Corrosion Resistant Sprinklers, Finishes & Materials

Corrosion Resistant Sprinklers, Finishes & Materials

While our standard sprinklers are manufactured from brass, we offer several special finshes and materials for maximum corrosion resistance and operating life in even the toughest industrial or marine environments. A common application is salt-laden air in coastal or offshore locations. These include Electroless Nickel Plating (ENP), high grade stainless steels (SS316 and SMO254), nickel aluminium bronze and titanium.

Typical applications for stainless steel sprinklers (where corrosive atmosphere exist) • Chemical and Petrochemical Processing • Pharmaceutical Processing • Food and Beverage Processing • Power Generation—nuclear • Marine • Pulp and Paper • Medical • Textiles • Petroleum Refining • Water Treatment • Salt-water areas • Parking garages • Chemical storage areas • Mechanical rooms • Industrial manufacturing sites

Sidewall Horizontal Extended Coverage (WWHEC)

Sidewall Horizontal Extended Coverage (WWHEC)
The WWHEC is designed for installation along a wall or the side of a beam and beneath a smooth and level ceiling. Commonly used instead of pendent or upright sprinkler heads due to aesthetics or building construction considerations, where piping across the ceiling is undesirable.

Sealed Window Drencher

Sealed Window Drencher
The Sealed Window Drencher sprays dense water drops to form a flat fan spray water curtain. It cools windows during a fire and so prevents them from breaking. This in turn restricts the supply of oxygen to the fire and hinders its spread, especially if the space between buildings is small.

Electrically Actuated Sprinklers (by Metron Actuator ®)

Electrically Actuated Sprinklers (by Metron Actuator ®)

Electrically actuated sprinklers provide the option of designing "intelligent" pro-active sprinkler systems. Each individual sprinkler head can be operated individually through the programming of the fire detection system. Thus a single, or a number of sprinklers in the area of detection can be actuated instantly when the early fire is detected, thus allowing for fast containment and suppression of the fire. Electrical actuation of sprinklers thus significantly speeds up the release of water onto the fire, compared to the time otherwise required for the fire to develop to a size where the sprinkler is released by heat. Detection of the fire will typically be by means of heat, smoke or flame detection - or combinations of these. An electrically actuated sprinkler will operate both as a "normal" heat-actuated sprinkler AND as a remotely controlled sprinkler actuated by electrical signal, thus offering double purpose protection. These specialist sprinkler heads incorporate electrically activated Metron Actuators. An electrical signal from a detection device ignites a small quantity of explosive that forces a piston to extend into and break the glass bulb. They operate within milliseconds of receiving an impulse, a rate which is almost imossible to achieve with a mechanical source of energy.
