When a small quantity of water is sprayed at high pressures to make very fine disjointed droplets of water with an exponentially larger surface area, it is called water mist. When this water mist reaches the fire source it rapidly evaporates due to high temperature and increases its water volume by 1640 times. This leads to the generation of an inverting effect by locally displacing oxygen at the fire source.
When the water vapour starts to displace oxygen from the fire, it leads to starvation of Oxygen. Once this oxygen is completely depleted, the fire starts losing intensity and is extinguished. Water mist is the ultimate form of fire extinguishing for water sensitive areas and situations such as Class C electronic fires and Class A fires.
This is a great system for hospital environments, traditional and electronic data storage areas, and telecommunication facilities amongst other places.
