Inergen Gas Extinguishing System
Operating principle
The INERGEN gas combines the latest generation of chemical extinguishing agents with 25/42 bar pressure extinguishing system. The nitrogen is used to transport the gas to the individual nozzles, where it evaporates rapidly, creating a homogenous atmosphere in the room.
Advantages
- No risk of personal injury
- Faster than extinguishing systems using natural gases, extinguishing agent release in less than 10 seconds.
- High environmental compatibility (GWP = 1/ALT (half life) of 3 to 5 days), no effect on the ozone layer (ODP=0).
- Extinguishing agent storage takes up little space as consumption is very low.
- Low extinguishing agent concentration needed.
- Pressure – free transport of the extinguishing gas.
- Possible to use existing piping systems, e.g. when upgrading Halon 1301 systems.
- Modular design option using multiple extinguishing agent storage containers in the protected area.
Properties of Inert Gases
- Inert gases are colourless, odourless and electrically non-conductive.
- The extinguishing efficiency of the inert gases is due primarily to its ability to reduce the oxygen level present in the surrounding air to such a proportion that the fire can no-longer burn.
