Key Features
Dual-Tower Adsorption Architecture: Alternating adsorption and regeneration cycles driven by heavy-duty pneumatic valves ensure uninterrupted oxygen delivery.
High-Performance ZMS Filling: Packed with imported molecular sieves utilizing pneumatic vibration compaction to prevent channeling and dusting.
Auto-Purging & Waste Venting: Integrated purity analyzer automatically diverts substandard gas during startup or purity fluctuations, protecting downstream processes.
PLC Automation Suite: Siemens/Allen-Bradley PLC paired with a color HMI monitors pressure, purity, temperature, and valve cycles in real-time.
Applications
Metal Fabrication & Metallurgy: Oxygen enrichment for electric arc furnaces (EAF), cutting, and welding to increase combustion efficiency and lower fuel consumption.
Healthcare Infrastructure: Hospital central pipeline supply compliant with medical oxygen standards when paired with medical-grade filtration and oil-free compression.
Water & Wastewater Treatment: High-purity oxygen feed for biological reactors and ozone generation to accelerate organic pollutant breakdown.
Glass & Quartz Manufacturing: High-temperature burner assistance to raise flame temperature and accelerate melting rates.
Customization & Engineering Options
Containerized Enclosures: ISO standard steel containers equipped with HVAC, lighting, and sound insulation for extreme outdoor environments.
Redundant Compression Trains: Dual-compressor setups with automatic switchover for continuous 24/7 operations.
Remote Telemetry Module: Modbus/Profinet integration for SCADA systems and remote IoT diagnostic support.
Manufacturing & Quality Control
Fabricated utilizing automated cutting, CNC welding, and ASME-standard pressure vessel manufacturing processes.
Vessel Integrity: All adsorption towers undergo ultrasonic testing (UT), radiographic testing (RT), and hydrostatic testing at 1.5 times the design pressure.
Piping & Cleanliness: Stainless steel process piping is acid-cleaned, degreased, and pressure-tested to prevent particulate contamination of the molecular sieve bed.
Factory Acceptance Testing (FAT): Every system undergoes a 72-hour continuous trial run logging gas purity, flow stability, and power consumption prior to crating.
Certifications & Compliance
Quality Management: ISO 9001:2015 certified manufacturing processes.
Pressure Equipment: ASME Section VIII Div. 1 / CE-PED compliant pressure vessels.
Electrical Standards: UL/CSA certified control panels available upon request.
Packaging & Delivery
Secured Skid Structure: Heavy structural steel skids with lifting lugs and forklift pockets designed for ocean container shipping or flat-rack transport.
Corrosion Protection: Internal piping purged and sealed with inert gas; external surfaces sandblasted and coated with marine-grade epoxy paint.
Documentation Package: Includes P&ID diagrams, electrical schematics, material test reports (MTRs), and FAT certificates.
FAQ
Q: What is the typical lifespan of the Zeolite Molecular Sieve (ZMS)?
A: Under normal operating conditions with properly maintained feed air (oil-free and dry below -40 deg C dew point), the ZMS lasts between 8 to 10 years without requiring replacement.
Q: How does power consumption scale with oxygen purity?
A: Power consumption typically ranges from 0.38 to 0.45 kWh per Nm3 of pure oxygen, depending on the required output pressure and specified purity level (93% vs. 95%).
Q: What feed air preparation is required upstream?
A: The system requires an oil-free or heavily filtered lubricated screw compressor, a refrigerated air dryer, an activated carbon filter, and a desiccant air dryer to ensure inlet air relative humidity and hydrocarbon levels remain strictly controlled.
