FIRE SUPPRESSION WITH WATERMIST

Watermist is defined as water droplets less than 1mm in diameter.

How does it work?
Water from the mains or a tank, flows through distribution pipework and is “atomized” to many very fine droplets, as it passes through a water mist nozzle.  Many tiny water droplets create a greater total surface area per liter of water.

The smaller droplets absorb the heat from the fire, and lowers the temperature quickly. The fine droplets in and around the fire «boils» over from water to steam, or water vapor, which is an inert gas. This conversion to water vapor, dramatically increases the volume of water, up by almost 1700 times. The water vapor displaces the oxygen near the fire, and suffocates it.

The droplets that are not converted to water vapor, will wet the surrounding area and prevent the fire from spreading.

Effectively, the fire is attacked from all sides of the Fire Triangle – Heat, Fuel and Oxygen.

BENEFITS OF LOW PRESSURE WATER MIST

Exploiting water more efficiently has its’ obvious benefits;

  • The systems demand less water, smaller water intake or tank
  • Smaller dimensions on pipes and fittings
  • Easier and faster installation and replacement
  • Discrete and space-saving design in corrosion-free materials
  • Low maintenance costs due to high quality corrosion free components
  • Effective fire suppression solution that attacks all three sides of the fire-triangle simultaneously
  • Non-toxic fire extinguishing with reduced water consumption
  • Minimal interruption of the daily operation in case of fire
