Essentially, this is how a nitrogen generator works: it separates nitrogen molecules from the oxygen molecules within compressed air, resulting in a purified supply of nitrogen. Generating nitrogen can be done with a membrane nitrogen generator or a PSA (pressure swing adsorption) nitrogen generator connected to a compressor. But which technology to use? Well, it depends on the nitrogen quality you require. If, for example, you just need to inflate tires or use nitrogen to prevent/suppress fires, then a low nitrogen purity level of 90-99% and a membrane nitrogen generator will suffice. However, a PSA nitrogen generator is required when you have to achieve very high purities of 99.999% or 10 PPM (parts per million) and even higher – for example in the food industry or for plastic molding.
In addition to allowing companies to control how much nitrogen they want to produce with how much pressure and which degree of purity, generating the gas themselves has other benefits. They are no longer subject to price fluctuations on the market, save transport costs, and prevent delays. In addition, businesses generating their own nitrogen do not have to face the safety hazard that come with handling high-pressure cylinders, they incur no waste related to boil-off losses or have to return high pressure bottles that can never be fully emptied. Over time, the initial investment for a nitrogen generator pays off because operating costs are kept significantly lower compared to getting nitrogen from a third party.
