20L PSA Industrial Oxygen Generator | Reliable Oxygen Solution for High-Density Aquaculture

Technical Application

1. Working Principle
   The PSA oxygen generator adopts Pressure Swing Adsorption technology. Using zeolite molecular sieve to separate oxygen from ambient air, continuously supply high-purity oxygen without liquid oxygen or oxygen cylinder transportation.
2. Core Parameter (20L Model)
   Oxygen flow rate: 20 L/min
   Oxygen concentration: 90%±3%
   Continuous 24-hour non-stop operation
   Stable outlet pressure, compatible with microbubble mixer, venturi and pipeline aeration system.
3. Typical Application Scenarios

• Indoor Recirculating Aquaculture System (RAS)
• High density shrimp, tilapia, grouper, lobster farming
• Hatchery, fry breeding workshop
• Emergency oxygen supplementation for intensive fish ponds

4. System Matching Advantage
   Can be directly connected to RAS filtration, protein skimmer and disinfection units. Increase dissolved oxygen (DO) in aquaculture water, accelerate organic matter decomposition, inhibit anaerobic bacteria growth, improve water quality stability.

1. Reduce mortality rate
   Sufficient dissolved oxygen reduces fish and shrimp stress, avoids hypoxia outbreaks. Mortality can be reduced by 8%–15% in intensive farming.
2. Accelerate growth cycle
   Good oxygen environment promotes feed digestion. Feed conversion ratio (FCR) improves, shorten harvest cycle, realize more batches of cultivation within one year.
3. Cut long-term oxygen cost
   On-site air-to-oxygen production eliminates repeated purchases of oxygen cylinders or liquid oxygen. Compared with bottled oxygen, operating cost can be saved by 40%–65% annually.
4. Support higher stocking density
   Stable oxygen supply allows higher breeding density, maximizing output within the same pond area and increasing total annual revenue.
5. Lower water exchange frequency
   Optimized water oxygen level slows water quality deterioration, reduces water pumping and wastewater treatment expenditure.
