What is it

What is water mist and how does it work?

Water mist is a water spray containing very small water droplets. A watermist system distributes water mist through specially designed nozzles to control, suppress, or extinguish fires.

Watermist

Water mist is a water spray for which 90% of the total volume of liquid is in droplets of a diameter smaller than 1000 microns.

How does it work

Water in the form of mist is more effective in suppressing fire compared to just water. The water mist droplets are smaller and finer, which gives them a larger surface area and thus a larger heat absorption surface. This enables the mist to suppress a larger area of the fire without using more water.
Water mist fights fire in different ways including cooling the flames and surrounding gasses through evaporation, displacing oxygen by evaporation, diminishing radiant heat, and by wetting the fire.

The benefits of watermist

Water mist systems offer many benefits. One of the key benefits is water usage. Compared to traditional sprinkler systems, water mist systems use approximately 85% less water. The reduced water consumption makes the systems more sustainable. In addition, water mist systems only use potable water as a suppression agent and are therefore harmless to people. By using less water, the water mist systems ensure minimal water damage to buildings and the interior and minimize interruptions and downtime as well as the financial cost of a fire.

Watermist systems are cost-effective. The systems are easier and cheaper to install and maintain than traditional sprinkler systems. This is due to watermist systems can be designed with smaller components and smaller diameter pipes. The water storage tanks for watermist systems are smaller than those required for traditional sprinklers, and therefore, require less storage space. In case of facility expansion, the watermist systems can be easily retrofitted and extended.

Environmentally friendly

The water mist systems only use potable water as a suppression agent and are safe for people and the environment.

Tests and approvals

Water mist systems require listed approvals which are obtained through application-specific fire testing. Each application needs to be full-scale fire tested to obtain these approvals. The application-specific fire testing includes a specific set of fire tests that need to be passed.
The fire testing must be performed in an ISO 17025 accredited test laboratory and should be witnessed by a notified body or an AHJ.
