The power behind SEM-SAFE® high-pressure water mist For a fire to survive, it relies on the presence of the three elements of the ‘fire triangle’: oxygen, heat and combustible material. The removal of any one of these elements will extinguish a fire. The SEM-SAFE® high-pressure water mist system goes further. It attacks two elements of the fire triangle: oxygen and heat. The uniqueness of high-pressure water mist is that it combines the suppression effect of gas and sprinkler systems. As well as removing the oxygen like a gas fire suppression system, it simultaneously cools the fire like a traditional sprinkler. The cooling effect additionally lowers the risk of re-ignition. A unique fire fighting system The SEM-SAFE® high-pressure water mist system is a unique fire fighting system. When water is forced through nozzles at high-pressure, a super-fine mist is formed that has a two-fold extinguishing effect. As well as cooling the fire like a traditional sprinkler, it simultaneously starves the fire of oxygen like gas fire suppression systems. When the mist comes into contact with flames, it evaporates and expands a minimum of 1,700 times. The dense vapour created displaces the flames and quickly extinguishes the fire.
