As well as combustible material, any fire must have heat and oxygen to grow.
As fine water droplets spread towards a fire, they quickly absorb heat energy, evaporating to form steam. Steam has a dramatic cooling effect. As atomised water mist droplets expand 1600-1700 times, they absorb far more energy than water from a sprinkler.
At the same time, the steam displaces oxygen and combustible gases, starving the fire of another essential driver. The combined effect is to smother the fire, cutting off its oxygen supply and cooling the combustible material and associated gases.
This buys vital life-saving time for people to escape. Fine water mist does not impede their evacuation. Having controlled the fire, temperature and smoke, the water mist also prevents the fire from re-igniting.
Damage to property is limited further because of the comparatively low volume of water involved and the absence of the heavy run-off caused by a sprinkler system.
Years of hands-on experience in domestic fire protection and building construction have gone into the design of Halo.
The components of our system are robust and reliable, and manufactured to ISO 9001 quality standards:
Each ceiling-mounted nozzle contains a temperature-sensitive bulb, which shatters – only, and without fail – when the ambient temperature reaches 57°C, activating the Halo system.
The Halo nozzle nearest the fire instantly emits a fine spray of water droplets over the area (up to 16m2 per nozzle).
Compact and discreet, the Halo nozzle slots into a standard downlight fitting (GU10).
Also manufactured to ISO 9001, in the UK, the Halo high-pressure pump runs off mains water at 12 ltrs/min and 140 bar.
A compact unit, the pump set can be located in a cupboard, basement or other discreet location. Electrical power is provided by a standard 20Amp / 230V supply, separately fused, with a power failure alarm.
A complete auto mist system. Once activated, the pump triggers an audible alarm independently of any smoke or fire alarms in the property. As an option, an alert can also be relayed to a remote monitoring service or the property owner/manager.
Lightweight and flexible high-pressure hoses connect the nozzles and pump(s). A priority demand valve ensures that mains water is dedicated to the Halo pump when it is activated.
