Watermist systems suppress fire using very fine water droplets rather than the larger drops produced by a conventional sprinkler. Because the mist has a huge surface area, it cools the fire and the surrounding air rapidly and turns to steam, which displaces oxygen around the flames. The result is fast, effective suppression using a fraction of the water a sprinkler needs, which means far less water damage. MEP designs, supplies and installs watermist systems for a wide range of buildings and industrial risks across the UK.
Watermist attacks fire in three ways at once: it cools the flames and hot gases, it displaces oxygen as the droplets flash to steam, and it blocks radiant heat, slowing fire spread. The fine droplets are produced by specially designed nozzles fed at either high or low pressure. Using much less water than a sprinkler, watermist controls a fire quickly while keeping water damage to a minimum, which makes it attractive where the contents of a building are valuable or sensitive.
Watermist suits a broad range of applications, from machinery spaces, engine rooms and industrial processes to heritage buildings, hotels, residential blocks and data centres where water damage must be limited. It is also widely used in the marine sector. Systems can be engineered for local application to a specific hazard or for total flooding of a room. We design each system to the appropriate standard, such as BS 8489, and to the relevant approvals for the risk being protected.

A fire suppression system that uses very fine water droplets to cool a fire and displace oxygen, controlling it quickly while using far less water than a sprinkler.
Sprinklers use larger water droplets and much more water. Watermist uses a fine spray that cools and smothers the fire with a fraction of the water, so it causes less damage.
No. Using much less water than a conventional sprinkler is one of its main advantages, which is why it suits heritage, residential and equipment-heavy spaces.
In machinery and engine rooms, industrial processes, heritage buildings, hotels, residential blocks, data centres and marine vessels, among others.
Yes. Unlike some gaseous agents it does not reduce oxygen to hazardous levels across the room, so it can be used in occupied spaces when correctly designed.
