Produce oxygen where you need it

Oreco offers a wide range of oxygen generators. Choose from the extensive selection of standard solutions - or ask us to design a custom-made oxygen generator to match your needs. You will find the price surprisingly modest. All OrecoPSA generators are based on the Pressure Swing Adsorption (PSA) technology.

All OrecoPSA generators 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, Oreco can design a generator that fits your particular requirements.

A full installation comprises a compressor, a refrigeration dryer, filters, an air tank, a generator and a gas buffer tank. Naturally, you can have your full installation supplied by Oreco. But you can also buy each component and other optional supply such as high pressure compressors or filling stations separately. Smaller models are available with or without cabinets.
