SEM-SAFE High-Pressure Water Mist System for Accommodation

Danfoss Semco · Denmark

High-pressure water mist fire suppression system for accommodation areas on marine vessels including public spaces, corridors, cabins, storage areas, and outdoor balconies. Uses closed-type nozzles with heat-sensitive glass bulbs (typically 57 degrees C) that activate automatically. The same pump unit can serve accommodation, engine room, and bilge sections. In standby, maintains nozzle pressure of 10-15 bar; on activation, pump delivers water at 100 bar through micro-nozzles creating fine mist that cools and displaces oxygen simultaneously.
