(I) Core Application Scenarios
MINNUO oxygen generators (PSA/VPSA oxygen-making equipment) are custom-designed for modern aquaculture. They are widely used in all types of aquaculture and high-density special breeding. Serving as core oxygenation equipment for factory recirculating aquaculture systems (RAS), large-scale pond farming, fry breeding and high-intensity raceway culture, they fully replace conventional impeller aerators, aeration devices and bottled liquid oxygen oxygenation solutions.
Conventional Pond Aquaculture
Suitable for low and medium-density farming ponds for fish, shrimp and crabs. The oxygen output flow can be precisely adjusted according to water area and stocking density to sustain high dissolved oxygen levels in water. It resolves common issues including oxygen depletion, aquatic organisms surfacing for air and total pond collapse on rainy days, nights and sweltering hot weather, maintaining stable oxygen supply for aquaculture water bodies.
High-Density Factory-Style Aquaculture
For indoor recirculating aquaculture (RAS), high-intensity raceway culture and intensive farming, the equipment delivers stable 24/7 oxygen supply to meet the high dissolved oxygen demands of high-density breeding. It allows farmers to double stocking density and supports large-scale, standardized aquaculture production.
Special Fry Breeding
Fry of fish, shrimp, shellfish, sea cucumbers and other special aquatic species have extremely strict requirements on dissolved oxygen precision. MINNUO oxygen generators consistently deliver high-purity oxygen at 93±3%, stably maintaining optimal dissolved oxygen conditions in water. This greatly boosts fry survival rates and lowers the occurrence of fry diseases.
Emergency Oxygen Replenishment for Harsh Conditions
In oxygen-prone environments such as hot summers, low-pressure rainy seasons, turbid water and eutrophic water bodies, the equipment rapidly replenishes oxygen and optimizes aquatic ecology. It suppresses the reproduction of anaerobic bacteria, improves water quality and prevents water body degradation.
(II) Core Industry Advantages
Stable High-Purity Oxygen Supply to Boost Aquaculture Output
Adopting advanced PSA/VPSA pressure swing adsorption oxygen generation technology, the equipment maintains steady oxygen purity between 90% and 95%. For high-precision scenarios such as fry breeding, stable purity above 93% can be achieved, far outperforming the aeration effect of traditional oxygenators. High-purity oxygen quickly raises dissolved oxygen levels in water, alleviates oxygen stress in aquatic creatures, accelerates fish and shrimp growth by over 20%, lifts overall survival rates by 20%–30%, and drastically increases per-unit aquaculture yield, enabling high-density, high-yield farming.
Intelligent Precision Oxygen Regulation, Adaptable to All Breeding Scenarios
Fitted with a PLC intelligent control system and AI data acquisition module, the unit monitors real-time key metrics including water dissolved oxygen, water temperature and stocking density. It dynamically adjusts oxygen generation frequency and output volume to achieve on-demand precise oxygen supply. The equipment supports unattended round-the-clock operation, with dedicated oxygen supply schemes tailored for low-density ponds, medium-to-high density intensive farming and factory fry rearing. It thoroughly eliminates pain points of traditional aerators such as uneven oxygen distribution, energy waste and delayed oxygen supplementation.
Ultra-Low Operating Costs for Energy Saving & Profit Growth
The generator takes atmospheric air as raw material, requiring no extra consumables or secondary raw material inputs. It operates pollution-free with zero emissions and only consumes electricity to produce oxygen continuously. It cuts energy consumption by over 25% compared with conventional oxygen supply methods; one kilowatt-hour of electricity generates 1 kilogram of oxygen. Additionally, the streamlined structure and stable pneumatic control lead to an extremely low failure rate, eliminating complicated daily maintenance. It significantly reduces long-term operation, maintenance and aquaculture medication costs, expanding profit margins for farmers.
Modular Design for Fast, Flexible Installation & Wide Compatibility
Built with skid-mounted and containerized modular structures, the equipment features a compact footprint and requires no large-scale civil construction renovations. It can be directly installed along pond banks, inside indoor aquaculture workshops and open-air farming bases for quick setup and commissioning, fitting upgrades for both new and existing aquaculture facilities. The unit runs under low pressure without risks of high-pressure gas cylinder storage, removing safety hazards associated with the transportation, storage and handling of bottled liquid oxygen, and improving overall aquaculture operational safety.
Improves Aquatic Ecosystem & Reduces Disease Rates
Consistent, precise oxygen supplementation enhances water microcirculation and accelerates the breakdown of harmful substances in water. It inhibits the accumulation of hydrogen sulfide, ammonia nitrogen and other toxic compounds and mitigates water eutrophication. Sufficient dissolved oxygen strengthens aquatic organisms’ immunity, sharply cutting cases of gill rot and hypoxia-induced illnesses, lowering aquaculture drug usage and supporting eco-friendly green farming.
FAQ
