Vehicle Fire Suppression System


FirePro’s VELEX Vehicle Fire Suppression system offers fire detection and automatic or manual fire suppression for the protection of various types of vehicles. It works by detecting fire in the engine bay and promptly suppressing it using a unique, eco-friendly dual-extinguishing action (hybrid) system.

Non-pressurized Technology

The VELEX fire protection system employs two fire extinguishing agents. The primary agent, a liquid, is stored at atmospheric pressure in one of the two chambers of the system’s cylinder, with the other remaining empty. A FirePro condensed aerosol generator containing the FPC aerosol forming solid compound, stored also at atmospheric pressure, is connected to the cylinder. Upon detection of fire, the solid compound in the container, transforms into a highly effective fire extinguishing condensed aerosol, which fills the empty chamber of the cylinder. Pressure in the chamber rises only for a few seconds to enable the rodless piston present between the two chambers to discharge the liquid extinguishing agent. This is being dispersed inside the protected enclosure through a network of piping and nozzles into the protected area. When the liquid extinguishing agent is fully discharged, the FirePro condensed aerosol is itself released through the nozzles further augmenting the extinguishing process.


R-107 Certified

There are hundreds of buses every year that encounter a fire related incident. Two-thirds of these incidents start in the engine bay and pose a serious danger to passengers. FirePro VELEX is approved and is in accordance with the United Nations Economic Commission for Europe (UNECE) Regulation No. 107 (R107), after successfully passing tests defined by the specific protocol. The process includes rigorous testing through various fire risk scenarios.


Approved by the Federal Motor Vehicle Transport Authority

VELEX holds a type-approval by the Federal Motor Vehicle Transport Authority (KBA) in Germany (107R07/02*0070*00) for use as a fire suppression system for vehicles used for the carriage of more than 8 passengers. KBA contributes towards road safety in Europe and environmental protection across Germany and beyond.

Environmentally Friendly

The liquid extinguishing agent used in VELEX is environmentally friendly and biodegradable. In addition, it is chemically stable, glycol free and has the right concentration of advanced corrosion inhibitors. The condensed aerosol is produced through the sublimation process of a patented solid forming compound developed with eco-friendly materials. It has zero Global Warming Potential (GWP) and zero Ozone Depletion Potential (ODP).
