High Pressure Water Mist System

The Hyper mist or high pressure water mist fire fighting system is installed for all-important ship’s machinery systems in the engine room (ME. AE, Purifier, Boiler etc.). The high-pressure water mist/fog system provides water mist protection during emergencies to engine room areas and machinery spaces. This system is independent of any other fixed fire fighting system such as foam or CO2 system. A fresh water pump takes suction from fresh water tank to supply high-pressure water to the sprinkler system. Each area is isolated by valves, which can be opened during emergency situations involving fire. The system is kept at constant stage of readiness. High-pressure water is injected through a special nozzle working within pressure range of 4 to 10 MPa (depending upon the design of the system), which breaks the water droplets into fine mist. The diameter of the water mist particle range from 50 to 200 µm which improves the fire extinguishing effect and efficiency of the system. The distance between any two nozzles is very critical as area covered by one nozzle must be such that no space is left unsprayed in the fire affected area. Operating the high pressure water mist system during installation in the World's Largest Ship - Maersk Triple-E. Watch the video to learn how water mist is used to suppress fire in ship's machinery such as - Main Engine, Purifier, Boiler, Auxiliary engine etc. For more interesting videos, visit www.marineinsight.com/
