Product Overview
The industrial PSA on-site oxygen production unit utilizes Pressure Swing Adsorption technology to separate 93% plus-minus 3% pure oxygen gas directly from ambient air. Engineered for continuous industrial and medical duty cycles, this skid-mounted system removes the operational costs and supply chain risks associated with high-pressure cylinder rentals and liquid oxygen bulk deliveries.

Key Features
Dual-Tower Adsorption Columns: Packed with high-capacity Zeolite Molecular Sieve (ZMS) to ensure uninterrupted gas output and consistent pressure stability.
Automatic Purity Control (APC): An integrated Zirconia oxygen analyzer monitors discharge purity in real time, automatically venting substandard gas before it enters the buffer tank.
Pneumatic Process Valves: Heavy-duty angle seat valves rated for greater than 1,000,000 switching cycles to minimize mechanical wear and maintenance intervals.
PLC Automation: Siemens S7-1200 controller paired with a 7-inch HMI touch screen; supports Modbus TCP/IP protocol for remote SCADA integration.
Energy Optimization Mode: Dynamic cycle adjustment matches actual downstream consumption, lowering power draw during partial-load operations.
Applications
Metal Fabrication: Laser cutting assist gas for carbon steel and stainless steel sheet processing.
Healthcare Facilities: Central pipeline oxygen supply for clinics and regional hospitals (complies with medical gas standards when paired with downstream medical purification packages).
Water Treatment: High-concentration feed gas for ozone generators used in municipal and industrial wastewater disinfection.
Glass Working: Torch fuel oxygen enrichment for ampoule sealing and quartz glass manufacturing.
Customization & Engineering Options
Containerized Oxygen Plants: ISO standard 20ft or 40ft shipping containers, fully insulated, equipped with HVAC, lighting, and ventilation for extreme outdoor climates.
High-Pressure Filling Systems: Integrated oil-free booster compressor and filling manifold for high-pressure cylinder charging (150 bar).
Ex-Proof Configuration: ATEX / Class I Div 2 electrical architecture designed for hazardous petrochemical plant installations.
Manufacturing & Quality Control
Our production processes are controlled to maintain strict mechanical integrity and long-term gas purity stability:
Vessel Fabrication: Pressure vessels are welded using automated SAW/TIG procedures, followed by 100% X-ray nondestructive testing (NDT) on all critical seam welds.
Surface Preparation: Carbon steel structural frames undergo abrasive grit blasting to Sa 2.5 standard, finished with a corrosion-resistant epoxy primer and polyurethane topcoat.
Factory Acceptance Testing (FAT): Every assembled unit undergoes a 72-hour continuous performance test at nominal flow and pressure. Leak verification is executed using mass spectrometer helium sniffer testing on all piping joints.
Certifications & Compliance
Quality Management: ISO 9001:2015 certified manufacturing facility.
Pressure Equipment Standards: ASME Sec. VIII Div. 1 stamping available; CE-PED compliance documentation for European markets.
Electrical Safety: UL/CSA compliant control panel components available upon request.
Packaging & Delivery
Export Packaging: Sealed in vacuum moisture-barrier foil with desiccants and secured inside fumigation-free wooden crating compliant with ISPM 15 standards.
Logistics Footprint: Skid dimensions are engineered to fit standard dry van containers or open-top shipping containers for efficient ocean freight handling.
Lead Time: Standard configurations: 3-4 weeks; Custom-engineered skid packages: 8-10 weeks.
Cost-Analysis: On-Site PSA vs. Liquid Oxygen Bulk Delivery
Evaluating capital expenditure (CAPEX) versus operational expenditure (OPEX) is critical for plant financial controllers. The comparative breakdown below outlines the economic impact:
|
Cost Factor |
Bulk Liquid Oxygen (LOX) Supply |
On-Site PSA Oxygen Production Unit |
|
Unit Gas Cost |
Subject to supplier price hikes, delivery fees, and minimum order quantities. |
Fixed baseline cost tied purely to local electricity rates (approx. 0.9 - 1.2 kWh/Nm3). |
|
Supply Chain Risk |
High exposure to road transit delays, driver shortages, and remote site access issues. |
Complete independence; gas is generated on demand inside your facility boundary. |
|
Boil-off & Vent Losses |
Inevitable atmospheric venting losses from cryogenic storage tanks during low-consumption periods. |
Zero storage loss; gas is produced dynamically according to real-time consumption. |
|
Financial Return |
Ongoing recurring operational expense with no asset retention value. |
Typical capital investment payback period ranges from 12 to 24 months depending on local cylinder/liquid rates. |
FAQ
Q: What is the operational lifespan of the Zeolite Molecular Sieve (ZMS)?
A: When supplied with clean, dry feed air (free of oil and liquid water via proper pre-filtration), ZMS lifespan exceeds 8 to 10 years without requiring replacement.
Q: How does ambient temperature affect unit capacity?
A: Nominal ratings are calculated at 20 deg C ambient temperature. Ambient temperatures exceeding 40 deg C require capacity derating calculations; specialized cooling packages are available for hot operational environments.
Q: What is the specific power consumption per cubic meter of oxygen?
A: Specific energy consumption ranges between 0.9 kWh/Nm3 and 1.2 kWh/Nm3, depending on the selected purity output and discharge pressure requirements.
