AIR GASES

MAHLER designs and delivers high-performance oxygen generation systems based on VPSA technology - tailored to industrial requirements, scalable, energy-efficient, and built for continuous operation.
How MAHLER VPSA Oxygen plants work
Advanced VPSA Technology for Maximum Oxygen Efficiency
Using vacuum pressure swing adsorption (VPSA) with high-performance zeolites, MAHLER plants separate ambient air into a rich oxygen stream with purities up to 94 vol.-%. Our flexible designs allow investment- or energy-optimized configurations, adapted to your local requirements and production processes.
Plant Data
| Feedstock | ambient air |
| Hydrogen capacity | 약 300 to 5.000 Nm³/h |
| Purity | up to 94 vol.-% |
| Pressure | about 1,2 bar(abs) |
Why Oxygen VPSA?
- Low-cost, on-site oxygen production
- Fully automatic operation (no operating personnel required)
- Flexible product flow and purity levels
- Fast start-up and automatic part-load adjustment, Remote monitoring and support
- Compact, skid-mounted units for quick installation
- High system availability and long service life


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.
Plant Data
| Feedstock | ambient air |
| Hydrogen capacity | 200 to 4.000 Nm³/h |
| Purity | up to 99,99 vol.-% |
| Pressure | about 6 – 9 bar(abs) |
