PSA Oxygen Generator for Industrial Applications
An on-site ZMS twin-tower PSA oxygen generator for industrial duty: 93% ±3% O₂ at 1–200 Nm³/h, 0.4–0.5 MPa outlet and model-specific energy consumption.
This PSA oxygen generator produces oxygen at 93% ±3% purity on site using zeolite molecular sieve (ZMS) in a twin-tower pressure swing adsorption system.
Flow ranges from 1 to 200 Nm³/h with outlet pressure of 0.4–0.5 MPa and energy consumption confirmed for the selected model of oxygen produced, and the two towers alternate between adsorption and regeneration for a continuous supply.
The sieve separates oxygen from compressed air at the plant, so the oxygen does not have to be delivered and the supply can be sized to the actual duty.
It is used for aquaculture aeration, wastewater aeration, metallurgy enrichment and combustion enhancement; the standard range is not intended for direct respiratory medical use.

The PSA oxygen range is published as a purity and capacity configuration rather than a numbered model table: fix the required oxygen flow first, then confirm purity, outlet pressure and energy use for the duty.
- Adsorption towers: two adsorber vessels alternate between adsorption and regeneration, so the oxygen supply is continuous.
- Molecular sieve: zeolite molecular sieve (ZMS) selectively adsorbs nitrogen from the compressed air so oxygen passes through as product gas at 93% ±3% purity.
- Air dryer: the package includes an air dryer that brings the compressed-air moisture load down so the feed-air dew point requirement is met before the air reaches the sieve bed.
- Filtration: filtration stages remove oil aerosol and dust carried over from the compressor and receiver, protecting the sieve bed.
- Air receiver: a buffer tank (air receiver) between the compressor and the PSA towers steadies the feed-air supply.
- Control cabinet: PLC automatic control with an optional HMI touch screen; the control cabinet manages the valve cycle and the operating parameters.
- Purity monitoring: an oxygen analyser monitors the purity of the product oxygen, and its calibration is checked on schedule.
- Feed air: compressed air at model-specific pressure with a dew point of -40°C or lower, oil-free.
- Aquaculture aeration: supplies oxygen for dissolved-oxygen enrichment in fish and shrimp ponds.
- Wastewater aeration: provides oxygen for oxygen-enhanced aeration of the biological treatment stage.
- Metallurgy enrichment: enriches combustion air and supports oxygen enrichment in metallurgical processes.
- Combustion enhancement: raises the oxygen content of combustion air to improve combustion in furnaces and kilns.
- Glass manufacturing: applied to combustion efficiency improvement in glass production.
- Chemical oxidation: supports oxidation processes in chemical production.
- Cutting and welding support: supplies oxygen for metal cutting and welding support duties.
- Confirm the required purity and flow first, since these set the ZMS charge and the system size.
- Check the outlet pressure against the 0.4 to 0.5 MPa range and the energy consumption confirmed for the selected model when sizing power and operating cost.
- Confirm the feed-air supply is oil-free with a dew point of -40°C or lower, conditioned by an air dryer and filtration stages.
- Remember that standard PSA oxygen at 93% ±3% is not for direct respiratory medical use without certified medical-grade equipment.
- State the application, operating hours and installation conditions so the package can be sized as one system.
- Allow for start-up to rated purity of 30 minutes or less when planning the production schedule.
What purity does this PSA oxygen generator produce?
It produces oxygen at 93% ±3% purity using ZMS twin-tower PSA, with flow from 1 to 200 Nm³/h.
What is the energy consumption?
Energy use is approximately model-specific energy consumption of oxygen produced.
Where is 93% ±3% oxygen used?
For aquaculture aeration, wastewater aeration, metallurgy enrichment and combustion enhancement, plus glass manufacturing and chemical oxidation.
What outlet pressure is available?
Outlet pressure is adjustable from 0.4 to 0.5 MPa, with a feed-air requirement of model-specific pressure, dew point -40°C or lower and oil-free.
Is this oxygen suitable for medical use?
No. The standard 93% ±3% range is for industrial and aquaculture duty; direct respiratory medical use requires certified medical-grade equipment and the applicable local requirements.

How to Choose a PSA Oxygen Generator for Industrial Use
Quick answer: Industrial PSA oxygen is selected from purity, flow, outlet pressure and energy use. The standard ZMS twin-tower range is 93% ±3% O₂ at 1–200 Nm³/h, 0.4–0.5 MPa and model-specific energy consumption.
Which purity do industrial duties need?
The published range is 93% ±3% O₂, which covers aquaculture aeration, wastewater aeration, metallurgy enrichment, combustion enhancement, glass manufacturing and chemical oxidation. Higher-purity units cost more and are not required by these duties.
How do I compare running cost?
Use the published model-specific energy consumption of oxygen together with your electricity price and the duty hours; generating on site also removes liquid-oxygen delivery logistics. The PSA oxygen for aquaculture guide works through a typical comparison.
What does the system need from the site?
Compressed air at model-specific pressure, dew point -40°C or lower and oil-free, plus power and space for the skid, air dryer, filtration stages and air receiver.
