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.
