Industrial Oxygen PSA Plant
An Industrial Oxygen PSA Plant separates oxygen from compressed ambient air using Pressure Swing Adsorption technology. Utilizing high-grade Zeolite Molecular Sieves (ZMS), the system selectively adsorbs nitrogen under pressure to continuously deliver gaseous oxygen at purities ranging from 93% to 95%.
Engineered for continuous 24/7 industrial and medical operations, this modular skid-mounted system eliminates liquid oxygen logistics dependencies, reducing long-term operational gas costs. Successfully deployed in over 200+ industrial sites and medical facilities globally across North America, Europe, and Southeast Asia.

FAQ
Q: What is the primary operational cost factor for a PSA oxygen plant?
A: Electrical power consumption required to drive the feed air compressor represents the majority of operating expenses. Our systems maintain a specific energy consumption benchmark of approx. 0.9 to 1.1 kWh/Nm3 of pure oxygen, delivering up to 40% to 60% operational savings compared to bulk liquid oxygen (LOX) delivery models.
Q: What is the expected service life of the Zeolite Molecular Sieve (ZMS)?
A: Under proper feed air quality management (maintaining oil-free and moisture-free conditions via refrigerated and desiccant dryers), ZMS lifespan exceeds 5 to 8 years before requiring top-up or replacement.
Q: How does the system handle fluctuating oxygen demand?
A: The PLC monitors receiver tank pressure. When downstream demand drops, the system automatically shifts to standby or reduces cycle frequency, lowering power draw proportional to actual consumption.
