80Nm³/h 95% Purity VPSA Oxygen Generator for Aquaculture Pressure Swing Adsorption Oxygen Plant

In high-density aquaculture, dissolved oxygen levels are critical for the survival rate, growth speed, and breeding benefits of fish and shrimp. The VPSA oxygen generator (Vacuum Pressure Swing Adsorption Oxygen Generator) is the core equipment designed to overcome the "oxygen deficiency bottleneck." This professional pressure swing adsorption oxygen plant utilizes vacuum pressure swing adsorption technology to selectively separate air through molecular sieves, producing high-purity oxygen without chemical reagents. Compared to traditional oxygenation equipment, it reduces energy consumption by more than 40%. Specifically designed for aquaculture, this 80Nm³/h model with 95% purity can rapidly increase dissolved oxygen in water to 8-12mg/L, meeting the demands of high-density breeding for fish, shrimp, crab, and other species while minimizing risks such as "surface floating" and "pond turnover."

Traditional aquaculture oxygenation relies on equipment such as aerators and impeller oxygenators, achieving only 15%-20% oxygen dissolution efficiency from air. In contrast, the 95% high-purity oxygen produced by PSA oxygen systems can reach over 85% oxygen dissolution efficiency when used with nanobubble devices. For example, in an 80-mu grass carp aquaculture pond, traditional equipment requires 10 units of 15kW impeller oxygenators working simultaneously, while the 80Nm³/h VPSA oxygen generator requires only 35kW to maintain dissolved oxygen at 10mg/L. This not only saves 60% on electricity but also reduces stress responses in fish and shrimp, increasing growth rates by 12%-15%. Compared to standard PSA oxygen generators, the VPSA oxygen system reduces energy consumption through vacuum regeneration, making it ideal for long-term aquaculture operations.

The adjustable oxygen output design of this VPSA oxygen generator enables adaptation to multiple aquaculture scenarios. In pond aquaculture, it delivers oxygen directly to the bottom through floating aeration discs, solving bottom-layer oxygen deficiency. In industrial recirculating aquaculture systems, it integrates with ozone generators to enhance both dissolved oxygen levels and water purification. In shrimp and crab breeding farms, the 95% oxygen purity allows precise control of dissolved oxygen at 12mg/L, improving larval survival rates. Compared to VSA oxygen plants, this system maintains stable purity during low-power operation, making it suitable for intermittent high-oxygen-demand scenarios such as nights and rainy days while avoiding energy waste.

Oxygen generators for aquaculture must withstand high-humidity and salt-spray environments. Therefore, selecting experienced PSA oxygen generator manufacturers with aquaculture-specific design expertise is essential. Consider these three critical factors:

Additionally, prioritize manufacturers with proven cooperative cases with provincial aquaculture technology promotion stations to ensure compliance with technical specifications.

In conclusion, the 80Nm³/h 95% purity VPSA oxygen generator has revolutionized aquaculture oxygenation with its high efficiency, energy savings, and flexibility. Through pressure swing adsorption oxygen production technology, it effectively addresses oxygen deficiency in high-density aquaculture while providing controllable operating costs that enhance farmers' profitability, establishing it as an indispensable core component of modern aquaculture operations.
