How HI-FOG^® fights fire

HI-FOG^® controls, suppresses or extinguishes fires by discharging a fine water mist at high velocity.

The water mist is made by discharging plain, potable water at high pressure through specially designed, patented HI-FOG^® sprinkler or spray heads. The water mist is discharged at high velocity by the system’s high-pressure pumps or accumulators.

Attacking the fire

The micro-droplets of HI-FOG^® represent water in its most effective fire fighting form. The high pressure enables the water mist to penetrate into the fire.

The small droplets vaporize very fast and, when doing so, absorb heat very efficiently. At the same time, the water mist expands 1,760 times, displacing the oxygen at the seat of the fire.

Protecting the surroundings

HI-FOG^® water mist also provides an efficient water curtain, which blocks the radiant heat, preventing the fire from spreading or reigniting. Smoke particles also bind with the droplets, preventing the smoke from spreading.

Using little water

HI-FOG^® delivers extremely good performance, combating fire by removing two of the main elements a fire needs to survive: heat and oxygen. This is achieved with remarkably little water: HI-FOG^® uses up to 90% less water than conventional sprinkler solutions.

The fire fighting effectiveness of a water mist system is defined by drop size distribution, the number of droplets, and penetration to the fire. The combination of these properties is entirely system-specific.
