Inergen fire suppression system

Inergen gas is the fire suppression system of choice for areas that contain high value or critical areas.

Inergen is a mixture of three naturally occurring gases; 52% nitrogen, 40% argon and 8% carbon dioxide, and has no ozone depletion potential and does not contribute to global warming. It quickly suppresses the fire without further damaging sensitive equipment and does not require a time consuming clean up of the extinguishant agent afterwards. It is also one of the safest fire extinguishing gases proven to have no ill effects on people or the environment.

Inergen is stored as a compressed gas, therefore there is no fogging or misting when it is released, so exits remain clearly visible. When an Inergen system is discharged, it smothers the fire by reducing the concentration of oxygen in the room from the normal levels of 21% to around 12.5%. most substances will not support combustion below 15%, therefore the fire condition will be quickly extinguished.

Inergen suppression systems do not impact on protected equipment because it is clean, dry and electrically non-conductive. It also does not produce toxic or corrosive residue.

Inergen gas systems are installed in line with smoke detection systems, which are able to detect potential fires at the early stages. As soon as the detection system confirms a potential fire incident, the inergen suppressant will be released into the protected area.

This type of agent is an effective extinguishant that can be used on many types of fires. It is designed for total flooding protection against Class A surface burning, Class B flammable liquid, and Class C fires occurring within an enclosure by oxygen depletion.

Cylinders can be located upto 200 metres away from the protected area, and by the use of directional valves a single bank of cylinders can provide protection across a number of areas.
