A guide to watermist:
a fire sprinkler alternative
Watermist fire protection systems share many similarities with traditional fire sprinklers, both deploy water onto an affected area via ceiling or wall-mounted nozzles.
The main difference is the working pressure. Sprinklers typically operate below 12 bar [175 psi], while high-pressure watermist operates above 35 bar [500 psi].
Watermist systems work by rapid cooling the fire via vaporisation into steam, rather than drenching the fuel and surrounding surfaces.
Watermist systems consume up to 90% less water than sprinkler systems, this efficient use of water brings several advantages:
smaller or no water tanks required
opportunity to connect directly to the mains water supply
smaller diameter distribution pipework
