Puck and Automist: a comparison

We are often asked how Automist Smartscan compares to a more conventional watermist sprinkler system such as Puck.

The answer is that they are totally different animals, and in 2018, Automist has a number of advantages:

  • Accidental activation and leaks in your walls and ceilings are almost impossible with Automist, and in a fire, water damage is reduced
  • Automist's performance has been independently certified: you are not dependent on the manufacturer to interpret the ins and outs of a test report.
  • Automist has fewer design limitations, for example it works in large rooms that a single Puck pump cannot serve
  • Costs are similar.

There's really no comparison. Take a look at the table below to see how Automist comes out on top.

*A single Puck system is limited to two sprinkler heads per room by BS 8458:2015 section 6.6.1. In practice this means that a Puck system is not compliant if any room is wider than 5.1m or has an area of more than 32m2 . For example, a standard Puck system cannot serve a room of 5.1m x 5.4m and comply with BS 8458. A room of 5m x 9m can be served by a single Smartscan nozzle and a pump shared with other rooms, while Puck's BS 8458 solution would require two separate pumps and four nozzles.
