What is an Industrial Oxygen Generator?
A PSA industrial oxygen generator produces oxygen on-site from atmospheric air using zeolite molecular sieves. The sieves selectively adsorb nitrogen under pressure, allowing oxygen to pass through at 90-96% purity. The system runs continuously on electricity alone. Absstem’s Idos delivers PSA oxygen at 1 to 5,000 Nm³/hr for steel, aquaculture, wastewater, and ozone applications.
Unlike medical oxygen systems built around pharmacopoeia-regulated purity, Idos is engineered for industrial process requirements – combustion efficiency, oxidation reactions, dissolved oxygen targets, and continuous-duty operation. No PESO licence is required for the generator itself.
For SMEs, MSMEs, and OEMs needing 1 to 100 Nm³/hr at 90 to 96% purity with plug-and-play setup, see Idos C – Absstem’s affordable industrial oxygen generator for small-scale businesses.

FAQs – Idos (Industrial Oxygen Generator)
What is the difference between a PSA oxygen generator and a PSA oxygen plant?
There is no technical difference between a PSA oxygen generator and a PSA oxygen plant. Both use PSA technology to generate oxygen on-site from atmospheric air. The term generator refers to the oxygen separation unit, while plant means the complete on-site system including compressors, storage, controls, installation, and commissioning. At Absstem, every PSA oxygen generator is delivered as a fully installed PSA oxygen plant.
What is an industrial oxygen generator used for?
An industrial oxygen generator is used to produce oxygen on-site for industrial processes such as steel and metal processing, aquaculture, wastewater treatment, pulp & paper, and ozone generation. It provides a continuous and reliable oxygen supply without dependence on cylinders or liquid oxygen.
How does a PSA oxygen generator work?
A PSA oxygen generator works by separating oxygen from compressed atmospheric air using zeolite molecular sieves. Nitrogen is adsorbed under pressure while oxygen passes through and is collected in storage tanks. The system operates in automated cycles to deliver continuous, on-site oxygen at the required purity, pressure, and flow for industrial applications.
Can Idos replace oxygen cylinders and liquid oxygen completely?
Yes. Idos is designed to act as the primary oxygen source for industrial operations.
It eliminates cylinder handling, storage risks, transport delays, and dependency on external oxygen suppliers while ensuring uninterrupted 24×7 oxygen availability.
What oxygen purity and flow does Idos provide?
Idos delivers standard oxygen purity of 90–96%. Flow capacities range from 1 to 5000 Nm³/hr, and each system is engineered based on actual process requirements.
How do industries select the right Idos capacity?
Idos capacity is selected based on oxygen flow demand, purity requirement, operating hours, and peak process load. Absstem’s engineers evaluate these parameters and design a customised PSA oxygen system to ensure stable purity, pressure, and long-term operational reliability.
What is the difference between Idos and MedO?
Idos is industrial (steel, aquaculture, wastewater, ozone). MedO is ISO 13485-certified medical oxygen for hospitals with pharmacopoeia-compliant purity and MGPS integration. For hospitals, see MedO instead.
What maintenance does Idos need?
Monthly filters, quarterly compressor service, annual dryer check, continuous IIoT sieve monitoring. Sieve warranty 10 years. AMC/CMC via Absstem Shield.
