VSA Oxygen Generator

To produce oxygen from air, Gas Generators International uses a proprietary Vacuum Swing Adsorption (VSA) process that eliminates many of the design problems associated with traditional Pressure Swing Adsorption (PSA) systems.

Designed for easy installation and for safe, reliable, unattended operation, Gas Generators International offers on-site, on-demand industrial gas generators to supply high purity oxygen for a variety of applications including: power plant cooling, metal processing, float glass manufacturing, wholesale gas, small chemical, and semiconductor production.

Multiple generators can be used to meet specific gas requirements and redundancy needs. Gas Generator International’s engineering team routinely designs and provides necessary support equipment, piping, and conduit systems for complete oxygen plants.

We also have a range of Cabinet Housed PSA Oxygen Generators and High Pressure Oxygen Gas Booster Systems that are available for rental. These are continuously on and off rental so please contact us for more details.

PCI’s unique Vacuum Swing Adsorption (VSA) technology has several advantages over the more commonly used PSA process:

  1. Use of an oil-free blower, thus avoiding any oil carry-over that is common with oil-lubricated compressors and is great for medical applications.
  2. Lower operating pressure minimizes the potential for water condensation.
  3. The VSA System is not as susceptible to humid environments as PSA systems are.
  4. Single-bed VSA process eliminates all process valves and required manifolds.
  5. Low operating pressure minimizes sieve (the sieve removes nitrogen from the air) dusting, because the pressure swing is at an order of magnitude lower, which also results in lower operating costs.

The VSA Adsorber Vessel:

Has a much longer service life whereas PSA vessels commonly require repacking of sieve material every 3-5 years. This, again, presents a much lower operating cost.

Shows no, or significantly less, degradation of performance at high altitudes, unlike PSA technology.

Needs no feed air compressor (> 50% saving vs. conventional systems).

Meets the USP 93% standard and can reach as high as 95%.

Is a turn-key integrated solution, so there is no need to size / source air compressors, dryer systems, and product or feed buffer tanks.
