Water Spray System / Deluge System

Water Spray System is a special fixed pipe system connected to a relible source of pressurised water supply and equipped with water spray nozzles for application on area / equipment to be protected. The system can be operated automatically by connection to an automatic detection and alarm system or manually, or both.

Water spray systems are generally used for fire protection of flammable liquid and gas storage tanks, piping, pumping, equipment, electrical equipment such as transformers, oil switches, rotating electrical machinery etc. and for protection of openings in fire walls and floors.

The piping system is connected to the water supply through an automatically actuated Deluge Valve, which initiates flow of water. Automatic actuation is achieved by operation of automatic detecting equipment installed along with water spray nozzles. There are two types of systems namely High Velocity and Medium Velocity systems.

Types of Water Spray System

Medium Velocity Water Spray Systems (MVWSS) are used for fire protection of areas with fire risks from low FP flammable liquids (FP below 65 Degree C) and also for fire extinguishment of water miscible liquids (polar solvents, alcohols etc.) small installation as it becomes cost effective and also serves the purpose of safety and location identification is easy.
High Velocity Water Spray Systems (HVWSS) are used for extinction of fires in flammable medium and heavy oils or similar flammable liquids having a flashpoint above 65 Degree C. (E.g. Transformer Fires, Lube Oil Tanks, Etc).
