High-purity oxygen generator OXYBERG®

high-concentrationfor water treatmentfor aquaculture

Overview
On-site oxygen generation for fish farms and shrimp ponds to provide stable dissolved-oxygen levels, enable higher stocking densities and avoid liquid oxygen (LOX) deliveries. PSA (pressure swing adsorption) technology produces oxygen from ambient air by removing nitrogen, delivering a continuous and controllable oxygen supply. Designed for 24/7 operation. Made in Germany.

Key Benefits

• Stable dissolved oxygen for improved fish health, metabolism and feeding efficiency
• Enable higher stocking density and increased production output
• Continuous 24/7 supply with automatic adjustment to demand
• High-purity oxygen (typically 90–93 % O₂; configurable up to 95 %)
• Energy-efficient operation, low operating costs and minimal maintenance
• Compact, modular design for integration into ponds, tanks or RAS
• Automated oxygen control for precise regulation based on water conditions and biomass
• Reduces environmental impact by eliminating LOX transport

How it Works
PSA systems compress and pre-treat ambient air, then separate nitrogen using zeolite molecular sieves in alternating adsorption and desorption cycles. Oxygen-enriched gas is supplied directly to ponds, tanks or recirculating aquaculture systems (RAS). Advanced control systems modulate oxygen flow and purity to maintain target dissolved-oxygen levels.

Applications

• Fish farming and grow-out systems: maintain optimal DO and support growth
• Water quality management: support biological treatment and improve clarity
• Recirculating Aquaculture Systems (RAS): ensure stable oxygen distribution for filtration and bio-treatment
• Hatcheries and larviculture: precise oxygen control for larvae survival and healthy early-stage development
• Ecological restoration: oxygen injection for lakes, ponds and wetlands
• Research and conservation facilities: controlled supply for environmental simulation, breeding and rehabilitation

Advantages for Operators

• Reliable continuous supply reduces production risks and improves productivity
• Lower long-term costs compared with delivered LOX or cylinders
• Flexible system sizing and modular packages to match site-specific flow and purity requirements
• Supports sustainable intensification of aquaculture operations
