Hospital Oxygen Generator
Product Overview
This medical Pressure Swing Adsorption (PSA) oxygen generator system extracts medical-grade oxygen directly from ambient air. Designed for continuous on-site operation, it supplies stable oxygen pipelines for hospitals, clinics, and emergency medical facilities.
The system integrates air compression, purification, adsorption separation, and pressure regulation into a modular skid. It operates automatically based on pipeline pressure demand, removing dependence on liquid oxygen bulk deliveries and high-pressure cylinder logistics.

Dual-Train Redundancy Options:
Configured with dual compressors and parallel adsorption towers to eliminate single-point failure risks in critical care environments.
Automatic Purity Control (APC):
Real-time Zirconia oxygen analyzer continuously monitors purity; off-spec gas is automatically vented before reaching the medical pipeline.
Advanced Molecular Sieve Loading:
Utilizes high-density Zeolite Molecular Sieve (ZMS) with mechanical spring compaction to prevent powdering and channeling during cyclic pressure swings.
Oil-Free Screw Compression:
Medical-grade feed air compressors ensure zero hydrocarbon contamination in the feed stream prior to the PSA vessels.
Integrated Backup Manifold:
Seamlessly interfaces with secondary cylinder or liquid manifolds to satisfy NFPA 99 and ISO 7396 safety mandates.

fAQ
Q: What is the power consumption per cubic meter of oxygen?
A: Power consumption ranges from 1.1 kWh to 1.4 kWh per Nm3 of medical oxygen produced, depending on the required output pressure and ambient temperature.
Q: What is the lifespan of the Zeolite Molecular Sieve (ZMS)?
A: Under proper feed air filtration (maintaining oil and moisture levels below manufacturer thresholds), the ZMS operational lifespan exceeds 8 to 10 years without requiring replacement.
Q: How does the system handle power outages?
A: The system features an Uninterruptible Power Supply (UPS) for the PLC control and monitoring instrumentation. Upon power restoration, the system executes an automated purge cycle and safe restart sequence.
