Watermist

Introduction

Watermist is a versatile and highly efficient fire-fighting medium. What differentiates Watermist from traditional water based systems is its reduced droplet size. When a droplet of water vaporises, it expands by some 1,600 times. Because heat absorption is a function of surface area and not volume, smaller droplets mean more surface area and therefore faster heat absorption.

Watermist has the unique ability to deliver water as a fine atomised mist. This mist is quickly converted to steam that smothers the fire and prevents further oxygen from reaching it. At the same time, the evaporation creates a significant cooling effect of combustion gases and blocks the transfer of radiant heat. In this way, Watermist combines the fire suppression properties of both conventional water-based Deluge or sprinkler systems and gaseous fire suppression systems.

However, smaller droplets do not necessarily mean better performance. Droplets must have the necessary momentum to get to the seat of the fire where they rapidly cool, and expand to deny the fire oxygen.

Utilising the unique properties of Watermist, Tyco Fire & Integrated Solutions have designed and developed both a low and a high-pressure version of WaterMist delivering droplet momentum to the seat of the fire.

Branded as ProtectoMist® Low Pressure Water Mist and MicroDrop® High Pressure Water Mist, both these systems have unique features and benefits that are designed to combat a wide variety of specific fire risks within the industrial/commercial, marine, Oil & Gas and Power Generation/Transmission market sectors.
