Every RICH oxygen system is tested at the factory.
For PSA oxygen generators, the cost for oxygen production, or cylinder filling is normally stated in kilowatt hours (KWH). The reason being that the air is free, but there is a cost of electricity to operate the air compressor. At a sea level site elevation, it will cost about 10 KWH to fill a 6m3 size oxygen cylinder, or 1.5 KWH per M3.
Liquid oxygen (LOX) at 99% oxygen purity may have some advantages for metal cutting, but not necessarily for medical applications.
The delivery pressure of oxygen from a PSA oxygen generator can usually be increased to the high end of the scale by decreasing the flow from the plant. Higher pressures would require an oxygen booster or compressor.
RICH specifies Atlas Copco air compressors because of their overall value, dependability and the fact that they have the best international service network in the business.
PSA oxygen generators/PSA nitrogen generator provide the best performance when the feed air has a dew point of 40 degrees F (4 degrees C) or less. Depending on the model selected and or the feed air equipment (air compressor, dryer, air tank and feed air filters) supplied, humidity control may or may not be required for the room. Consult factory for recommendations on a specific applications.
PSA Oxygen Generators/PSA Nitrogen Generator provide the best performance in temperatures between 40 degrees F (4 degrees C) and 80 degrees F (27 degrees C).
PSA incorporates a material called molecular sieve for gas separation. This zeolite based sieve has a preferential adsorption for nitrogen. Clean dry air is passed through the sieve beds on the oxygen generator, producing an oxygen enriched gas.
PSA is one of several technologies currently in use for separating oxygen or nitrogen from air.
