Details

The 200 LPM PSA Oxygen Generation Plant is a fully automated, energy-efficient system that produces 93±3 percent pure medical oxygen onsite using Pressure Swing Adsorption (PSA) technology. It eliminates the need for oxygen cylinders, ensuring a continuous and cost-effective supply for hospitals, ICUs, and oxygen therapy units. Equipped with a screw-type air compressor, twin-tower PSA unit, multi-stage filtration, and PLC-based automation, it offers low maintenance, real-time monitoring, and quick installation. The system meets Global Medical Standards, ISO 8573 Class 4 norms, and global safety regulations.

Working Principle – PSA Technology
The 200 LPM PSA Oxygen Generation Plant functions using Pressure Swing Adsorption (PSA), a method that selectively separates oxygen from nitrogen using Zeolite Molecular Sieves. The plant operates through a continuous adsorption and regeneration cycle.
1. Compressed Air Supply – Ambient air is compressed, dried, and filtered to remove moisture, oil, and dust particles.
2. PSA Oxygen Separation – The clean compressed air is passed through Zeolite Molecular Sieves, which adsorb nitrogen, allowing oxygen to pass through.
3. Regeneration Cycle – When the first PSA tower reaches nitrogen saturation, the system automatically switches to the second tower, while the first tower releases nitrogen into the atmosphere and regenerates.
4. Continuous Oxygen Flow – The system operates in a cyclic manner, ensuring an uninterrupted supply of medical-grade oxygen at 200 LPM capacity.
