VSA Oxygen Generator

The VSA Oxygen Generator is a high-capacity oxygen production system designed for applications requiring larger oxygen flow rates and improved energy efficiency. Using vacuum swing adsorption (VSA) technology, oxygen is produced by separating nitrogen from air at low pressure, with vacuum regeneration of the adsorbent material.

VSA systems are particularly suited to larger-scale installations, where continuous oxygen demand and operating efficiency are key considerations. In biogas applications, they are commonly used for oxygen dosing in larger anaerobic digestion plants, supporting microbial desulphurisation and gas quality improvement.

Compared to PSA systems, VSA technology can offer lower energy consumption at higher flow rates, making it an effective solution for sites with sustained oxygen demand. Systems are designed for continuous operation and can be integrated with process controls to regulate oxygen supply based on real-time conditions.

VSA oxygen generators provide a dependable and efficient alternative to delivered oxygen, supporting long-term cost savings and improved process control across industrial and renewable energy applications.
