Nitrogen liquid the increased purity, the first grade

Nitrogen is the most demanded gas for providing vzryvo-and fire safety in various areas of the industry: from food to nuclear. Being inert gas, nitrogen allows at its giving in technological volume to force out oxygen and to avoid oxidation reaction. Burning represents reaction of fast oxidation which is caused by existence in the atmosphere of oxygen, and also an ignition source — a spark, an electric arch, chemical reaction with considerable allocation of heat. For prevention of ignition it is necessary not to allow such reaction. In the environment with concentration of nitrogen about 90, process of burning becomes impossible.
