|What is Watermist
Why is Watermist so good?
What makes watermist so effective for so many different applications?
Uses less water than conventional sprinkler systems
• Using typically only 10% of the water that a traditional sprinkler system uses has
many benefits including:-
• Less damage to property/equipment, fast/cheap cleanup and
• Alleviates run-off concerns, in areas such as “cut off” rooms containing
• Helps minimise run-off volume, water usage is critical in Europe where building owners must provide a collection area for run-off.

Works in partially ventilated area
Unlike Halon,CO2 or Hypoxic systems, water mist will work in areas where doors or
vents have been left open. Gas or air conditioning based systems
typically require a sealed area so that the gas concentration can be achieved to
extinguish the fire (or in the case of Hypoxic prevent fire starting.
Smoke Scrubbing Qualities
Some smoke and toxic gases are absorbed by the atomized spray and eventually
settle with the water.
Safer than CO2
There have been numerous instances of injuries and even deaths as a result of
accidental CO2 discharges during routine maintenance and other situations.
Watermist is not only environmentally benign but totally safe for occupied areas.
WaterMist & WaterFog
are environmentally sound
| Prevents Re-ignition
Because of its fast and effective Because effective
cooling effect and volume filling
ability, watermist systems are very
good at preventing re-ignition
even of oil bath or other
“pool” type fires. In Factory
Mutual Research tests attempts
to re-ignite fires with a torch were
often impossible because the
watermist put the torch out.
