Mist Fire Protection Sprinkler Systems
Water Mist Fire Protection Sprinkler Systems by Fire Defence are mainly used to protect domestic and residential premises.
Water mist sprinkler systems range from low pressure (4 - 16 bars)* systems providing a fine water spray extinguishing medium to high pressure (40 - 120 bars)* systems producing a very fine water particle mist.
The water is propelled either by pumps or by an inert gas and dispersed from nozzles that are designed to deliver water in a range of fine droplet sizes to the area of fire. The suppression mechanism relies on fast absorption of heat by the small water droplet size and the production of steam that displaces oxygen from the area of the fire to a level that cannot sustain combustion.
High pressure water mist systems resemble gaseous extinguishing systems while low pressure systems are more akin to sprinklers or water spray/deluge systems.
