HIGH VELOCITY WATER SPRAY SYSTEM

A high velocity water spray (HVWS) system is a type of fire protection system that uses high velocity water sprays to extinguish fires. fires involving liquids with flash points of 65-degree C (150-degree F) or higher. Three principles of extinguishment are employed in the system - emulsification, cooling and smothering. It is typically used in industrial settings, such as Transformer, Burners-Air preheating systems and Lubricating oil systems. Hydrogen cooling and seal oil systems, Inside Turbo - alternator sets, Clean and dirty oil tanks & where there is a risk of fires involving flammable liquids or gases.


The system uses a network of pipes that are installed throughout the protected area and are fitted with High Velocity spray nozzles. When a fire is detected, the system is activated and water is discharged through the nozzles in the form of a high velocity spray. The high velocity water spray is designed to extinguish the fire by cooling the flames, removing heat, and reducing the oxygen content in the air.


The water spray from the HVWS system is applied at a higher velocity than a medium velocity water spray system.


The HVWS system is typically designed to operate automatically, but can also be manually activated by a person. It is an effective means of controlling fires and preventing them from spreading to other areas. HVWS systems are subject to regular testing and maintenance to ensure their reliability in case of an emergency.
