Nimos nitrogen generators using PSA technology, based on the principle of molecular separation, use specific activated charcoal filters to separate nitrogen from the oxygen present in the air. A flow of compressed air, previously dried and filtered, supplies the columns containing the sieves that filter the air inside the PSA generator.
The separation phase happens under pressure (from 6 to 10 bar). While one column is regenerated to eliminate the oxygen captured, another performs the separation by capturing the oxygen molecules and allowing the nitrogen molecules to pass through. The cycle repeats continuously, ensuring a continuous, steady supply.
The Nimos generators are completely automated, and are equipped with an oxygen analyser and a microprocessor that controls their operation.
