What's New In Plant & Equipment

New product eliminates the risk of fireNew product eliminates the risk of fire

The UK’s leading fire suppression and safety specialist Nobel Fire Systems in conjunction with Isolcell, now offers the market leading oxygen reduction fire prevention system, N2 FireFighter.

The atmosphere we breathe consists mainly of a mixture of nitrogen (78%) and oxygen (21%).   Nitrogen is an inert gas; Oxygen is the natural substance aiding every combustion process, including human respiration.

A fire will only exist if sufficient oxygen continuously reaches it to support the speed of the reaction. When the amount of oxygen is not sufficient, a fire will suddenly be extinguished.

The methodology of the N2 FireFighter is based on that principle: to keep the atmosphere in the areas to be protected low in oxygen, less than normal ambient. This will automatically extinguish and inhibit combustion while remaining safe for humans.

The effect of this auto-extinguishing atmosphere on humans is the same as the air at 3,300 m elevation; the partial pressure of oxygen at that height is equal to the partial pressure of oxygen in the methodology of N2 FireFighter.

Traditional fire-fighting systems have been conceived to automatically extinguish fires. N2 FireFighter prevents the start of any combustion in the protected areas by monitoring and controlling the proportion of oxygen to nitrogen in the enclosed atmosphere.
