NK＇s marine extinguishing system is safe and environmentally friendly.

Inert Gas

The IG541 is developed as an alternative to halon or carbonic acid gas in order to protect safety of people and environment. It makes up with 52% nitrogen, 40% argon and 8% carbonic acid gas. 15% oxygen is, at least, needed to maintain combustion. The Inert Gas system eliminates what might reduce the oxygen ratio which is expected to add non-activated gas by 12.5%. Also, the system is designed to protect people who might be threatened by the effect of reduced oxygen in a blazing location.
