THE ADVANTAGE OF VSA OXYGEN TECHNOLOGY OVER PSA OXYGEN TECHNOLOGY
PCI’s unique Vacuum Swing Adsorption (or VSA oxygen) technology has several advantages over the more commonly used PSA oxygen process:
- 01
USE OF AN OIL-FREE BLOWER, thus avoiding any oil carry-over that is common with oil-lubricated compressors and is best practice for medical applications.
- 02
LOWER OPERATING PRESSURE minimizes the potential for water condensation.
- 03
SYSTEM IS NOT as susceptible to humid environments as PSA oxygen systems are.
- 04
SINGLE-BED VSA OXYGEN process eliminates all process valves and required manifolds.
- 05
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 50% lower operating costs.
SIMPLIFIED VSA TECHNOLOGY
COMPLEX PSA TECHNOLOGY
PCI’s elegant VSA Technology saves operating costs and minimizes maintenance, when compared to other complex PSA systems.
The VSA Adsorber Vessel:
Has a much longer service life whereas PSA oxygen 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 oxygen 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, which also results in 50% lower operating costs.
