PSA Oxygen plant
Introduction
LDH Gas Systems Company Limited is a trusted manufacturer of PSA (Pressure Swing Adsorption) Oxygen Plants, delivering reliable and cost-effective oxygen solutions for industries, hospitals, and laboratories. Our non-high-purity PSA oxygen generators (90–95% O₂) are designed for applications where ultra-high purity is not required, offering an efficient alternative to traditional oxygen cylinders.
With ISO9001 and CE certifications, LDH combines advanced adsorption technology with robust engineering to ensure stable performance, low energy consumption, and minimal maintenance.
How It Works
The PSA Oxygen Plant separates oxygen from compressed air using a carbon molecular sieve (CMS) or zeolite adsorbent in a cyclic adsorption-desorption process:
- Air Compression: Ambient air is filtered and compressed.
- Purification: Moisture, oil, and CO₂ are removed via refrigerated dryers and filters.
- Oxygen Separation: The PSA system adsorbs nitrogen and other gases, allowing 90–95% oxygen to pass through.
- Storage & Distribution: Oxygen is stored in a buffer tank for immediate use or further purification if needed.

FAQ
Q: What's the oxygen purity range?
A: Standard systems deliver 90–95% O₂; higher purity (up to 99.5%) requires additional refining.
Q: How does PSA compare to VPSA or cryogenic plants?
A: PSA is more economical for small-to-medium capacities (<200Nm³/h), while VPSA suits larger volumes, and cryogenic plants offer ultra-high purity.
Q: Can the system integrate with existing pipelines?
A: Yes-our plants include buffer tanks and pressure regulators for seamless integration.
Q: What's the typical lifespan?
A: 10+ years with proper maintenance; adsorbent replacement every 5–8 years.
