X-MIST® SYSTEM extinguishes or controls fires by cooling, oxygen displacement by water vapor and radiant heat attenuation. The exceptional cooling effect of water mist is a result of the division of water into very fine droplets, which increase the total surface area available to absorb heat and maximizes the evaporation rate of the water. This system is fire extinguishing system to protect machinery space of category A and cargo pump room.


- In case of total flooding water mist system application onboard, the protected volume was limited by the same fire testing volume space and it restricted the application of total flooding water mist system onboard.

- For many years, the continued R&D efforts on water mist system to extend the protected volume has been carried out and finally, the new regulation (IMO MSC.1/Circ.1385) comes into effect since December 2010.

- Scientific methods on scaling of water mist fire testing volume are applied to the protected volume onboard.
