High-efficient Nitrogen PSA
Plants / Generators
NITROSWING PSA plants generate nitrogen on-site directly from ambient air. The pressure swing adsorption (PSA) process uses carbon molecular sieve (CMS) to separate oxygen from the air at ambient temperature, leaving a nitrogen-rich gas stream.
HOW MAHLER NITROGEN PSA PLANTS WORK
PSA Technology for Efficient Nitrogen Generation
In the pressure swing adsorption process, ambient air flows over CMS adsorbers. The CMS preferentially adsorbs oxygen, allowing nitrogen to pass through as the product gas. By cyclically switching between adsorption and desorption phases, a continuous nitrogen stream is produced – fully automatic, with short start-up time and no operator required.

Frequently asked questions
Questions about our nitrogen plants
What nitrogen purity can be achieved with NITROSWING plants?
With N2-PSA systems a purity up to 99,99 % (nitrogen + argon) can be reached, which corresponds to a remaining oxygen concentration of 100 vppm. An additional oxygen removal unit (DEOXO) can be supplied to achieve oxygen contents below 3 vppm.
What are the advantages of NITROSWING compared to liquid nitrogen supply?
Using the NITROSWING for on-site nitrogen generation reduces logistics costs, ensures a continuous supply, and allows the production of nitrogen directly tailored to process demands.
How do NITROSWING plants ensure a continuous and reliable supply of nitrogen?
The PSA cycle alternates between two adsorption vessels, which are supported by a buffer vessel and flow control. This ensures stable product flow, pressure, and quality.
Can custom configurations be provided?
Yes. Mahler AGS offers tailored solutions that account for site-specific conditions, such as building layout and noise limits.
