Oxygen (O2) is used across a wide range of industries, from aquaculture to bioenergy, metallurgy, and pharmaceutical production. In the past, companies could only get oxygen from vendors. Now, however, there is a much better option for most of them: The on-site generation of oxygen. It allows professional users of oxygen users to become producers. Atlas Copco On-site gas generators are a reliable source of nitrogen and oxygen. On-site gas generation allows you to produce your own nitrogen or oxygen anytime you need. You can stop relying on third-party suppliers for your nitrogen or oxygen gas supply, make your own with one of our gas generators. An oxygen generator is a device that separates oxygen from compressed air using special selective adsorptive technology called pressure swing adsorption (PSA). The compressed air used in the oxygen generation process has a similar composition to ambient environmental air with 21% oxygen and 78% nitrogen. Oxygen for industrial use is generated by separating oxygen molecules from the other molecules within a clean, dry compressed air stream. Pressure Swing Adsorption (PSA) is a simple, reliable and cost-effective technology that enables continuous, high-capacity oxygen flow at the desired level of purity. Oxygen plants are industrial systems designed to generate oxygen. They typically use air as a feedstock and separate it from other components of air using pressure swing absorption or membrane separation techniques. Medical Oxygen Generators produce gaseous oxygen from compressed air on site and offer a cost-effective, reliable and safe alternative to traditional oxygen gas supplies such as cylinders or cryogenic liquid. An Oxygen Generator from Oxy wise, has been certified to European Directive 93/42/EEC on Medical Device.
