Idos – Industrial Oxygen Generator for On-Site PSA Oxygen Production
Absstem’s Idos Industrial Oxygen Generator is a PSA-based on-site oxygen generation system designed for industries that require continuous, reliable oxygen without dependence on cylinders or liquid oxygen supply. Idos is supplied as a fully engineered, installed and commissioned PSA oxygen system, delivering oxygen directly to your process at the required purity, pressure and flow.
It is widely deployed in steel and metal processing, aquaculture, pulp & paper, wastewater treatment, and ozone generation, where oxygen quality and uptime directly affect production efficiency and operating cost.
What is an Industrial Oxygen Generator?
An industrial oxygen generator is a system that produces oxygen on-site from atmospheric air using Pressure Swing Adsorption (PSA) technology. It replaces oxygen cylinders and bulk liquid oxygen by providing continuous, on-demand oxygen directly to industrial processes. Idos is Absstem’s industrial-grade PSA oxygen generator, designed for heavy-duty, 24×7 plant operation.
How PSA Oxygen Generator Works
Air Intake & Purification
Ambient air is filtered, dried and compressed.
PSA Oxygen Separation
Zeolite molecular sieves adsorb nitrogen, allowing oxygen to pass through.
Oxygen Storage & Delivery
Oxygen is stored in buffer tanks and supplied to the process pipeline.
Automated Control
Automation with IIoT monitoring ensures stable purity and low operating cost.
Typical Performance of PSA Oxygen Plant
| Parameter | Idos Capability |
|---|---|
| Oxygen Purity | 90–96% (up to 99.5% available on demand) |
| Oxygen Flow | 1 to 1000 Nm³/hr |
| Delivery Pressure | 5.5 barg (higher pressures available on demand) |

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%, with higher purity levels up to 99.5% available on demand. Flow capacities range from 1 to 1000 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.
