Water Mist Systems
Typically used where water damage from a standard sprinkler system may be a concern, or where water supplies are limited, water mist systems enable droplet size to be controlled and by creating a mist, an equal volume of water will create a larger total surface area exposed to the fire. The larger total surface area better facilitates the transfer of heat, thus allowing more water droplets to turn to steam more quickly. Steam, which absorbs more heat than water per unit time, will then more effectively cool the room, thus reducing the temperature of the flame.
Water mist systems can operate with the same functionality as deluge, wet pipe, dry pipe, or pre-action systems. The difference is that a water mist system uses a compressed gas as an atomizing medium, which is pumped through the stainless steel distribution pipework and onto the risk via a fine misting nozzle.
