01
Operating principle
Compressed air passes through adsorption media that preferentially retain nitrogen during one stage of the cycle. Alternating vessels allow oxygen-enriched gas to be produced while the media regenerate.

PSA Oxygen Generators
Produce oxygen on site for normal demand, peak support or backup strategy.
PSA oxygen generators separate oxygen from compressed air to provide an on-site oxygen source. Marine Blue integrates PSA systems for oxygenation, high-density culture and backup applications where the project duty and operating strategy justify them.
Selection and design considerations

Normal and peak oxygen demand
02
Required oxygen concentration and pressure
03
Ambient conditions and air quality
04
Compressor and dryer requirements
05
Storage and buffer capacity
06
Redundancy and external backup
07

Final capacities, materials, dimensions and operating limits are confirmed against the current model datasheet and project duty point.
02
Role in the system
The generator is one part of an oxygen system that may also include air preparation, receiver or buffer storage, oxygen-quality monitoring, distribution piping, dissolution equipment, alarms and emergency supply.
03
Applications
- RAS facilities
- Indoor shrimp and fish production
- Hatcheries and nurseries
- Live holding
- Oxygen backup and peak-demand support
04
Integration requirements
Coordinate the PSA package with oxygen cones, injectors or other transfer devices; storage; distribution; pressure regulation; analyzers; controls; alarms; ventilation and emergency oxygen. Oxygen-compatible materials and procedures are essential.
05
Operation and maintenance
The plan should cover compressors, filtration, dryers, adsorption vessels, valves, analyzers, cooling, ventilation and scheduled service. Operators must understand alarm conditions and the transition to backup supply.
06
Customer value
On-site generation can reduce dependence on delivered oxygen for defined operating conditions and create a controllable supply source. Economics, reliability and capacity require project-specific assessment.
