VPSA Oxygen Generator is an oxygen production equipment adopting vacuum pressure swing adsorption technology. It sends air into adsorption towers through blowers, and after selective separation of nitrogen by molecular sieves, oxygen with a purity of 90%-95% is output from the top of the towers. When adsorption reaches saturation, vacuum pumps are used to evacuate and regenerate molecular sieves. The entire set of equipment operates automatically with convenient operation and strong environmental adaptability, and can be applied to multiple scenarios such as iron and steel smelting and sewage treatment.

Salient Features
Full Automation
All systems are designed for un-attended operation and automatic Oxygen/Nitrogen demand adjustment.
Lower Space Requirement
The design and Instrumentation makes the plant size very compact, assembly on skids, prefabricated and supplied from factory.
Fast Start-up
Start-up time is about 30 minutes to get desired Oxygen purity. So these units can be switched ON & OFF as per Oxygen/Nitrogen demand changes.
High Reliability
It's very reliable for continuous and steady operation with constant Oxygen/Nitrogen purity. Plant availability time is better than 90% always.
UOP Molecular Sieves Life
Expected UOP Molecular Sieves life is more than 10-years i.e. whole life time of Oxygen plant. So no replacement costs.
