FirePro Condensed Aerosol Fire Suppression Systems

FirePro Systems manufactures, markets and distributes worldwide the environment friendly FirePro Condensed Aerosol Fire Extinguishing Systems – the leading brand in the condensed aerosol fire extinguishing technology.

The company’s Headquarters are in Limassol, Cyprus where also located, are our manufacturing facilities that use the latest technology to produce the patented FPC aerosol forming compound and assemble the FirePro Condensed Aerosol Fire Extinguishing Units according to the relevant international standards and requirements and rigorous quality controls

Over the last 20 years our company has built a global distribution network extending to more than 75 countries in all continents. To date FirePro installations have been completed in more than 110 countries for a well-diversified portfolio of clients.

How It Works

Conventional fire extinguishing agents use the following methods to extinguish fire:

  • Suffocation method (depletion of oxygen levels in air below 15% at normal pressures extinguishes fire)
  •  Cooling method (heat absorption)
  •  Removal of fuel

FirePro aerosol on the other hand, extinguishes fire 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 Aerosol Generator its solid compound is transformed into an aerosol consisting mainly of Potassium salts (e.g. K2CO3) H2O, N2 and CO2.



The gas type 3D properties of the 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, suspended in an inert gas, display an extremely high surface to reaction mass ratio – increasing efficiency and reducing the quantity of material required.



When the aerosol reaches and reacts with the flame, Potassium radicals (K*) are formed mainly from the disassociation of Potassium salts e.g. K2CO3. The K* bind to other flame free radicals (hydroxyls) forming stable products such as KOH. This action extinguishes fire without having to deplete oxygen.

Protection Method

FirePro Condensed Aerosol Fire Extinguishing Systems are used in as a total flooding agent protection of enclosures. However, unlike traditional gaseous agents, the total flooding effect is achieved without increasing the pressure in the enclosure. Upon activation, the fire extinguishing condensed aerosol is evenly distributed using the energy produced in the transformation process of the FPC compound from the solid  to the aerosol phase.

FirePro Condensed Aerosol Fire Extinguishing Systems can protect, volumetrically, enclosures of any size; from volumes of less than a cubic metre to volumes of thousands of cubic metres.


FirePro Systems – ISO 9001:2008 and 14001:2004 Certified, is based in Cyprus, and specializes in the manufacture and supply of patented Fire Extinguishing Condensed Aerosol Systems, according to the latest generation of stable FPC aerosol forming solid compounds with no pyrotechnic materials, and environmentally friendly.

Upon activation, the solid compound is transformed into a rapidly expanding, highly efficient and highly effective fire extinguishing condensed aerosol based on potassium salts.

The condensed aerosol extinguishes fire by breaking the uncontrolled chain chemical reactions of combustion without depleting oxygen. In the process, flame-free radicals are removed.

All FirePro products are suitable for Fire Classes A, B, C & F (according to EN2 Classification) and A, B & C (according to NFPA10 Classification).
