High-Purity Oxygen PSA System Product Page
The Industrial High-Purity Oxygen PSA (Pressure Swing Adsorption) Generator separates oxygen from ambient air using high-grade Zeolite Molecular Sieves (ZMS). By selectively adsorbing nitrogen under pressure, the system continuously delivers high-purity oxygen gas at the point of use. Engineered for 24/7 continuous industrial and medical operations, it eliminates the logistics, safety hazards, and recurring expenses associated with liquid oxygen dewars or high-pressure cylinder delivery.

Key Features
Automated Purity Control: Integrated zirconia oxygen analyzer continuously monitors output. An automatic vent valve instantly purges out-of-spec gas to protect downstream processes.
Low Specific Energy Consumption: Optimized bed aspect ratio and high-efficiency switching valves reduce power consumption to 0.42 - 0.48 kWh/Nm3.
Heavy-Duty Process Valves: Pneumatic valves rated for over 1,000,000 switching cycles without maintenance.
Dual-Tower Adsorption Structure: Pressure equalization piping minimizes internal pressure shocks, extending molecular sieve lifespan beyond 6 years.
Industrial Automation: Siemens / Allen-Bradley PLC control system featuring remote Ethernet access, real-time trend logging, and comprehensive fault diagnostics.
Applications
Metal Fabrication: Oxy-fuel cutting, laser cutting auxiliary gas support, and welding.
Healthcare Facilities: Centralized hospital pipeline supply (meets ISO 10083 standards when integrated with medical purification skids).
Aquaculture: High-density fish farming and oxygen enrichment in RAS (Recirculating Aquaculture Systems).
Environmental & Chemical: Wastewater treatment aeration and ozone generation feed gas.
Customization & Regional Compliance Options
Containerized Skids (Containerized Oxygen Generator): ISO standard 20ft or 40ft containers, insulated, climate-controlled, and pre-wired for outdoor installation.
Booster Systems: Oil-free piston or diaphragm oxygen boosters for cylinder filling up to 150 bar.
Electrical Design Standards: NFPA 70 / NEC compliant panels, NEMA 4X enclosures, or ATEX explosion-proof ratings for hazardous operational zones.
Filtration Skids: Multi-stage filtration incorporating activated carbon and sterile filters for medical or food-grade applications.
Manufacturing & Quality Control
Vessel Fabrication: Pressure vessels designed and manufactured per ASME Section VIII Div. 1 or GB150 standards. Automatic submerged arc welding (SAW) with 100% radiographic testing (RT) on seam welds.
Sieve Loading Technology: Dense-packing method utilizing mechanical vibration to eliminate internal dead zones and prevent molecular sieve pulverization.
Factory Acceptance Testing (FAT): Every system undergoes a 72-hour continuous full-load run test. Pressure boundary integrity is verified via helium mass spectrometry leak testing.
Certifications & Compliance
Quality Management: ISO 9001:2015 certified manufacturing facility.
Regional Directives & Standards: CE Marked (Machinery Directive 2006/42/EC, PED 2014/68/EU).
Project-Specific Compliance (North America): Available with third-party verification or custom engineering support for ASME pressure vessel standards and UL/CSA compliant electrical components based on project requirements.
Welding Certification: Welders qualified to EN ISO 9606-1 / ASME Section IX.
Packaging & Delivery
Export Crating: Fumigation-free wooden crates or sea-worthy shrink-wrapped container securing.
Component Protection: Flanges sealed with blind covers; delicate instruments removed and packed in anti-static shockproof foam.
Lead Time: Standard modular units ship in 4 to 6 weeks. Custom engineered systems require 8 to 12 weeks.
FAQ
Q: What is the expected operational lifespan of the molecular sieve?
A: Under strict operating conditions (feed air oil content < 0.01 mg/m3 and dew point <= -40 C), the Zeolite Molecular Sieve operates effectively for 6 to 10 years without replacement.
Q: Can the system adjust output flow automatically based on fluctuating demand?
A: Yes. The PLC control adjusts cycle times automatically to match actual gas consumption, minimizing power usage during partial load operation.
Q: What utility requirements are necessary on-site?
A: A stable 3-phase electrical power supply, a cooling water source or adequate ventilation for the air compressor, and a leveled concrete foundation.
