PSA Oxygen System for Aquaculture in Indonesia
An on-site PSA oxygen system was configured for shrimp-pond dissolved-oxygen enrichment. The reported system delivered 40 Nm³/h of oxygen at 93% purity.
Project Approach
This project is documented from the reported operating data below. For a comparable duty the required flow, purity or head, pressure, temperature, medium properties and operating schedule are confirmed first, then the equipment family and configuration are selected against those values.
Reported Scope and Duty
Reported for this installation: application — Shrimp aquaculture, oxygen flow — 40 Nm³/h, purity — 93%. These are the figures reported for this project and are not a guarantee for other sites.

How a Similar Project Is Specified
Send the application and the required capacity first. The configuration is then fixed against the duty point, the operating environment (indoor or outdoor, ambient temperature, power supply) and the applicable site or regional requirements. Where a purity, pressure or flow is not yet fixed, the achievable range is confirmed before equipment is proposed.
Frequently Asked Questions
What oxygen purity do I need for aquaculture?
93% ±3% O₂ from a standard ZMS twin-tower PSA unit is suitable for aeration. Higher-purity (99.5%+) units cost more and are unnecessary for aquaculture.
How is a PSA oxygen generator sized for a pond?
Estimate demand from biomass, feed rate and water temperature using 0.5–1.0 kg O₂ per kg of feed as a starting point, then size at about 1.25 times average demand with a small liquid-oxygen top-up.
