Industrial PSA oxygen generators and VPSA-class systems with multi-bed vacuum desorption (MBVD™) — tonnage oxygen generators for mining, aquaculture, glass, and metals. Not medical oxygen generation systems.
Zenox supplies on-site oxygen production plants for industrial process duty. Our industrial PSA oxygen generators use zeolite molecular sieve for oxygen plant adsorption and MBVD™ multi-bed vacuum regeneration — a VPSA oxygen generator approach (vacuum pressure swing adsorption) aimed at energy-efficient regeneration and stable industrial purity. Specify a tonnage oxygen generator or skid package for mining leach/oxidation, aquaculture oxygenation, glass, metal cutting/welding, and process oxidation. U.S. commercial scope is industrial only: we do not sell medical oxygen generation systems, hospital PSA plants, or FDA device pathways.

How industrial PSA/VPSA oxygen works, why mines use tonnage plants, air quality, and what medical purity means (out of U.S. scope).
An industrial PSA oxygen generator compresses air, dries and filters it, then passes it through zeolite molecular sieve beds that preferentially adsorb nitrogen so oxygen-enriched product flows out; beds regenerate by depressurization and, in VPSA-class systems, vacuum-assisted desorption. Multi-bed equalization and vacuum steps improve recovery and lower the air factor versus simple two-bed cycles.
Mining and mineral processing use tonnage oxygen generators for continuous high oxygen flow—such as leach enhancement and process oxidation—where cylinder or liquid supply is logistically expensive or unreliable at remote sites. On-site oxygen production plants sized for industrial (not medical) purity deliver steady O₂ at the process rate without bulk tanker dependency.
Medical gas systems are regulated separately and typically require pharmacopeia-grade oxygen (often about 93% ±3% for many on-site medical PSA designs, or higher where specified by local code and device standards)—this is not Zenox USA’s product scope. Zenox USA supplies industrial PSA and tonnage oxygen generators for process plants only and does not offer medical oxygen generation systems or FDA device pathways.
Oxygen PSA plants require the same rigorous feed-air quality as nitrogen PSA: dry, particulate-free, and free of oil vapor, because zeolite molecular sieve for oxygen plant beds is damaged by moisture and hydrocarbons and oxygen-enriched systems raise fire risk if oil remains. Use oil-free compression or a full filtration and carbon-tower train before the generator.
Zeolite beds in industrial oxygen PSA are long-life consumables under clean feed air; replacement is condition-based (purity decline, pressure drop, contamination events) rather than a universal yearly schedule. Good pretreatment and oil-free practice extend zeolite life and protect VPSA/PSA performance.
Higher air factor means more compressed air—and more kWh—per ton or Nm³ of oxygen product. VPSA-class vacuum regeneration and multi-bed equalization are used on industrial oxygen generators specifically to improve recovery and reduce air factor versus conventional two-bed PSA.
Industrial oxygen users with steady high demand often save versus bulk liquid or cylinder supply by eliminating delivery margins and reducing stockouts, with savings scaling strongly with utilization and local bulk prices. Provide flow, purity, and operating hours for a project-level ROI discussion—not a one-size calculator.
Include flow, purity, pressure, materials, code, quantity, and drawings when available.
