Zeolite Molecular Sieve Oxygen Plant Hospital Oxygen Equipment

Using PSA technology, the ETR medical PSA oxygen generator can produce 93%±3% purity oxygen gas directly from compressed air. Compared with traditional bulk liquid oxygen and cylinder oxygen, ETR on-site PSA oxygen generators can reduce costs by up to 50%.

Compressed air is purified through an air dryer and filters to a certain level for the main generator to work with. An air buffer is incorporated to ensure smooth supply of compressed air and reduce fluctuations in the air source. The generator produces oxygen using PSA (pressure swing adsorption) technology, a proven method for oxygen generation. Oxygen of desired purity at 93%±3% is delivered to an oxygen buffer tank for smooth delivery of the product gas. Oxygen in the buffer tank is maintained at 4 bar pressure.
