WATER SPRAY SYSTEM

A water spray system is operationally identical to a deluge system. Still, the piping system and discharge nozzle spray patterns are usually designed to protect three-dimensional components or equipment (where the deluge system is designed to cover the horizontal floor area of a room). The selected nozzles used for a specific spray pattern to conform to the three-dimensional nature of the hazard (typical spray patterns are oval, fan, full circle, narrow jet).
Examples of equipment protected by water spray systems are electrical transformers containing oil for cooling or turbo-generator bearings. Water spray systems can also be installed externally on the surfaces of tanks containing flammable liquids or gases. The water spray is intended to cool the tank to prevent tank rupture/explosion and fire spread.
