PSA Medical Oxygen Generator

Medical Oxygen Generator

Oxygen is an important part of human life. Our atmosphere consists of 21% Oxygen. Even though normal human beings can survive with this atmosphere, critical patients require higher concentrated and pure Oxygen. The higher concentrated oxygen can be produced with few processes including cryogenic and pressure swing adsorption. Summits Medical Oxygen Generators use a process called PSA which is a simple and economical process which can be adapted on site and concentrated Oxygen (as per World Health Organization (WHO) norms) can be produced as and when required without hazzles. Summits Hygronics is also a certified ISO 13485 firm (Medical Device Quality Management)


PSA Oxygen Generator works on the principle of Pressure Swing Adsorption, which is being used to separate Oxygen from the Compressed air.

The major components of Summits Medical Oxygen Generator are a pair of Adsorbent vessels, Surge tank, Switching valves, Intelligent PLC, Oxygen analyzer, and instruments. The adsorbent vessels of Summits Medical Oxygen Generator are filled with Zeolite which preferentially adsorbs Nitrogen and CO2 whereas
Oxygen is not adsorbed by Zeolite due to its larger molecular size and passes through the Adsorber to the surge tank. Based on the pre-set time interval of Summits medical oxygen generator the online adsorber switches to generation mode and adsorbed gas from Zeolite are purged out to the atmosphere. During this operation Oxygen analyzer which is a standard scope of Summits medical oxygen generator monitors the oxygen concentration and if the oxygen concentration is lower than the pre-set value, the PLC switches on the vent valve and purges out the gas till it reaches the required purity level. At the same time the hospital Oxygen demand will be automatically met through the standby valves and secondary source of Oxygen.
