VSA oxygen gas generators

How it works

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

• Uses an oil-free blower, thus avoiding any oil carry-over common with oil-lubricated compressors – great for medical applications.

• Lower operating pressure minimizes the potential for water condensation.

• Not as susceptible to humid environments as are PSA systems.

• Single-bed VSA process eliminates all process valves and required manifolds.

• Low operating pressure minimizes sieve dusting (the sieve removes the nitrogen from the air), because the pressure swing is an order of magnitude lower, resulting also in lower operating cost.

• VSA Adsorber vessel has a much longer service life than PSA vessels – which commonly need repacking of sieve material every 3-5 years – again producing a much lower operating.

• 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 and EUPh 93% standard and can be as high as 95%.

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

All of the above advantages reduce the cost of preventive maintenance and repairs, thereby reducing the operating cost.

The VSA process is an extremely clean operation and the only ‘raw material’ is air.

 

On-site O2 generators allow an uninterrupted supply of Oxygen gas with a high purity output. This means that you can produce gas where and when you need it, and in the exact quantity and quality you need.

Meaning

VSA means Vacuum Swing Adsorption

• Pressure – elevated pressures, normally 4-7 Bar are needed for the process

• Adsorption – The VSA principle is used for separation of atmospheric air, where product gases are separated from others by adsorption process
