Nitrogen Plants

Best engineering performance made in Germany

High-efficient Nitrogen Generator by PSA | Mahler AGS

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).

Plant features of the NITROSWING nitrogen generation plant:

Low cost on-site production
Fast start-up , fully automatic and unattended operation
Product flexibility regarding flow and purity
Completely pre-manufactured skids
High availability and reliability
Design for long lifetime


Typical Applications for Nitrogen Generator Plants:

Metallurgical / heat treatment
Chemical and petrochemical industry
Float glass
Food industry
Electronic industry
Oil and gas

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 2025. 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

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.
