Nitrogen generation based on pressure swing adsorption - NITROSWING

Mahler AGS nitrogen generation plants are based on pressure swing adsorption technology for capacities from about 200 to 4000 Nm³/h depending on the purity. Purities up to 99,99 vol.-% can be reached.

NITROSWING PSA units are designed for nitrogen generation from ambient air.

The pressure swing adsorption (PSA) technology employs the basic principle of air separation at ambient temperatures by using carbon molecular sieve (CMS; a material that adsorbs oxygen to leave a rich stream of nitrogen).

Individual plant concepts with respect to local situation (building available, etc.),
admissible sound emission can be offered. Furthermore concepts with additional oxygen removal  (DEOXO) can be considered in order to achieve oxygen contents < 3 vppm.

Additional/Optional features for nitrogen generation plants:

Our plants are used worldwide. Especially for Russia, Belarus and Kazakhstan we are able to provide our plants with all necessary TR certificates and declarations for the import and operation in the Custom Union. Our NITROSWING plants are equipped with a serial declaration according TR CU 010/2011 (MD), TR CU 004/2011 (LVD) and TR CU 020/2011 (EMC), valid until beginning of 2020. Certificates or declarations according TR CU 032/2013 for all pressure vessels as well as a TR CU 012/2011 certificate for the entire equipment placed inside areas with potentially explosive atmospheres are also part of our scope of supply.
