High Velocity Water Spray System:
- High velocity water spray systems are installed to extinguish fires involving liquids with flash points 65C (150F) or higher.
- High velocity water spray system is to protect Transformers.
- The system comprises of network of underground and above ground piping, control valve (Deluge Valve), sprinkler bulb detectors, water spray nozzles/Projectors.
- System is pressurized with water up to below the control valve (deluge valve) using pumps and connected to a reliable source of water supply. The piping network above the control valve remains empty consisting open spray nozzles/projectors.
Medium Velocity Water Spray System:
Designed in accordance to international standards, this system is 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.
Some of the areas where this system is widely used are
- Working plants like LPG bottling plants, chemical plants where flammable solvents are stored and/ or used etc.
- Horizontal storage vessels (like LPG Bullets, NH3 storage tanks etc.)
- Vertical storage vessels (like benzene, xylene, toluene tankage etc.)
- Spherical storage vessels (like LPG bullets, spheres etc.)
- Spot protection (Protection of selective areas/ equipments)
