1.  Description For Air  Separation Plant Gas Generation Equipment Oxigen 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
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.

2. Advantage For Air  Separation Plant Gas Generation Equipment Oxigen Generator
  • Highly efficient molecular sieves, making oxygen generation more efficient
  • Unique startup concentration maintenance function
  • Imported muffler, achieving an operating noise of less than 85dB(A)
  • LCD touch screen interface, making setting of operating parameters more convenient
  • Integrated pipeline process, providing excellent air tightness
  • Intelligent control, enabling remote data transmission.

3.  WORKING PRINCIPLES For Air  Separation Plant Gas Generation Equipment Oxigen Generator
The medical molecular sieve PSA oxygen generator system adopts the international advanced pressure swing adsorption (PSA) technology to form a rapid cycle of pressurization adsorption and depressurization desorption under the conditions of normal temperature and low pressure.
