Mentis PSA (Pressure Swing Adsorption) Oxygen Generators are advanced systems designed to enable efficient oxygen production directly at the point of use. By reducing dependence on cylinder and liquid oxygen supply, these systems deliver lower operating costs, greater supply security, and continuous oxygen availability for industrial and medical-related applications, depending on project scope and configuration.
At the core of Mentis PSA oxygen generators is high-performance Zeolite Molecular Sieve technology, which selectively adsorbs nitrogen from compressed air. The system operates with a synchronized twin-tower architecture:
Adsorption Phase: Conditioned compressed air is directed into the first tower. The zeolite adsorbent captures nitrogen, moisture, carbon dioxide, and certain unwanted components, allowing oxygen-enriched gas to pass through the system.
Regeneration Phase: Once the first tower reaches saturation, the system automatically switches to the second tower. The pressure in the first tower is then reduced, and the adsorbed gases are released to the atmosphere, preparing the tower for the next production cycle.
Continuous Oxygen Production: Through this PLC-controlled alternating cycle, the system provides a stable and uninterrupted oxygen flow to your facility 24/7.
To enhance performance and extend service life, Mentis engineering has developed Serial PSA (S-PSA) technology. This configuration integrates a twin-tower chemical drying and filtration stage containing activated alumina and activated carbon upstream of the main PSA towers.
Key benefits of S-PSA technology include:
Up to 15% Net Air Savings: Conventional systems using external desiccant dryers require additional purge air for regeneration. Mentis S-PSA technology utilizes the purge concept more efficiently within the integrated pre-treatment structure, helping reduce unnecessary compressed air losses and lower total operating costs.
System Safeguard and Zeolite Protection: The S-PSA towers act as a protective barrier for the sensitive zeolite beds inside the main PSA section. Moisture, oil vapor, and micro-particles are captured before reaching the oxygen generation stage, improving adsorbent life and protecting long-term system performance.
Improved Efficiency and Process Stability: Properly conditioned air entering the PSA columns enables more stable adsorption performance, better oxygen consistency, and a more reliable overall system.
Mentis PSA Oxygen Generators can be configured according to process requirements and typically deliver oxygen purity levels from 90% to 99,5%. For medical oxygen applications, the commonly targeted range is 95% ±1. Integrated analyzers allow continuous monitoring of oxygen purity.
Mentis PSA oxygen generators are suitable for a wide range of critical applications:
Hospitals and Medical Facilities: Reliable on-site oxygen supply for central oxygen systems.
Aquaculture and Fish Farms: Increasing dissolved oxygen levels to support fish health, productivity, and better water conditions.
