Inergen is a composition of natural of gases found in the atmosphere and thus there are no environmental issues relating to its potential discharge. The extinguishing principle behind fixed extinguishing systems with INERGEN® is oxygen replacement. This means that the oxygen content in the atmosphere which is about 20.9% is lowered to somewhere between 10-14%. At this oxygen level most common fires will die out. Where other extinguishing agents just lower the oxygen level, INERGEN® distinguishes itself by maintaining an oxygen level which ensures that people can remain in the room.

Reduces oxygen levels in the room to below flame threshold but sufficient oxygen for breathing.
