Product Description
In high-density aquaculture, the dissolved oxygen level directly determines 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 to break through the "oxygen deficiency bottleneck". As a professional **pressure swing adsorption oxygen plant**, it is based on vacuum pressure swing adsorption technology, which separates air selectively through molecular sieves and produces high-purity oxygen without chemical reagents. Compared with traditional oxygenation equipment, its energy consumption is reduced by more than 40%. This 80Nm³/h model with 95% purity is specially designed for aquaculture. It can quickly increase the dissolved oxygen in water to 8-12mg/L, perfectly meeting the high-density breeding needs of fish, shrimp, crab and other species, and fundamentally reducing the risks of "surface floating" and "pond turnover".

Why is the VPSA Oxygen Generator More Efficient Than Traditional Oxygenation Equipment?
Traditional aquaculture oxygenation relies on equipment such as aerators and impeller oxygenators, with an oxygen dissolution efficiency from air of only 15%-20%. However, the 95% high-purity oxygen produced by the **psa system for oxygen** (Pressure Swing Adsorption Oxygen System) can reach an oxygen dissolution efficiency of over 85% through nanobubble devices. Taking an 80-mu grass carp aquaculture pond as an example, traditional equipment requires 10 units of 15kW impeller oxygenators to work simultaneously, while the 80Nm³/h VPSA oxygen generator only needs 35kW to stabilize the dissolved oxygen in water at 10mg/L. It not only saves 60% of electricity but also reduces the stress response of fish and shrimp, increasing their growth rate by 12%-15%. Compared with the **psa oxygen generator** (Pressure Swing Adsorption Oxygen Generator), its **VPSA Oxygen System** reduces energy consumption through vacuum regeneration, making it more suitable for the long-term operation needs of aquaculture.
Adapting to Different Aquaculture Scenarios: Flexible Application from Ponds to Industrial Systems
The adjustable oxygen output design of this VPSA oxygen generator enables it to adapt to multiple aquaculture scenarios: in pond aquaculture, it can deliver oxygen directly to the bottom of the water through floating aeration discs, solving the problem of oxygen deficiency in the bottom layer; in industrial recirculating aquaculture, it links with ozone generators to not only improve dissolved oxygen but also assist in water purification; in shrimp and crab breeding farms, the 95% oxygen purity can accurately control the dissolved oxygen in the breeding pond at 12mg/L, improving the survival rate of larvae. Compared with the **vsa oxygen plant** (Vacuum Swing Adsorption Oxygen Plant), it can still maintain stable purity during low-power operation, making it suitable for intermittent high oxygen consumption scenarios such as nights and rainy days, avoiding energy waste.
Key to Selection: Choose Aquaculture-Specific **PSA Oxygen Generator Manufacturers**
Oxygen generators for aquaculture need to adapt to high-humidity and salt-spray-rich environments. Therefore, it is necessary to select **psa oxygen generator manufacturers** (PSA Oxygen Generator Manufacturers) with experience in aquaculture scenario design. Three key points should be checked during selection: first, whether the equipment uses corrosion-resistant materials, and whether the components in contact with oxygen and water are made of 316 stainless steel to avoid seawater corrosion; second, whether it is equipped with a dissolved oxygen linkage control system that can automatically adjust oxygen production according to real-time dissolved oxygen data, reducing manual operation; third, after-sales response capability, requiring manufacturers to have service outlets in aquaculture-concentrated areas to ensure on-site maintenance within 4 hours in case of equipment failure. In addition, priority should be given to manufacturers with cooperative cases with provincial aquaculture technology promotion stations to ensure the equipment complies with aquaculture technical specifications.
In conclusion, the 80Nm³/h 95% purity **vpsa oxygen generator** has completely transformed the oxygenation model in aquaculture with its advantages of high efficiency, energy saving and flexibility. Through **pressure swing adsorption for oxygen production** (Pressure Swing Adsorption Oxygen Production Technology), it not only solves the oxygen deficiency problem in high-density aquaculture but also improves farmers' benefits with controllable operating costs, becoming an indispensable core equipment in modern aquaculture.
