How does the oxygen generator ensure stable and continuous oxygen supply in aquaculture?

The oxygen generator ensures stable and continuous oxygen supply for aquaculture through four core technical and design supports:

●PSA Technology's Continuous Cyclic Operation

Adopting mature Pressure Swing Adsorption (PSA) technology, the system is equipped with two parallel zeolite molecular sieve vessels. One vessel adsorbs nitrogen and impurities from compressed air to produce pure oxygen, while the other undergoes desorption (releasing adsorbed nitrogen) to regenerate. The seamless switch between adsorption and desorption cycles eliminates downtime, maintaining an uninterrupted oxygen output that matches aquaculture's 24/7 demand.

●Industrial-Grade Reliable Components

Key parts (compressors, valves, molecular sieves) are made of industrial-grade materials and undergo strict quality testing. They resist harsh aquaculture environments (high humidity, temperature fluctuations, salt spray for saltwater farms) and have a long service life. The robust build prevents sudden component failures that could disrupt oxygen supply.

●Intelligent Control & Automatic Adjustment

Equipped with intelligent control systems that monitor dissolved oxygen (DO) levels in water in real time. When DO drops below the set threshold (e.g., 5-6 mg/L for most aquatic species), the system automatically increases oxygen production flow; when DO is sufficient, it adjusts to a stable output. This closed-loop control ensures oxygen supply aligns with dynamic demands (e.g., feeding periods, high stocking density, or sudden temperature rises).

●Onsite Generation Eliminates External Dependencies

Onsite oxygen production avoids the risks of supply interruptions from external sources (e.g., delayed oxygen cylinder deliveries, liquid oxygen storage shortages, or transportation issues). The system only relies on ambient air and power, and with optional backup power compatibility, it can maintain operation even during short power outages, ensuring no gaps in oxygen supply.
