Misting technology outperforms sprinklers

20 March 2020

Testing undertaken by fire suppression specialist Plumis shows that sprinklers can take up to a minute longer than Automist to activate in response to certain fires.

In the latest detailed analysis of fires attended by fire and rescue services, published by the Home Office, figures show that cooking appliances were by far the largest ignition category for accidental dwelling fires and non-fatal casualties from accidental dwelling fires. Accounting for 48 per cent of these fires and 51 per cent of non-fatal casualties 2018-19.

To understand how better to tackle these types of incidents, Plumis conducted tests at the Burn Hall at the Fire Protection Association (FPA) to see how different fire suppression technologies measure up. From the testing, Plumis has published a video showing how sprinklers perform in comparison to Automist Smartscan against a challenging oil fire.

The results found that the traditional sidewall sprinkler activated after one minute and 49 seconds in comparison to the Automist Smartscan, which took just 55 seconds. Once activated, the Automist Smartscan was able to successfully put the fire out in one minute and eleven seconds. However, it took the sprinkler one minute and 45 seconds, which is just over half a minute longer than the misting suppression system.

High-pressure water mist, as used in the Automist Smartscan, is highly effective in protecting people and their homes against fires caused by deep fat fryers and is regarded as a more efficient and environmentally friendly alternative to sprinklers – using ten times less water to achieve the same result.

The testing follows a series of contract wins for Plumis with Lambeth Council to pilot its misting system in an array of housing schemes.
