OGSI Leads the Way in Onsite Oxygen Technology for Aquaculture
Oxygen Generating Systems Intl. [OGSI] is the leading manufacturer of onsite oxygen generators. Using Pressure Swing Adsorption (PSA) technology, OGSI offers a complete line of oxygen generators and oxygen cylinder filling plants (CFP’s). They currently have oxygen plants in over 70 countries worldwide, serving many diverse markets including: fish farming (aquaculture) and ozone water treatment. The OGSI Aquaculture System is specifically designed for aquaculture applications and is efficient and cost-effective. It enables fish farms to dissolve oxygen in any size tank. Farms are able to increase stocking densities. The fish are also healthier and have better taste when raised in an oxygen rich environment. The investment in an oxygen system is typically recovered within two years meaning that the return on investment (ROI) is greater than 50% per year.

How it Works
A side stream of water from the raceway, pond or tank is pumped at elevated pressure through a venturi nozzle, where oxygen is injected. The water becomes saturated with oxygen and is then distributed through high velocity mixing nozzles along the bottom surface of the raceway, pond or tank. Oxygen flow rates can either be manually regulated or automatically controlled using a dissolved oxygen (DO) analyzer and probe. By ‘closing the loop’ with a signal that is fed back from the DO meter, the oxygen system can be turned on and off automatically, as needed. Dissolved oxygen (DO) is gaseous oxygen that is dissolved into water that fish directly absorb through their gills and skin for respiration. The DO concentration is measured in parts per million (ppm) and a saturation of 70% or concentration of 5 or 6 ppm is essential for stable growth in fish.
Systems Available
The OG-20 Oxygen Generator is a small and convenient ‘turnkey’ oxygen generating system. It is safe, dependable and easy to run. Its maintenance-free operation provides a quick way to meet your immediate oxygen needs. Larger models are available to suit the requirements of larger fish hatcheries and ponds. The larger models range from 25 SCFH to 5000 SCFH (5tpd). OGSI has a great deal of experience supplying oxygen to aquaculture facilities that raise a variety of fish species, among them trout, striped bass, tilapia and shrimp. The application engineers at OGSI can assess your facility’s operating needs and design an oxygen system to meet your specific needs. If oxygen is needed in cylinders for use in transportation or remote handling cylinder filling plants are available. These are systems that will immediately eliminate the high cost of delivered oxygen. No more spending valuable time changing and returning heavy oxygen cylinders. The CFP’s can automatically refill your oxygen cylinders for 24/7 availability and relieve you of your dependence on delivered oxygen. OGSI offers complete CFP’s, with capacities up to 500 cylinders per day. You can reduce your live haul expenses with these systems by filling your own cylinders.
Benefits of Installing an OGSI System:
- Increase stock density by maintaining a higher level of Dissolved Oxygen (DO)
- Produce larger quantities of high quality fish
- Increase reproduction rates
- Ensure the flavor of fish by providing a clean environment
- Prevent ice from forming during winter months
- Increase the oxygen content over a typical air-fed aerating system
- Ensure uniform DO levels throughout tanks and ponds
- Provide feed gas to an existing ozone generator for disinfection
