1.1 Oxygen Generation System Working Flow
1.2 ETR Oxygen Machine Description
Harnessing the cutting-edge PSA principles,
ETR medical PSA oxygen machine can
seamlessly produce 93%±3% purity oxygen gas directly from compressed air. In comparison with traditional bulk liquid oxygen and cylinder oxygen, this system
ETR on-site PSA oxygen machine can
remarkably reduce costs by up to 50%.
The compressed air undergoes a sophisticated purification process via an air dryer and precision filters, reaching optimal conditions for the main machine's operation. Integrated air buffers ensure a consistent flow of compressed air, minimizing fluctuations in the source. Our machine employs the time-tested PSA (pressure swing adsorption) technology, heralded for its efficacy in oxygen generation. Oxygen, meticulously purified to a desired 93%±3% standard, is efficiently stored in an oxygen buffer tank, ensuring a steady supply. The buffer tank maintains oxygen at a stable 4-bar pressure, guaranteeing reliability and quality.
