Produce oxygen where you need it

All major industries are under pressure to achieve results as efficiently, flexibly and reliably as possible. Oxygen is used in many industries and it provides a head start to produce it where it is needed. This is our specialty at Oreco.

Full installation or separate components

A full installation comprises:

  • Compressor
  • Refrigeration dryer

You can have a full installation supplied by Oreco or buy each component and other optional supply such as high-pressure compressors or filling stations separately. You can choose a standard solution or a custom-made generator to match your needs. We are here to contribute to your business.

Get in touch, tell us what you need
Our generators are based on the Pressure Swing Adsorption (PSA) technology and can be optimised to supply even higher purity – up to 95.0%. If you need a higher capacity, a high-pressure solution, higher purity or have other specific requests, we can design a generator that fits your particular requirements. Contact us to learn more.
