Product Description

PSA Oxygen Generator

Our standard products are often modified or customized to meet specific customer requirements. During more than 10 years in business, we have exhibited an unprecedented level of growth and excellence in China. Our customers use our gas systems to replace or augment other gas delivery methods, and many report monthly savings of up to 60%.

Our oxygen system pioneered the adoption of PSA technology. The PSA oxygen (up to 93-95% purity) systems are widely used in kinds of industries.
It is our privilege to be able to design and build systems that save protect the environment, and offer simple, cost-effective solutions to our customers.

Our standard, economically priced oxygen generation systems can be customized as needed.

The new type of oxygen generators can be integrated with a compressor and oxygen cylinder filling station in a box structure for easy shipping and on-demand, low-cost oxygen generation.

The extra oxygen can be stored up in the tank and the oxygen generator will stop running when the tank is filled. This intermittent working mode contributes to cool the equipment and increase its service life.


I. Adopting German technology, the oil-free compressors ensure adequate supply of source air with large air output
II. Using CECA medical grade molecular sieve and advanced packaging technology, the oxygen concentration can reach up to 90% purity without decay after 5 minutes
III. Dual cooling system is designed to improve the performance of the heat dissipation in an all-weather condition.
IV. The concentration monitoring technology has been developed to monitor the oxygen concentration on line
V. Multi-grade noise reduction devices are integrated and the noise is less than 50 db

VI. With the multiple early-warning systems such as pressure-low warning, failure warning, overload and concentration errors warning, the equipment is safe and reliable
VII. Maintenance-free operation

We can give our customers timely feedback on the problem encountered by our customers with on-site generators.

1. Built-in oil free air compressor

2. Built-in refrigerated air dryer

3. High efficiency PSA oxygen generate unit

4. Oxygen concentration: 90%±2

5. Pressure of oxygen outlet: ≤0.1 MPA

6. Control: Door lock, Ammeter, Work indicator, Power indicator, On/Off button, Oxygen flow meter, Voltmeter, Oxygen outlet, Fuse, Power input

RAS Process

RAS Water Treatment Processes

A series of treatment processes is utilized to maintain water quality in intensive fish farming operations. These steps are often done in order or sometimes in tandem. After leaving the vessel holding fish the water is first treated for solids before entering a biofilter to convert ammonia, next degassing and oxygenation occur, often followed by heating/cooling and sterilization. Each of these processes can be completed by using a variety of different methods and equipment, but regardless all must take place to ensure a healthy environment that maximizes fish growth and health. 

Drum Filer

Be used for the Solids Filtration

Able to remove 42%~75% of the total particales from the aquaculture water vlume.


Be used for the Oxygenation

High performance&durable, with high oxygen utilization rat

Specialized design for high density farming.
