PSA Oxygen Generation Technology

On-Site Medical-Grade Oxygen Generation

Reliable, high-purity oxygen generation eliminates cylinder logistics while providing consistent supply for ozone systems, medical applications, and industrial processes. Manufactured at our world-class facility in Chennai, India.

The Science of On-Site Generation

Pressure Swing Adsorption (PSA) Technology

PSA technology uses zeolite molecular sieves to selectively adsorb nitrogen from compressed air, allowing high-purity oxygen to pass through. Dual adsorber vessels cycle between adsorption and regeneration phases, enabling continuous production.

This proven process delivers 90-95% purity oxygen on-demand using only ambient air as feedstock — no chemicals, no cylinders, no supply chain dependency. A critical enabler in the Lotus Tech Stack for maximising ozone system performance.

Why Choose On-Site Oxygen Generation?

Eliminate cylinder dependency with reliable, cost-effective oxygen production

Medical Grade Purity

Delivers 90-95% pure oxygen suitable for medical, aquaculture, and ozone generation applications

Lower Lifecycle Cost

Eliminates cylinder delivery, storage, and handling costs with on-demand generation

Reliable Continuous Supply

Uninterrupted oxygen supply for critical applications with >95% system uptime

Enhanced Ozone Yield

High-purity oxygen feed increases ozone generation efficiency by 2-3x vs air feed

Automated Operation

Self-regulating systems require minimal operator intervention and maintenance

Environmentally Safe

No chemical processes or hazardous materials — uses only ambient air as feedstock

PSA Generation vs Cylinder Supply

See why leading industries are switching from cylinder logistics to on-site PSA generation

Industry Reality: Cylinder-based oxygen supply chains are expensive, unreliable, and create significant safety hazards with high-pressure vessels. For any operation consuming more than a few cylinders per week, on-site PSA generation delivers a faster ROI — typically under 2 years — while ensuring uninterrupted, worry-free supply.
