ETR PSA Oxygen Generator
With PSA principles, ETR medical PSA oxygen generator can produce 93%±3% purity oxygen gas directly from compressed air. Compared with
traditional Bulk liquid oxygen and cylinders oxygen, ETR on-site PSA oxygen
generator can reduce cost down to 50 percentages. They can produce oxygen by
your will, overcoming the limits of distance, location and transportation.
Compressed air is purified through the air dryer and
filters to a certain level for main generator to work with. Air buffer is
incorporated for smooth supply of compressed air thus to reduce fluctuation of
compressed air source. The generator produces oxygen with PSA (pressure swing
adsorption) technology, which is a time proven oxygen generation method. Oxygen
of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply
of product gas. Oxygen in buffer tank is maintained at 4bar pressure.
