Watermist Ecological. Does not harm environment Safe for protection of equipment & occupied areas Minimal water damage Efficient for flammable liquid fires Electrically non conductive (demineralised water) Rapid temperature reduction Independent system or pumping equipment Economical. Minimum cost of extinguishing agent

The watermist system optimises the quantity of water used, maximising effective water volume by means of distribution of droplets of very tiny size, which produce a cooling effect. Thus, damage is reduced by reduction of volume of water used. The system operates at working pressures of 80 to 200 bar, producing droplets of very small diameter at very high velocity. Spray heads are designed to discharge water in the form of water mist. Water mist systems provide a fast and efficient suppression for class A, B and C fires, eliminating the hazard of re-ignition (offering an incomparable capacity of suppression of deep-seated fires). One of the most outstanding factors is the small amount of water used.

We offer several models of spray WATER MIST heads, depending on the hazard to be protected. Spray heads are made of stainless steel, incorporating a filter to prevent obstructions. Micronozzles, which produce proper water mist, are made of stainless steel suitable for a working pressure of 200 bar. Currently water mist systems can be found on merchant and naval ships protecting machinery rooms, generator rooms, berths and public areas.

The option to use water mist systems as an alternative has increased to cover such areas as data processing centres, archives, subways, escalators and transport.

Water mist owes its extinguishing efficacy to the joint actuation of 3 main effects:

• Smothering: Vapour generated displaces an equivalent of oxygen volume, thus producing a smothering effect.

• Cooling: Water spray in droplets of micrometric size produce a large heat collector surface.

• Attenuation: Mist generated in the enclosure absorbs a great amount of radiant heat, thus protecting adjacent objects.

A dilution effect is also observed: Actuation of water mist contributes to decrease of flammable vapour concentration up to levels below flammability limits.
