How does a nitrogen compressor work?

To put it another way, a nitrogen generator operates by separating nitrogen from oxygen in compressed air. Generating the gas in-house offers additional advantages besides letting businesses decide how much nitrogen they want to create, how much pressure they want to use, and what purity they want. In the beginning, the nitrogen unit was supplied with liquid nitrogen at –196 C. Once a high-pressure nitrogen compressor compresses the liquid, a heat source converts it into a gaseous state.
