Water Spray System

Overview:

High velocity water spray system has been designed to extinguish oil fires. It introduces an entirely new principle in fire extinguishing. It is employed to bring about a fundamental change in the nature of the flammable liquid, which is converted temporarily into an emulsion that cannot burn.

All oils are water repellent, and so do not melt. Therefore, the cooling action of water applied in the form of a jet or low-pressure spray is negligible. The basic principle used in high velocity spray system is the use of water in the form of fine mist.

Commercial Buildings, Factories and Power Plants

System Description:

This High velocity water spray system consists of high velocity water spray nozzles, sprinkler bulbs, deluge valves and piping. This system employs either wet pilot or dry pilot actuation. There will be two pipelines running adjacent to each other around the equipment to be protected. One is the detection line provided with normal sprinkler bulbs and the other is a dry pipeline fitted with high velocity spray nozzles. Wet pilot system uses water in the detection pipeline whereas compressed air is used in the dry pilot system. The detection pipeline connected to the deluge valves keep the diaphragm of the valve in closed position.During detection of fire and breakage of sprinkler bulbs, the pressure in the detection line reduces, resulting in the opening of the deluge valves and the release of water in the mist form to the protected area.

The rapid movement of the broken streams of water is suddenly arrested at the oil surface and the impact causes the oil to be broken up into tiny globules to form an emulsion with water. In addition, the dispersion of oil into the minute globules in the water gives instantaneous cooling, thus preventing formation of oil vapor.

We manufacture and supply medium velocity water spray system that is used for:

• Fire risks involving lighter oils/ LPG

• Protection of vessels, plant and structures exposed to heat from adjacent and surrounding fires.

Overview:

Fires involving liquids with flash points below 32°C cannot always be extinguished by high velocity water spray system, and in such cases medium velocity water sprayers giving medium water drop sizes are employed. Water is sprayed directly over the protected surface, preventing dangerous temperature rise and distortion. Medium velocity water spray system also provides effective control by cooling and extinguishing, thus preventing fire from spreading to adjacent areas and from causing loss or damage to other areas.
