A deluge system dispenses large quantities of a fire suppressing fluid – typically either water or foam – very quickly when a fire is detected or the system is manually activated. This starves the fire of oxygen and/or fuel, helping to extinguish the flames proactively.
Deluge systems are used in high hazard areas such as power plants, aircraft hangars, and chemical plants. These systems are very effective in hazardous areas because they release water or another fire suppressant to all the open sprinkler heads simultaneously
