Test Result
WM system activates
Effective cooling reduces the temperature of the fire in a very short time. Temperature away from the source drops below re-ignition temperature. Safer environment during fire activation.

Advantages of Water Mist
Less water required / usage.Typically uses 10% of the volume of water required by a sprinkler system.
Less damage.Water mist is not a deluge system, it smothers fire by means of droplet expansion.
Less down time after a fire in a production environment.
Typically equipment with a IP24 rating or greater will not even be affected by water mist.
Easier installationPipe work diameters are substantially smaller than required by a sprinkler system.

Suitable Applications for Water Mist
Libraries Hotels Hospitals
Typical applications and benefits for Water Mist. Suppressing the fire to prevent spread. Absorbing smoke to keep clean air available to breathe. Allows more time for evacuation.

Suitable Applications for Water Mist – Cont.
Transformer SubstationUnderground Tunnel
Typical applications – Cont. Less down time after activation. Absorbing smoke to decrease damage. Less water consumed. Keep temperatures low and maintain high visibility. Easier to recover and resume activity.
• Frangible bulb protection from false activation.
• Continual development of the Domestic System
