Medical PSA Oxygen Plant | On-Site Hospital Oxygen Generation System
The Medical PSA (Pressure Swing Adsorption) Oxygen Plant delivers a continuous, autonomous supply of medical-grade oxygen directly within healthcare facilities. By separating oxygen from ambient air via molecular sieve technology, the system eliminates reliance on external liquid oxygen deliveries and high-pressure cylinder logistics.
Engineered for continuous hospital operation, the plant integrates air compression, purification, adsorption separation, and automated control into a skid-mounted or containerized layout.

Key Features
Dual-Train Redundancy: Twin-tower adsorption vessels operate in alternating cycles, ensuring uninterrupted gas delivery 24/7/365.
Real-Time Purity Monitoring: Continuous electrochemical/zirconium dioxide sensors track oxygen concentration, dew point, and carbon monoxide traces, triggering immediate visual/audible alarms if parameters deviate from medical thresholds.
Automatic Venting Valve: Automatically purges sub-specification gas during startup or pressure drops to prevent unrefined gas from entering the hospital pipeline network.
Energy Optimization: Variable frequency drive (VFD) air compressors modulate power consumption based on real-time hospital consumption curves.
Applications
Central Hospital Pipeline Supply: Direct connection to main surgical suites, Intensive Care Units (ICUs), and emergency wards.
Operating Rooms & Trauma Centers: High-reliability primary gas source for anesthesia workstations and mechanical ventilators.
Remote & Field Healthcare: Autonomous oxygen generation for clinics lacking stable cryogenic liquid supply chains.
Customization Options
Containerized Enclosures: Weatherproof, sound-attenuated ISO shipping containers equipped with climate control, internal ventilation, and fire suppression for outdoor placement.
Backup Manifold Integration: Automatic changeover cylinder manifolds (High/Low pressure) integrated as a secondary fail-safe.
Remote Telemetry: Modbus/TCP, Ethernet, or 4G modules for remote diagnostics and integration into hospital Building Management Systems (BMS).
Manufacturing & Quality Control
Vessel Fabrication: Pressure vessels built in accordance with ASME Section VIII or EN 13445 standards, utilizing automated submerged arc welding and 100% radiographic weld inspection.
Piping Architecture: Medical-grade 316L stainless steel piping, chemically cleaned, degreased for oxygen service, and pressure-tested prior to dispatch.
Factory Acceptance Testing (FAT): Each system undergoes a continuous 72-hour full-load operational test, measuring gas purity, flow stability, and specific power consumption under simulated clinical loads.
Certifications & Compliance
ISO 13485: Certified Quality Management System for Medical Devices.
CE Marked: Complies with Medical Device Regulation (MDR) / Pressure Equipment Directive (PED).
ISO 8573-1 Class 1:2:1: Compressed air feed purity standard.
Packaging & Delivery
Modular Skid Shipping: Systems are pre-assembled on rigid structural steel skids, reducing on-site installation time to utility hookups.
Protection Standards: Openings are hermetically sealed with flanged covers; sensitive instrumentation is shock-mounted and vacuum-sealed in moisture-barrier foils for ocean transport.
FAQ
Q: How does the system handle power interruptions?
A: The system integrates with the hospital's emergency generator grid. The PLC controller features automatic restart protocols, re-establishing operating pressure and purging low-purity gas before reopening pipeline supply valves.
Q: What is the lifespan of the molecular sieve (zeolite)?
A: Under standard operating conditions with properly maintained feed-air filtration (free of oil and moisture), the ZMS (Zeolite Molecular Sieve) service life ranges between 20,000 to 30,000 operational hours.
Q: What routine maintenance is required?
A: Routine tasks include replacing compressor oil filters, line-filter elements, and
