Water Mist fire systems
Gielle’s high performance precision components
Small droplets deliver big fire protection
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.
Utilising the unique properties of Water Mist, Gielle offer both a low and a high-pressure version of Water Mist applications to provide your facility with the right solution in the event of a fire.
Water Mist systems – low pressure solution
Water mist systems maintain the simplicity and reliability of traditional sprinkler and Water Spray Deluge Systems - the difference being the reduction in droplet size. The effect of this is increased heat absorption and decreased water damage. Water Mist systems offer two nozzle options; Sealed Nozzles for sprinkler equivalent systems and Open Nozzles for total flood systems.
Water Mist systems – high pressure solution
The Water Mist systems – high pressure solution is a total flood system designed to protect Class B flammable liquid hazards in machinery spaces, both insulated and non-insulated combustion turbine enclosures, generator enclosures, and flammable liquid storage
