A water mist fire suppression system uses a network of pipes and nozzles to discharge very fine water droplets, creating a mist that effectively cools and smothers fires. This method enhances heat absorption, displaces oxygen, and can prevent fire spread by reducing radiant heat. Water mist systems are known for their efficiency, using significantly less water than traditional sprinkler systems and minimizing water damage.

How water mist systems work

These systems work by discharging pressurized water through specialized nozzles that atomize the water into a fine mist. The mist rapidly cools the fire and surrounding area, displaces oxygen, and reduces radiant heat.

Icon
Cooling

The tiny water droplets absorb heat and evaporate rapidly, significantly cooling the fire and surrounding gases

Icon
Oxygen displacement

The rapid vaporization of water into steam expands and displaces oxygen at the fire's source, suffocating the flames

Icon
Radiant heat attenuation

The fine mist creates a barrier that helps block radiant heat, protecting people and property from its effects
