Twin-Tower PSA Oxygen Generator - OXYPURE®

Compared to our Modular PSA Oxygen Generators, the OXYPURE® Twin-Tower PSA Oxygen Generators from NOXERIOR are able to cover larger oxygen consumptions.

These Twin-Tower systems are designed for heavy-duty operation, where system availability in combination with low running costs are primary objectives.

The key features of the OXYPURE® Twin-Tower PSA Oxygen Generators are:


  • High Reliability
    Low gas speeds through the molecular sieve beds, first-class components, stainless steel valve bodies and process piping, heavy-duty industrial PLC. Manufactured to work. Always.

  • Lowest Energy Consumption
    Energy cost is your major expense, not depreciation. Fast pay-back assured. Let OXYPURE® help you lower costs.

  • Easy Installation
    Easy installation and integration with existing equipment: All system tie-in points are on one side.

  • Compact Dimensions
    Limited height and minimum footprint to reduce transport costs. The largest OXYPURE® oxygen generators OS-100x3 and OS-100x4 will be supplied as turn-key installed systems on a transport frame.

  • Customisation
    An extended list of options allow you to define your specific OXYPURE® Twin-Tower PSA Oxygen Generator adjusted to your individual requirements;
