Water Curtain Nozzle

GW Water Curtain nozzles are typically installed as part of a deluge system to provide a water spray barrier for protection of 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/area.

The GW Water Curtain nozzle is developed to provide a flat fan spray when water is distributed in a 240° X 15° “circular” fan from the machined orifice slot located perpendicular to the nozzle axis.

The GW Water Curtain nozzle is designed for horizontal installation. It is typically installed as part of a deluge system to protect a surface or area from heat radiation. With the orifice slot pointing upwards or downwards, the nozzle is installed between the protected surface and the heat source. The water spray will both reflect and absorb the heat radiation thus reducing the resultant level of heat reaching the protected surface.

GW AS-5414 Bush Fire - Roof Periphery Nozzle

Climate change is expected to cause more extreme weather conditions globally including more frequent and wide spread wild fires (bush fires) that can be hazardous to property in the areas affected. Australian Standard: "AS 5414 - Bushfire Water Spray Systems" has addressed this issue, and specified protective and preventitive meassures to best possible protect life, property and land.

The GW AS-5414 nozzle is developed to meet the specified requirements regarding nozzle construction and performance (water application) for protection of property (houses / buildings) against heat radiation and air borne ember and sparks.
