High-pressure water mist has become indispensable in the rail vehicle industry.
The technology is used in particular in passenger compartments, diesel power packs, diesel and electric locomotives, and for protecting special vehicles. FOGTEC Rail Systems high-pressure water mist systems offer particular advantages when it comes to protecting passenger areas. Due to their compact dimensions, small pipe diameters, and comparatively low weight, retrofitting a high-pressure water mist system in rail vehicles is usually straightforward and cost-effective.
The system is characterized by low life cycle costs and high operational reliability.

Aerosol systems are not only cost effective, but also suitable for use in extreme environmental conditions. The aerosol is electrically non-conductive and therefore does not interfere with electronic components during firefighting. Activation triggers a chemical reaction in the aerosol container, producing an aerosol containing nitrogen, water, and potassium.
The aerosol extinguishes the fire not by a smothering effect (oxygen depletion) or by cooling, but by inhibiting the chemical combustion reaction at the molecular level. In addition, the chain reaction that occurs during a fire is interrupted by the binding of free radicals. The oxygen in the ambient air is not removed.
The aerosol contains microparticles. These particles are suspended in an inert gas, in which the ratio between the exposed surface area and the reaction mass is extremely high. (This means that the amount of active material required for firefighting can be reduced to a minimum). The small particles remain suspended in the air for a long time, allowing them to penetrate the natural convection of the existing fire. This increases the efficiency of the extinguishing agent.
Gas extinguishing systems are ideal for use in enclosed technical areas.
The systems are compact and can be easily integrated into equipment cabinets, switch cabinets, or higher-level systems. Gas extinguishing systems usually operate on a nitrogen basis. They do not produce any harmful fire by-products, as is the case with chemical extinguishing gases. They also generally have no effect on technical equipment. As a non-toxic element, nitrogen extinguishing systems can be used freely throughout Europe.
