DESCRIPTION
The GW-S sprinkler series offers high quality, European manufactured, modern compact design, that meet the rigid test
requirements set out by the world leading approval authorities. The unique GW PTFE / double groove seal in
combination with high end heat responsive frangible glass bulbs guarantee durable operation and reliable performance.
All manufacturing and testing processes are performed strictly in compliance with our quality management system,
certified to ISO 9001.The use of precisely CNC-machined hot forged frames eliminates the risk of porosity.
The heat & electrically operated sprinkler is fitted with an electrically operated Metron Actuator that enables instant and
remote actuation of the sprinkler – typically in combination with a detection system and/or a manually operated switch
box.
APPLICATION
GW-S heat & electrically actuated sprinklers are used in fixed fire protection systems. Care must be exercised that RTI,
orifice size, temperature rating, deflector style and sprinkler type is in accordance with the latest published sprinkler
installation standards i.e. EN12845, CEA4001 or NFPA13.
The GW-S heat & electrically actuated sprinklers are ideal for applications where instant and fully controllable actuation
of single or multiple heads is called for – e.g. applications involving protection of explosive components/environments.
OPERATION (Metron Actuator)
The Metron Actuator is a highly reliable, compact single shot device which can push with a power to weight ratio in
excess of 10,000:1. It operates within milliseconds of receiving the appropriate electrical impulse, a rate which is almost
impossible to achieve with a mechanical source of energy. The short reaction times and high power to weight ratios are
achieved by sophisticated pyrotechnique. Within the metal body of each device, rapid expansion of hot combustion
products generates very high pressures which are used to do mechanical work, in this case to drive a piston forward to
shatter the sprinkler glass bulb.
Its ability to rapidly convert small electric signals into high mechanical work output, its compact size, high reliability and
good environmental resistance makes the Metron Actuator ideal for automatic or remote controlled fire protection
applications.
