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. Zeolite Molecular Sieve Oxygen Plant Main Features

• Stable oxygen purity ensuring qualified clinical oxygen usage
• Issuing alarm signal against abnormal parameters,the system detects the moisture content of the compressed air in real time on line
• Onliine oxygen monitor,remote monitoring system
• LCD touch screen interface, making setting of operating parameters more convenient

3.Zeolite Molecular Sieve Oxygen Plant Working Principles

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.
