Water mist system

Nobel Fire Systems has completed the installation of two high pressure water mist systems for Barclaycard.

The benefits of water mist are created through the use of the available water supplies with nozzles designed to produce much smaller droplets of water, approximately 1/100th the size of those in sprinkler systems. This increases the surface area interface with the fire and so absorbs much higher levels of heat energy. In general, HP water mist systems will use only 10% of the water used by sprinklers, with the added advantage of also being able to cover larger floor areas. There is an increase in the minimum pressure requirements which tends to be around 100 bar. The resulting lower water demand reduces the size of water storage, enabling more storage of required water supply with a much smaller floorspace footprint and results in decreased distribution pipe diameters.
