PSA Oxygen Generator

The PSA Oxygen Generator is an on-site oxygen production system designed to deliver a reliable and cost-effective oxygen supply for industrial and process applications. Using pressure swing adsorption (PSA) technology, oxygen is generated by separating nitrogen from compressed air, providing a continuous source of oxygen without the need for cylinders or liquid supply.

PSA systems are widely used where consistent oxygen availability is critical for process control, efficiency and safety. In biogas applications, they are commonly used for controlled oxygen injection to support microbial desulphurisation, helping reduce hydrogen sulphide levels without significantly diluting the gas.

These systems can be configured to suit a wide range of flow rates and process requirements, with oxygen purity typically up to around 90–93%. Modular design allows systems to be scaled as demand increases, while integrated control options enable oxygen dosing to be linked to process variables such as gas flow or H₂S concentration.

PSA oxygen generators are a practical solution for sites looking to reduce operating costs, remove reliance on external gas supply and improve process performance through controlled oxygen delivery.
