Wat e r m is t s y s t e m
As one of the world’s few manufacturer, Danfoss Semco can offer protection of
your engine room with a true high-pressure water mist without any additives.
The advantage of the Sem-Safe system is that the very small quantities of water it
uses are harmless to personnel and equipment.
Even electrical equipment is left undamaged, provided that protection is better
than IP 22.
hi g h a n d l ow p r ess u r e
co 2 s y s t e m s
The Sem-Safe system is approved by all major classification societies IP 23.
­Consequently, it can replace Halon or can be used as a substitute for traditional
CO2 ­systems.

How water mist func ti ons
Water mist is water that, at a high-pressure of 100 bar, creates a fine mist or fog. The fine water mist evaporates
very quickly and the resulting steam starves the fire of oxygen, suppressing it. At the same time, the water evaporation creates the most efficient form of cooling. In this way, the fire is extinguished both by oxygen suppression
and cooling, providing the advantages of both water and gas-based fire fighting.
High-pressure systems only create a high pressure during extinguishing. High pressure water mist will cool the
areas around hot metal surfaces and the water mist evaporates before it reaches the hot metal. In this way, shock
cooling and changes in metal structures can be avoided.
Danfoss Semco has been working with high-pressure water mist right from the start. This revolutionary
new ­ system is finding its way into more and more application areas, offering an efficient system that is
­environmentally friendly as well as harmless to users.
Approval levels and experience. We have already seen fires being almost instantly extinguished
by the system after its release, thus saving repair costs and off-hire periods.
