Why Choose Absstem?
Industries We Serve
Absstem installs on-site PSA plants tailored to purity, pressure, and flow requirements.
How On-Site PSA Gas Generation Works
Air Intake
Filtered, dried, and compressed atmospheric air enters the PSA system via the integrated compressor and dryer unit.
PSA Separation
Advanced molecular sieves (zeolite for oxygen, carbon molecular sieve for nitrogen) selectively separate the target gas from compressed air using pressure swing adsorption cycles. One adsorber vessel produces gas while the other regenerates.
On-Demand Gas Delivery
High-purity gas is delivered directly to your hospital pipeline or industrial process – continuously, safely, and automatically. IIoT sensors monitor purity and flow in real time.
Typical On-Site Plant Performance
- Oxygen purity: 93–96%
- Nitrogen purity: 95% to 99.999%
- Energy-efficient operating cycles
- IIoT-enabled remote monitoring
Trusted by Leading Hospitals & Industries
