Large-Capacity Hospital PSA Oxygen Generator
The Large-Capacity Hospital PSA (Pressure Swing Adsorption) Oxygen Generator is an on-site medical gas generation system engineered for continuous, high-volume oxygen supply in healthcare facilities. By separating medical-grade oxygen from ambient air via high-efficiency Zeolite Molecular Sieve (ZMS), the system feeds directly into the hospital's central pipeline network at regulated operating pressures. It is fully compliant with ISO 7396-1 and HTM 02-01 standards for centralized medical gas pipeline systems (MGPS).

Key Features
Continuous Dual-Tower Adsorption: Alternating dual-vessel cycles maintain steady, uninterrupted pressure and flow without drops during bed regeneration.
Automatic Purity Purging: Integrated pneumatic valves automatically vent sub-specification gas during startup or pressure anomalies, protecting hospital pipelines.
Dynamic Load Adaptation: PLC algorithms adjust cycle timings based on real-time clinical consumption, minimizing power draw during off-peak hours.
Medical-Grade Filtration Train: Multi-stage filtration removes moisture, particulate down to 0.01 micron, and hydrocarbon traces to prevent pipeline contamination.
Redundant System Architecture: Dual-compressor options and parallel bank configurations eliminate single-point-of-failure risks for critical care infrastructure.
Typical Applications
Central Hospital Pipelines: Primary supply source for intensive care units (ICU), neonatal care (NICU), operating theaters, and general wards.
Field & Emergency Hospitals: Skid-mounted modular configurations deployed rapidly for emergency surge capacity or remote infrastructure.
Hyperbaric Oxygen Therapy (HBOT): Stable, high-flow continuous oxygen delivery for multi-place hyperbaric chambers.
Customization Options
Containerized / Skid-Mounted Build: Pre-assembled ISO marine containers or open structural steel skids for outdoor placement or constrained mechanical rooms.
Backup Supply Integration: Automatic switchover manifolds linking system outputs to high-pressure cylinder ramps or liquid oxygen (LOX) reserve tanks.
Environmental Conditioning: Tropicalized compressor options, heavy-duty air-drying trains, and ambient temperature regulation for extreme regional climates.
Manufacturing & Quality Control
Vessel Fabrication: Pressure vessels constructed via automated submerged arc welding (SAW), subjected to 100% radiographic testing (RT) and hydrostatic testing per ASME/GB codes.
Piping Integrity & Degreasing: 304/316L medical-gas grade stainless steel piping, strictly chemically degreased for oxygen service, argon-arc (TIG) welded, and pressure-tested for 24 hours.
Factory Acceptance Testing (FAT): Each system undergoes a mandatory 72-hour continuous endurance run testing purity stability, flow output, and electrical fail-safes prior to crating.
Certifications & Compliance
Quality Management: ISO 13485 (Medical Devices Quality Management Systems), ISO 9001.
Regulatory Compliance: CE compliant (Medical Device Directive / MDR pathway), ISO 7396-1 (Medical gas pipeline systems), Pharmacopoeia standards (USP/EP oxygen purity compliance).
Packaging & Delivery
Corrosion & Moisture Protection: Internal components sealed with nitrogen purging; exterior coated with marine-grade anti-corrosion primer and enamel.
Transport Crate Build: Fumigation-free plywood crating with internal shock-absorbent anchoring, or secure container lashing for safe international maritime freight.
Standard Lead Times: Standard configurations ship within 30 to 45 days; custom containerized engineering systems require 60 to 75 days.
FAQ
Q: How does the system respond to a sudden facility power outage?
A: The control cabinet integrates with the hospital's emergency generator grid. If system pressure drops below safety margins, an automatic emergency shutoff valve isolates the pipeline while activating backup cylinder manifolds.
Q: What is the expected service life of the molecular sieve?
A: Maintained with stable feed-air dryness (pressure dew point below -40 degrees C), the Zeolite Molecular Sieve operates continuously for 8 to 10 years without requiring material replenishment.
Q: Can the system interface with the hospital's central BMS?
A: Yes. The HMI is equipped with standard Modbus TCP/IP communication ports and optional Ethernet/4G gateways for direct connection to hospital Building Management Systems.
