WATER SPRAY NOZZLES

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.

Categories

Thermospray

Thermospray

Medium velocity solid cone spray pattern. Ideal for exposure protection and combating fuel fires with flash point below 66°C.

Sealed Thermospray

Sealed Thermospray
Medium velocity solid cone spray pattern.

Fyrhed

Fyrhed

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.

Tankcool

Tankcool
Specially designed for use on bulk fuel storage tanks. Highly effective in preventing structural damage by cooling during a fire and in fighting fires in floating roof storage tanks.

Wafer Spray

Wafer Spray
Used for exposure protection of narrow objects such as pipes, flanges or steelwork.

Drencher Nozzle - Marine

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.

Water Curtain Nozzle

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.

Open Window Drencher

Open Window Drencher

The GW Window Drencher is developed for wetting and cooling of vertical surfaces. It is installed horizontally, and the specially developed deflector provides a vertical down and 15° reverse, wide spray that generates an evenly distributed water run-down on the vertical surface behind it.

Cable Tray Nozzle

Cable Tray Nozzle
Used for the protection of cable and pipe trays against radiant heat or fire. Specially designed to give NFPA rate with minimal wastage.

Thermocool

Thermocool
Provides exposure protection for horizontal or vertical structural steelwork and other flat surfaces. Specially developed distribution pattern provides protection by direct impingement without the excessive water wastage of ordinary nozzles.

Long Throw Horizontal

Long Throw Horizontal
Specially designed for the fire protection of atria.

Atrium (LTH+ELTH)

Atrium (LTH+ELTH)
Combination of Long Throw nozzle LTH and ELTH for extended horizontal coverage up to 13 m.

Thermoshield

Thermoshield
Used as a radiant heat shield and to control gas leakages.

Flat Fan Foghed

Flat Fan Foghed
Horizontal partition nozzle that distributes a flat fan of water or foam through 360 degrees. Used for cooling or forming a water curtain.

Fog Nozzle

Fog Nozzle
Low velocity water spray nozzle that produces a spray comprising very fine water droplets. Used to extinguish fire in enclosed areas such as duct work, engine compartments and conveyors.

Foam/Water Nozzles (open, air aspirating, SS316)

Foam/Water Nozzles (open, air aspirating, SS316)

The Foam/Water nozzle is of the air-aspirating type, designed for low-expansion in the ratio of 5:1 to 7:1 (@1 to 7 bar). The nozzle is mounted in the pendent position to produce a solid cone discharge.  Produces a high quality foam blanket for fast flame knockdown and security against reignition and burn back. Typical applications: proces area protection, road and rail tanker loading bays, warehousing and air craft hangars.

Swivel Adapter

Swivel Adapter
The GW Swivel Adapter is a flexible ball joint that allows for easy directional adjustment and fixation of spray nozzles. This feature is especially useful for applications where standard fitting components do not meet the specific angle and space requirements for the design. The Swivel Adapter is available in a variaty of high durability metal alloys - to satisfy the demands of fire protection systems in the most challenging environments.
