Most effective and reliable ways to control a fire

Typically installed across a building’s ceiling, a sprinkler system is one of the most effective and reliable ways to control a fire, thereby safeguarding people and property. From simple wet-pipe systems to pre-action, dry and deluge systems, we can specify and supply the exact system for your needs.

  • Wet pipe

    Connected to the main water system, wet-pipe systems contain water under pressure ready to operate as soon as a fire is detected. Simple, reliable and affordable, they are by far the most common in use. How reliable? They’ve achieved their function of controlling fires 99.5% of the time, in all recorded cases since their first installation in NZ in 1880. And, according to the Insurance Council of New Zealand, faulty activation is in the range of one in 16 million sprinklers–significantly lower than the overall risk of fire.

  • Dry pipe

    In a dry-pipe sprinkler system the pipes are filled with pressurised air or nitrogen, not water. This gas holds a remote valve, in a heated space, closed so that water won’t enter the pipe until a fire causes one or more sprinklers to operate. Typically, dry-pipe systems are used where there is a risk of water freezing in the pipes.

  • Pre-action

    Like a dry-pipe system, water is not normally contained within the pipes. The difference is that water is withheld from the piping by an electrically-operated valve: the pre-action valve. Controlled by independent flame, heat or smoke detection, this means a dual action is required for water release, giving an added level of protection against inadvertent discharge. Pre-action systems are especially suitable for water-sensitive environments like computer servers, rare-book libraries, archives and fine-art galleries.

  • Deluge

    Chemical processing and storage, aircraft hangars, power plants–these are just some of the applications for the deluge systems we supply. Similar to a pre-action system but not gas-pressurised, a deluge valve is opened by detectors placed with the sprinklers, discharging throughout the whole system, delivering widespread fire suppression.
