Modular Hospital Oxygen Plant (PSA System)
Engineered for continuous medical-grade oxygen supply, this modular PSA (Pressure Swing Adsorption) hospital oxygen plant is a fully integrated, skid-mounted or containerized system. It extracts oxygen from ambient air on-site, fulfilling ISO 13485 and ISO 7396-1 standards for direct hospital pipeline distribution.
Product Overview
The system integrates air compression, purification, PSA oxygen generation, and gas stabilization into a single modular framework. Built for rapid deployment, it eliminates logistics and installation bottlenecks associated with traditional liquid oxygen bulk tanks or cylinder manifolds, ensuring complete supply independence for healthcare facilities.

Key Features
Dual-Tower Adsorption Architecture: Utilizes high-grade Zeolite Molecular Sieve (ZMS) with automated pneumatic switching valves to maintain stable cyclic pressure and continuous flow output.
Integrated Filtration Train: Removes moisture, oil aerosols, and particulates down to 0.01 um upstream of multidimensional adsorption vessels to prevent molecular sieve contamination.
Automatic Purity Purging: Real-time Zirconia oxygen analyzer continuously monitors output purity; sub-specification gas is automatically vented before entering the hospital pipeline.
Plug-and-Play Skid Layout: Piping, valves, and electrical wiring are pre-assembled on a structural carbon-steel skid, requiring only external power and pipeline connection on-site.
Applications
Primary Hospital Supply: Main medical gas source for operating theaters, ICU wards, and emergency departments.
Remote & Rural Clinics: Off-grid or remote healthcare facilities lacking reliable liquid oxygen delivery infrastructure.
Emergency Field Hospitals: Rapidly deployable containerized units for disaster relief and military medical deployments.
Hospital Capacity Expansion: Modular augmentation to supplement existing central oxygen manifold networks.
Customization Options
Containerized Climate-Controlled Enclosure: ISO maritime container outfitted with thermal insulation, industrial HVAC climate control, and integrated fire suppression systems for severe outdoor environments.
Redundant Backup Integration: Automated switchover manifold for high-pressure backup cylinders.
Multi-Compressor Configuration: N+1 compressor redundancy setups for high-availability clinical environments.
Dual-Line Output: Simultaneous supply of low-pressure pipeline gas (0.5 MPa) and high-pressure cylinder filling (15 MPa).
Manufacturing & Quality Control
Our production facility operates under strict medical device manufacturing protocols:
Vessel Fabrication: Pressure vessels are welded using automated submerged arc welding, followed by mandatory ultrasonic and X-ray non-destructive testing (NDT) adhering to ASME/GB standards.
Piping & Cleansing: Medical-grade stainless steel pipelines undergo acid pickling, passivation, and ultrasonic degreasing to eliminate hydrocarbon residues prior to oxygen service.
Factory Acceptance Testing (FAT) Protocol: Every plant undergoes an exhaustive 72-hour continuous full-load run test. Each unit is individually tested for design flow rate capacity, dew point control, specific power draw, and real-time purity stability under simulated peak clinical loads. Full performance logs are archived and provided in the shipment documentation.
FDA Compliance Alignment: Built in accordance with current Good Manufacturing Practice (cGMP) guidelines for medical gas equipment manufacturing, ensuring full traceability of components and strict process validation documentation for international regulatory submissions.
Certifications & Compliance
Quality Management: ISO 13485 (Medical Devices), ISO 9001.
Safety & Standards: CE compliant (Medical Device Regulation / Pressure Equipment Directive), ISO 7396-1 (Medical gas pipeline systems).
Traceability: Material test reports (MTRs) provided for all pressure vessels, valves, and molecular sieves.
Packaging & Delivery
Corrosion Protection: Exposed ports sealed with blanking flanges; internal circuits and electronics moisture-sealed with desiccants.
Shipping Configurations: Skid units shipped in open-top high-cube containers; containerized plants shipped directly as standard ISO shipping containers.
Documentation Package: Includes Piping and Instrumentation Diagrams (P&ID), electrical schematics, FAT reports, and maintenance manuals in English.
FAQ
Q: What is the expected lifespan of the Zeolite Molecular Sieve (ZMS)?
A: Under normal operating conditions with proper feed-air filtration and oil-free compression, the ZMS lifespan ranges between 20,000 to 40,000 operational hours before replacement is required.
Q: How does the system handle power interruptions?
A: The PLC control system features uninterruptible power supply (UPS) backup for monitoring instruments. Upon power restoration, the system initiates an automated purge sequence before resuming normal pipeline supply.
Q: What maintenance is required on a routine basis?
A: Routine maintenance involves replacing compressor air filter elements, coalescing filter cartridges, and drain valve seals every 2,000 to 4,000 operating hours.
