Mentis PSA (Pressure Swing Adsorption) Nitrogen Generators are advanced systems engineered to produce industrial-grade, high-standard nitrogen gas directly on-site at your facility. Eliminating dependency on external suppliers as well as cylinder and liquid nitrogen purchasing costs, these generators are designed to deliver maximum energy efficiency and optimum performance.
At the core of Mentis nitrogen generators is premium Carbon Molecular Sieve (CMS) technology. The system operates with a synchronized twin-tower architecture:
Adsorption Phase: Conditioned compressed air is directed into the first tower. The CMS material traps oxygen, carbon dioxide, and moisture molecules within its microporous structure, allowing high-purity nitrogen gas to pass through the line.
Regeneration Phase: As the first tower reaches saturation, the system automatically switches to the second tower. During this process, pressure in the first tower is reduced and the retained oxygen and other gases are vented to the atmosphere for regeneration.
Continuous Production: Thanks to this PLC-controlled cyclic process, a stable and uninterrupted nitrogen flow is supplied to your facility 24/7.
To maximize generator performance and service life, Mentis engineering has developed the groundbreaking Serial PSA (S-PSA) technology. Going beyond conventional systems, this design incorporates an integrated twin-tower chemical drying and filtration system containing activated alumina and activated carbon, positioned ahead of the main PSA towers.
Key advantages of S-PSA technology include:
15% Net Air Savings: Conventional systems using external desiccant dryers typically consume around 15% purge air for regeneration. Mentis S-PSA technology uses the purge air already utilized in the PSA process within its integrated chemical dryer as well, eliminating this waste entirely. Compared to conventional alternatives, this results in up to 15% air savings and significantly reduces compressed air operating costs.
System Safeguard and CMS Protection: The S-PSA towers act as a protective barrier for the sensitive Carbon Molecular Sieve beds in the main PSA towers. Moisture, oil vapors, and micro-particles are captured before they can reach the PSA section, protecting the CMS material and extending system life.
Enhanced Efficiency and Cooling: Compressed air passing through the pre-filtration and drying stages is cooled to optimal levels before entering the PSA towers. This fully conditioned and cooled air maximizes adsorption efficiency and elevates the overall performance of the Mentis nitrogen generator.
Mentis PSA Nitrogen Generators can be calibrated according to your specific process requirements and are capable of producing nitrogen at purity levels ranging from 90% up to 99.9995%. Thanks to integrated oxygen analyzers, gas purity is continuously monitored.
Designed for critical industrial operations requiring high reliability, Mentis nitrogen generators deliver superior performance across a broad range of industries:
Laser Cutting and Metal Processing: Supply of high-pressure, high-purity assist gas for burr-free, smooth surface quality and oxidation-free cutting.
Food and Beverage Industry (MAP): Extending shelf life and preserving freshness in Modified Atmosphere Packaging applications by preventing oxidation.
Electronics and Semiconductor Manufacturing: Providing a stable inert atmosphere that minimizes dross formation in lead-free wave and reflow soldering processes.
Petrochemical and Chemical Industry: Reliable inerting and blanketing of tanks, pipelines, and reactors to minimize combustion and explosion risks.
Pharmaceutical Industry: Creating a dry and stable environment during the production and packaging of sensitive active ingredients.
