WATER SPRAY NOZZLES
The GW premium quality range of water spray nozzles is designed for use in professionally engineered deluge fire protection systems. Ideal for providing exposure protection in special and high hazard applications, such as: capital equipment in refineries, offshore platforms, power stations, process plants, tank farms and LPG/LNG installations.
Medium velocity solid cone spray pattern. Ideal for exposure protection and combating fuel fires with flash point below 66°C.
High velocity solid cone spray pattern. Ideal for exposure protection and combating fuel fires with flash point above 66°C. Suitable for use where long throws are required or outdoors in high wind speeds.
The GW type “S” range of Drencher Nozzles offers the latest in design and performance, both highly compact and durable. Drencher Nozzles are open sprinklers, available in two different styles and with different orifice sizes (K-factors) to accommodate most system design requirements.
The GW Water Curtain nozzle is developed to provide a flat fan spray where water is distributed in a 240° X 15° “part-circular”, perpendicular to the nozzle axis. The GW Fyrhed Water Curtain 360 nozzle is developed to provide a dense full circle flat water spray (curtain) to protect persons or structures from open fire heat radiation. Examples are escape routes, flare / burner areas on oil rigs, etc.
They are typically installed as part of a deluge system to protect structures or persons from heat radiation - e.g. escape routes. The water spray will both reflect and absorb the heat radiation thus reducing the resultant level of heat reaching the protected surface.
The GW Window Drencher is developed for wetting and cooling of vertical surfaces. It is fitted with a specially developed deflector which provides a vertical down and 15° reverse, wide spray that generates an evenly distributed water run-down on the vertical surface behind it. Open Window Drencher type nozzle provides effective exposure protection on storage tanks and as a fire barrier for doors, walls and windows.
