Fire sprinkler systems are specifically designed to either suppress or extinguish a fire”

Conventional Sprinkler Systems are designed primarily to control the fire and prevent building structural collapse, and pre-wet the surrounding combustibles to prevent fire spread.  This is achieved using copious quantities of water.

Water sprinkler systems are specifically designed to either suppress or extinguish a fire.  Water is an outstanding fire suppression agent due to its high heat capacity and latent heat of vaporization. Critical to water mist efficacy is the nozzle which is specially designed to produce a specific range of droplet sizes and velocities.

The larger droplets have sufficient energy and momentum to penetrate the fire plume and cool the fuel.  The smaller droplets increase the overall enthalpy of the enclosure as well as being converted to steam at the flame front and entrained into the plume thereby displacing oxygen. Extinguishment is achieved by a combination of this mechanism including equipment Alarm check valve closed bulb sprinkler open sprinkler and deluges valves, other associated parts flow switch, temper switch zone control assembly engineer test connections and computerized hydraulically calculated piping network as per NFPA standards. A deluge fire sprinkler system is similar to a pre-action system except the sprinkler heads are open and the pipe is not pressurized with air. Deluge systems are connected to a water supply through a deluge valve that is opened by the operation of a smoke or heat detection system. The detection system is installed in the same area as the sprinklers. When the detection system is activated water discharges through all of the sprinkler heads in the system. Deluge systems are used in places that are considered high hazard areas such as power plants, aircraft hangars and chemical storage or processing facilities. Deluge systems are needed where high velocity suppression is necessary to prevent fire spread.Deluge valve is used in deluge systems and used for fast application of water in a spray system. Deluge valves are used under conditions that require the rapid application of large volumes of water and, for that reason, are often integral components in fire protection systems
