Containerized & Skid-Mounted Medical Oxygen Supply Station
The Medical Oxygen Supply Station is a turnkey PSA (Pressure Swing Adsorption) plant engineered for continuous hospital pipeline distribution and high-pressure cylinder filling. Utilizing Zeolite Molecular Sieve (ZMS) to extract medical-grade oxygen (93% +/- 3%) from ambient air, the system provides an autonomous gas supply for healthcare facilities, eliminating reliance on liquid oxygen (LOX) deliveries in remote or infrastructure-limited regions.

Key Features
Dual-Train Adsorption: Twin-tower configuration operates on automated cyclical pressure equalization to ensure continuous, pulse-free gas delivery.
Automatic Purity Purging: Real-time electrochemical sensors continuously monitor oxygen purity; sub-specification gas is automatically isolated and vented before reaching hospital networks.
PLC Automation & BMS Integration: Siemens S7-1200 PLC manages automated valve actuation, cycle timing, and fault logs, featuring Modbus TCP/IP communication for central hospital monitoring.
Oil-Free Feed Compression: Industrial rotary screw compressors combined with multi-stage coalescing filters and activated carbon towers prevent hydrocarbon contamination.
Applications
Central Hospital Infrastructure: Primary source for surgical suites, ICUs, and general inpatient wards.
Field & Emergency Hospitals: ISO-containerized layout enables rapid overland transport and plug-and-play commissioning in disaster relief or remote clinics.
Regional Cylinder Filling Hubs: Integrates high-pressure boosters to fill standard 40L medical cylinders at 15 MPa concurrently for satellite clinics.
Customization Options
Enclosure Types: Weatherproof, insulated ISO steel containers for outdoor placement, modular skids for indoor plant rooms, or soundproof acoustic hoods.
Climatic Adaptations: Tropical ambient packages rated for continuous operation up to 50 C, and winterization heating systems for sub-zero environments.
Backup & Redundancy: Automated switchover interfaces designed to interface with secondary cryogenic LOX tanks or high-pressure backup manifolds.
Manufacturing & Quality Control
Piping Systems: Medical-grade 316L stainless steel distribution piping undergoes chemical cleaning, acid passivation, and degreasing for oxygen service, verified by high-purity nitrogen pressure testing.
Factory Acceptance Testing (FAT): Every assembled station undergoes a 72-hour continuous full-load run test to measure net flow output, specific power consumption, purity stability, and emergency shutdown sequence verification prior to crating.
Certifications & Compliance
Quality Management: ISO 9001 and ISO 13485 (Medical Devices Quality Management Systems).
Regulatory Framework: CE certified under the EU Medical Device Regulation (MDR); fully compliant with ISO 7396-1 (Medical gas pipeline systems) and ISO 10083 (Oxygen concentrator supply systems).
Packaging & Delivery
Export Crating: ISPM 15-compliant heat-treated wooden crates or sea-fastened containerized blocks engineered for secure global maritime transit.
Moisture & Contamination Defense: Flanged pipe openings are sealed with blind flanges and gaskets; silica gel desiccants are secured inside electrical control cabinets to prevent humidity damage.
Lead Time: Standard configurations ship within 45 - 60 business days from technical drawing approval and deposit receipt.
FAQ
Q: What is the operational lifespan of the molecular sieve, and what maintenance does it require?
A: Zeolite Molecular Sieve (ZMS) performance relies on dry, oil-free feed air. With proper compressor filtration and auto-drain maintenance, the sieve lifespan exceeds 40,000 operational hours (approx. 7 to 8 years).
Q: Can the system interface with our existing hospital Building Management System (BMS)?
A: Yes. The PLC control cabinet provides standard dry contacts and Modbus communication ports (RS485/Ethernet) to transmit system faults, purity levels, and operating pressures directly to central nurse stations or BMS terminals.
Q: What site infrastructure is required for installation?
A: A level reinforced concrete pad with adequate overhead clearance, industrial 3-phase power supply, and ambient ventilation. No external water utility connections are required.
