Water Mist System is a fire protection system which uses very fine water sprays (i.e. water mist) The small water droplets allow the water mist to control, suppress or extinguish fires by cooling both the flame and surrounding gases by evaporation. displacing oxygen by evaporation water droplet size in this systems is less than 1000 microns. (Water Mist Systems is future of Fire Protection). Water Mist Systems is applicable for class A,B & C fires. In this the fire is suffocated & the water fog itself provides extremely effective cooling of fire in surrounding areas.
