Adsorbtech PSA Oxygen Gas Generator employs a compressor followed by a Compressed Air Treatment â€˜CATâ€™ Unit. The Adsorbtech CAT completes the first crucial step – generating clean, dry compressed air
Followed by the ‘CAT’ is the PSA Module. PSA Module consists of two Adsorption Towers interconnected with a set of auto operating valves. Each PSA tower contains specialized grade of Zeolite Molecular Sieves (ZMS) that adsorbs nitrogen molecules from compressed air. Now the PSA Tower is rich with pure Oxygen gas. The gas generating PSA Tower releases medical grade Oxygen gas to the Surge Tank.
While one tower vessel is in adsorption (Oxygen generation) cycle, the other is auto regenerating by depressurizing to the atmosphere, discharging the Nitrogen molecules. This regenerates the ZMS to adsorb Oxygen again. When the first vessel is saturated, the process direction is reversed.

Oxygen is a highly combustible gas and can cause instant fire hazards. Adsorbtech designs ensure highest safety measures are enforced to avoid oxygen gas leak from the equipment. User is advised to maintain the gas plant room with all necessary firefighting equipment.
Cylinder Oxygen/ Liquid Oxygen costs can be subject to huge variations during medical incidents (pandemic, epidemic) ; gas cylinder prices are subject to multi-fold inflation in such times. However, a PSA Oxygen plant will have fixed input cost i.e. power consumption. Average generation cost of Oxygen gas can be estimated at Rs. 10/Nm3 (Rs. 10 / 1000L). PSA generation also eliminates, or reduces, the cost of labour required to handle the volatile oxygen cylinders. Apart from finances, the most significant advantage is of the complete control the customer gains with On-Site Gas Generation. Additional advantage of lesser space requirement must also be factored into the economic advantages of On-site PSA oxygen gas generation.
The Adsorbtech PSA Oxygen Generator Series is designed and built to provide consistent gas supply to the user. However, power outages or maintenance activities can limit supply for a short period. Keeping oxygen cylinders may help avoid unwanted circumstances.
