What is HI-FOG® water mist?

HI-FOG is the trade name of the high-pressure water mist fire protection system developed, manufactured and delivered by Marioff.

The HI-FOG water mist fire protection system can be used in place of deluge, gas, foam, dry chemical and traditional sprinklers, as well as any other type of fixed fire protection system.

HI-FOG water mist

HI-FOG controls, suppresses and extinguishes fires by discharging a fine water mist at high velocity. The water mist is made by the system when it activates, by pushing plain, potable water through specially designed and patented HI-FOG sprinkler and spray heads at high pressure. The water mist is discharged at high velocity using high-pressure pumps or accumulators.

HI-FOG water usage

HI-FOG uses three mechanisms to fight fire: cooling, radiant heat blocking and local oxygen inerting. Traditional sprinkler systems use wetting as their main mechanism, and therefore use very large amounts of water. Conversely, HI-FOG utilizes water much more efficiently: it uses up to 90% less water than traditional sprinkler systems while producing better or equivalent results.
