Water is chemically neutral. Atomized, it can dissipate a lot of heat particularly quickly and thus cool substances below their minimum combustion temperature. The smaller the droplets, the larger the specific surface area of the water and the better the evaporation and cooling effect. This prevents damage and ignition of flammable materials due to the effect of heat. In addition, the volume of water increases by a factor of 1640 during evaporation and displaces the oxygen in the vicinity of the fire.
Both extinguishing components, nitrogen and water, are ecologically and health-friendly – a good 79% of atmospheric air consists of nitrogen. They do not affect the ozone layer or global warming and do not form any harmful reaction products during extinguishing. After a fire has been extinguished, the flooded room can be easily ventilated via ventilation systems or windows.
