Water mist fire suppression system

Water Mist is a versatile and highly efficient fire-fighting medium. What differentiates Water Mist from traditional water based systems is its reduced droplet size. When a droplet of water vaporises, it expands by some 1,600 times. Because heat absorption is a function of surface area and not volume, smaller droplets mean more surface area and therefore faster heat absorption.

Water Mist has the unique ability to deliver water as a fine atomised mist. This mist is quickly converted to steam that smothers the fire and prevents further oxygen from reaching it. At the same time, the evaporation creates a significant cooling effect of combustion gases and blocks the transfer of radiant heat. In this way, Water Mist combines the fire suppression properties of both conventional water-based deluge or sprinkler systems and gaseous fire suppression systems.

In this way, Water Mist combines the fire suppression properties of both conventional water-based deluge or sprinkler systems and gaseous fire suppression systems.

Cooling

The water mist absorbs heat from the fire and evaporates, lowering the temperature of the fire and the surrounding area.

Smothering

The water mist displaces oxygen from the fire zone, reducing the oxygen concentration and preventing combustion.

Pre-wetting

The water mist moistens the fuel sources and surfaces, making them less flammable and preventing re-ignition.
