Fire Sprinkler that doesn't require a tank | Automist

Automist can be connected to the existing water main

When considering active fire suppression systems (AFSS) the provision of an adequate water main is often the responsibility of the homeowner. Ensure that your quote covers all the costs required to complete your installation.

Traditional fire sprinklers cannot be fed from the mains as they require 60 litres per minute (lpm) and 2-3 bar of pressure in order to operate. The cost of supplying water can significantly increase the cost. The majority of water companies recommend at least a 32mm diameter supply pipe, instead of a standard 25mm pipe.

While it should be possible to supply traditional sprinkler directly from the mains, in many cases a tank is needed to store the 600-1000 litres of water. Weighing as much as a tonne they often take up valuable storage space in your loft with the load spread over multiple joists.

Automist is different, it consumes less water than a power shower (6 lpm, 1 bar) and therefore can be connected seamlessly to a dwelling's existing water supply.
