Key Features
Dual-Tower Adsorption Architecture: Employs twin-vessel pressure tanks packed with high-grade Zeolite Molecular Sieve (ZMS) to ensure uninterrupted gas separation cycles.
Automatic Purity Control (APC): Real-time Zirconia oxygen sensor continuously monitors purity; out-of-spec gas is automatically diverted and vented to protect patient safety.
Oil-Free Air Compression: Utilizes rotary screw air compressors paired with multi-stage refrigerant and desiccant dryers to eliminate oil and moisture ingress into the medical gas stream.
Redundant Back-Up Switchover: Automatically interfaces with secondary manifold systems (liquid bulk or high-pressure cylinder banks) during emergency shutdowns or scheduled servicing.
Data Logging & Audit Trail: Stores operational parameters (flow rate, delivery pressure, purity levels, and alarm logs) for 12 months to satisfy hospital regulatory audits.
Applications
Central Hospital Pipelines: Direct supply to Intensive Care Units (ICU), Operating Theaters (OT), Emergency Departments, and general wards via standard Medical Gas Pipeline Systems (MGPS).
Remote & Regional Clinics: Off-grid or geographically isolated healthcare facilities requiring independent, reliable medical gas infrastructure.
Emergency Field Hospitals: Containerized skid-mounted plants engineered for rapid deployment upon site utility connection.
Cylinder Filling Stations: Integrated high-pressure booster circuits designed for filling backup D, E, and J medical oxygen cylinders on-site.
Customization Options
Containerized / Skid-Mounted Enclosures: Weatherproof, thermally insulated ISO shipping containers equipped with industrial HVAC, internal lighting, and fire suppression systems for outdoor installation.
Multi-Compressor Lead-Lag Configuration: Dual compressor setups with automatic load sharing to ensure 100% redundancy and continuous uptime.
Seismic Reinforcement: Structural steel chassis calculations engineered to meet regional seismic zone compliance requirements.
Voltage Adaptation: Custom electrical integration tailored for non-standard local utility grids.
Manufacturing & Quality Control
Vessel Fabrication: Pressure vessels are welded using automated Submerged Arc Welding (SAW), followed by 100% Radiographic Testing (RT) and Ultrasonic Testing (UT) on critical structural seams.
Piping Cleanliness Standards: Medical-grade stainless steel (304/316L) distribution piping is chemically cleaned, degreased, and purged with high-purity nitrogen prior to assembly to eliminate hydrocarbon residues.
Factory Acceptance Testing (FAT): Every plant undergoes a mandatory 72-hour continuous full-load run test before dispatch, validating power consumption, gas purity stability, and acoustic performance.
Certifications & Compliance
ISO 13485: Certified Quality Management System for Medical Devices.
ISO 7396-1: Compliance framework governing medical gas pipeline systems.
CE Marked: Conforms to EU Medical Device Regulation (MDR) and Pressure Equipment Directive (PED).
ASME Section VIII: Pressure vessel design, construction, and stamping available upon request.
Packaging & Delivery
Modular Skid Shipping: Skid frames are securely bolted onto heavy-duty flatrack containers and sealed with waterproof, anti-corrosion barrier wrapping.
Containerized Units: Shipped as standard 20-foot or 40-foot High-Cube CSC-certified shipping containers, ready for direct crane offloading and on-site utility tie-in.
Comprehensive Documentation: Includes detailed P&IDs, electrical schematics, MTRs, FAT protocols, and localized operation and maintenance manuals.
FAQ
Q: What is the typical operational lifespan of the Zeolite Molecular Sieve (ZMS)?
A: Under strict feed air quality management (ensuring oil-free and dry air enters the adsorption towers), the operating life of the ZMS ranges from 8 to 10 years before replacement is required.
Q: How does the system respond to unexpected hospital power outages?
A: The PLC control system integrates directly with hospital emergency UPS circuits. Upon sudden power loss, automated emergency shut-off valves close immediately to preserve pipeline pressure while secondary reserve manifolds maintain uninterrupted supply.
Q: What are the space and structural requirements for a 100 Nm3/h plant?
A: A standard skid-mounted 100 Nm3/h system requires approximately 25 square meters of clean indoor floor space with a minimum ceiling clearance of 3.5 meters and a reinforced concrete floor capable of supporting the static equipment load.
