportional mixture of gases, form an environment that behaves like a gas with full flooding properties. This increases efficiency - resulting in less fire suppression agent required.

When the condensed aerosol reaches and reacts with the flame, potassium radicals (K*) are formed mainly from the dissociation of K2CO3. K* binds with other free radicals (hydroxyls - OH-), forming stable products such as KOH. This action suppresses the fire without significantly reducing the oxygen content in the environment. KOH further reacts in the presence of CO2 and forms stable K2CO3.

The solid potassium carbonate (K2CO3) particles have a diameter of less than five microns and remain suspended in the protected area. The hold times specified by standards are often exceeded, which prevents fire re-ignition.
