Water Curtain Nozzle

Water Curtain Nozzle

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.

Water Curtain Fire Protection Nozzle

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.
