IDOS – Industrial Oxygen Generator

Discover the absolute reliability for your industry with on-site oxygen generator

How is Industrial oxygen produced with PSA?

Absstem’s industrial oxygen generator uses only atmospheric air as raw material. Industrial oxygen generator consists of two adsorbers filled with zeolite molecular sieves. Pressurized air is passed through one of these adsorbers, zeolite having a structure to attract nitrogen, adsorbs nitrogen from air and oxygen is allowed to pass through to the storage tank and is produced as the final product. As adsorber approaches saturation, air is allowed to pass through the other adsorber while this adsorber is being regenerated to ensure a continuous supply of medical oxygen. This changeover takes place through a specially designed micro controller to ensure a hassle free operation. The quality of oxygen produced is continuously monitored by an oxygen analyzer.

Data control and logging

For audits and certifications, the oxygen purity data, running hours of air compressor and filters etc. can be traced, displayed or stored in a chip and can be exported to an external device.

Multistage filtration system

  • We recommend special multistage filtration system to protect the ZMS from oil and dust particles.
  • Additional filters drain moisture using an ADV (Automatic Drain Valve)

Designed for tough weather conditions

  • Industrial Oxygen machines show longevity in a dust/moisture-free environment
  • Ergonomic design, robust structure and advanced HMI makes it an efficient oxygen producer

Automatic start-up

  • Minimum pressure valve with bypass nozzle for a fast start-up
  • Eliminates the risk of overflow and ZMS damage

Premium energy efficiency

Air factor (air-to-Oxygen ratio) from 1.8 (95% O2)

The most complete scope of supply

  • Oxygen flow meter as standard
  • Zirconia oxygen sensor with a long lifetime
