Summits Medical Oxygen Generator system works on the principle of Pressure Swing Adsorption widely termed as PSA. This conventional gas separation technology is being used to separate Oxygen from Compressed air. The major components are a pair of adsorbent vessels. product tank, switching valves, intelligent PLC, Oxygen analyzer and instruments. The adsorbent vessels filled with Zeolite preferentially adsorbs nitrogen and CO, whereas Oxygen is not adsorbed by Zeolite due to its larger molecular size hence passes through the absorber and get stored in the product tank. Based on the prefixed time interval, the online adsorber switches to regeneration mode and Adsorbed gas from Zeolite is purged out to the atmosphere.
During this operation, Oxygen analyzer monitors the oxygen concentration. If oxygen concentration is less than the pre-set value, PLC switches the vent valve and purging out the impure gas till it reaches the required purity level. At the same time, hospital’s Oxygen demand will be met by a secondary source of supply (Cylinder/LMO) through alternative valve automatically.
