50Nm³/h  PSA Oxygen Generator for Aquaculture Aeration vsa oxygen plant

PSA Oxygen Generator (Pressure Swing Adsorption Oxygen Generator) is an aquaculture aeration equipment based on Pressure Swing Adsorption (PSA) technology. It produces high-purity oxygen by separating air through molecular sieves, featuring core advantages such as stable flow rate, low noise (＜58dB), and low operating costs.

As a typical application of VSA oxygen plant, it requires no chemical reagents and can continuously supply oxygen with a purity of 90-93% to aquaculture ponds. It addresses the pain points of traditional aeration equipment, such as high noise and low aeration efficiency, and is particularly suitable for fish and shrimp farming scenarios sensitive to noise, making it a key equipment for improving quality and increasing yield in aquaculture.

In aquaculture, dissolved oxygen content directly affects the survival rate and growth rate of fish and shrimp. Traditional aeration methods (such as impeller aerators and blast aeration) have two major pain points: first, low aeration efficiency--oxygen in air accounts for only 21%, making it difficult to quickly increase dissolved oxygen; second, high noise (usually ＞70dB), which easily causes stress responses in fish and shrimp and reduces survival rates.

The oxygen with 90-93% purity produced by the PSA Oxygen Generator has an aeration efficiency more than 4 times that of air, which can quickly increase the dissolved oxygen in aquaculture ponds to 5-8mg/L (the suitable range for fish and shrimp). At the same time, its operating noise is ＜58dB, close to the ambient background noise, completely avoiding stress responses in fish and shrimp.

The flow rate of 50Nm³/h can cover 5000-10000㎡ of aquaculture water, suitable for small and medium-sized aquaculture ponds and industrialized aquaculture workshops. The core advantage of its PSA technology for oxygen generation lies in "on-demand oxygen supply". Through linkage control with dissolved oxygen sensors, the flow rate is automatically increased when dissolved oxygen is low, and automatically reduced when the standard is met. This not only ensures aeration effect but also saves energy consumption, reducing electricity costs by 30-50% compared with traditional equipment and significantly optimizing PSA oxygen plant cost.

When choosing a PSA Oxygen Generator, aquaculture farmers should focus on three core aspects: "aeration efficiency, noise control, and durability". In terms of aeration efficiency, priority should be given to equipment with oxygen purity ≥90% and flow rate matching the aquaculture scale, and suppliers can be required to provide test reports on dissolved oxygen improvement effects; in terms of noise control, it is essential to confirm that the operating noise is ≤60dB and inspect the equipment's operating noise on-site; in terms of durability, select PSA oxygen generator manufacturers with aquaculture industry cases and anti-corrosion design, requiring a warranty period ≥1 year and a warranty period of ≥2 years for core components (molecular sieves, fans).

In addition, customized functions can be selected according to the aquaculture mode. For example, industrialized aquaculture can add oxygen storage tanks to cope with sudden power outages; marine aquaculture can be upgraded to 316L stainless steel material to enhance salt spray resistance. Priority should be given to suppliers that can provide on-site installation and free training to ensure the rapid commissioning and standardized operation of the equipment.

With the advantages of low noise, high efficiency, and intelligence, the PSA Oxygen Generator has become an innovative solution for aquaculture aeration. The configuration of 50Nm³/h flow rate and ＜58dB noise accurately matches small and medium-sized aquaculture scenarios. Its pressure swing adsorption oxygen generator technology can create an optimal dissolved oxygen environment for the growth of fish and shrimp, helping aquaculture farmers improve quality, increase yield, reduce costs, and enhance efficiency.
