High Velocity/Medium Velocity Water Spray System
High Velocity Water Spray System
High Velocity water spray systems are installed to extinguish fires involving liquids with flash points of 65o C (150o F) or higher. Three principles of extinguishment are employed in the system - emulsification, cooling and smothering. The result of applying these principles is to extinguish the fire within a few seconds.
Most Common application of High Velocity Water Spray System:
- Transformers, oil filled equipments of power stations
- Turbo-alternators and other
- Oil fired boiler rooms, oil quenching tanks.
Medium Velocity Water Spray System
Medium Velocity Water Spray Systems are installed to control the burning and to provide cooling and/or exposure protection to such risks where extinguishment is always not possible or even desirable e.g. fires involving flammable fluids having flash points below 65o C (150o) . These 60o C systems are also used sometimes for power station applications in coal conveyors, cable galleries etc.
