Clean room air handling unit Nimos

Nimos systems applying PSA technology use machinery that is installed in a designated room. Separation of the molecules requires high-pressure compressed air, as with membrane technology, and this entails increased energy consumption. However, this technology can be indicated when a compressed-air system is already present or when the position where these machines are installed is very far away from the area to be protected. Elements in the Nimos system For PSA technology, the following elements must be installed: 1. Compressor 2. Cyclone separator 3. Compressed air tank 4. Electronic condensate discharge 5. Universal filter 6. Air dryer 7. Fine filter 8. Micro filter 9. Activated carbon filter 10. PSA nitrogen generator 11. Process tank How the Nimos system works 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.
