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.
