NESS Water Mist Fire Extinguishing and
Cooling Systems (NEWM)
Extinguishing and cooling in one system
Thermal oil leaking into a hot heater can be dangerous, even when there is no flame. Light ends, evaporating at temperatures of 250°C or below, can accumulate inside the heater. Together with the oxygen in the air, they can form an explosive mixture which may ignite at hot surfaces.
The NESS extinguishing and cooling system sprays a very fine water mist into the hot water heater. This flushes the heater volume, reduces the oxygen concentration and at the same time cools the heater by the evaporation of the water droplets. The spray head for the water mist is fully automatically driven in case of fire with a lance in the burner, but can also be triggered manually. An automatic self-test program checks the smooth functioning regularly.
