How do water mist fire suppression systems work?Tauren Corsinie
The iMist suppression system and traditional fire sprinkler systems work in the same way when it comes to activation when there is a fire. Both systems wet the surface of the fuel, and the surrounding area, to cool and suppress the fire like a blanket of water. However, only
the water mist fire suppression systems work in all
three ways simultaneously, with minimal water to extinguish a fire;
- Upon activation of a water mist nozzle, the system will begin to discharge high pressure water mist. The mist will fill the 16m2 area (per nozzle) with a fine mist – which will travel around the room, dampen all surfaces it can get to and thus, restrict fire spreading.
- When the water is discharged at a high pressure, the room temperature is reduced dramatically due to a reaction between the fast-moving colder air molecules and water molecules against the heat from the fire, much like cold air displacing hot air.
- As the water mist has direct contact with the flame, it turns into steam. The steam particles then displace the oxygen particles around the fire and thus, suffocates the fire.
Unlike many Hollywood films, only the nozzles situated in the area of the fire will release the mist.
