Aquaculture Frequency Inverter
Dedicated inverters for aquaculture are industrial control devices custom-engineered for core equipment such as aerators,water pumps,automatic feeders,and fans.Their core value lies in stabilizing water quality,reducing energy consumption,ensuring high survival rates,and facilitating easy maintenance and operation.By leveraging precise speed regulation and intelligent interlinking,these devices address the pain points of traditional aquaculture—namely,an over-reliance on empirical judgment and manual labor,coupled with high energy consumption—making them the essential hardware for smart aquaculture systems.
I.Core Functions and Technical Features
1.Scenario-Specific Control Logic
Dissolved Oxygen(DO)Closed-Loop Interlinking:Equipped with standard or optional DO sensors,the system automatically adjusts motor speed based on preset thresholds;when DO levels are low,the frequency increases to boost aeration;when DO levels are high,the frequency decreases to conserve energy.
Constant Pressure/Constant Flow Water Supply:Compatible with water pumps and circulation pumps,this feature stabilizes water flow and pressure within the aquaculture tanks,preventing issues such as tank scouring or water shortages.
Precise Speed​​Control for Feeders:Matches feeding rates to the specific dietary requirements of fish and shrimp at various growth stages,enabling quantitative,timed,and uniform feeding to minimize feed waste and water pollution.
Constant Pressure Control for Fans/Aeration Tanks:Compatible with aeration blowers and micro-pore aeration systems,this feature maintains stable air pressure within the tanks,thereby enhancing aeration efficiency.
2.Hardware and Environmental Adaptability
High Protection Rating:Features a standard IP65/IP66 rating(with an optional IP68 upgrade),offering robust protection against moisture,dust,and salt-mist corrosion,making it ideally suited for the humid environments found in fish ponds and processing workshops.
Wide Voltage Range and Anti-Interference:Supports a wide input voltage range(220V/380V)and features a built-in Class C3 RFI filter to minimize electromagnetic interference,ensuring stable operation even within complex power grid environments.
Weather-Resistant Design:Engineered to withstand high temperatures and high humidity,featuring reinforced circuit board coatings to extend the device's operational lifespan.
3.Intelligent and Communication Features
Multiple Communication Interfaces:Comes standard with RS485+Modbus RTU protocols,with optional support for 4G,Wi-Fi,Bluetooth,and Profinet,enabling remote monitoring and control via a dedicated mobile application.
Intelligent Protection:Incorporates a comprehensive suite of safety mechanisms—including protection against overcurrent,overvoltage,undervoltage,overheating,phase loss,permanent magnet demagnetization,and water immersion—to safeguard both the equipment and the aquaculture operation.Data Logging&Early Warning:Real-time recording of operating parameters,energy consumption,and fault information;triggers SMS or mobile app push notifications in the event of anomalies.
Momentary Power Loss Ride-Through&Energy-Saving Sleep Mode:In the event of a momentary grid power interruption,the system executes a controlled deceleration to prevent a complete shutdown;during periods of low load,it automatically enters a sleep mode to further conserve energy.
II.Compatible Equipment&Typical Scenarios
1.Core Compatible Equipment
Aerators:Impeller aerators,paddlewheel aerators,and aeration blowers(a primary application area,delivering 30%–50%energy savings).
Water Pumps:Submersible pumps,circulation pumps,and high-pressure flushing pumps(suitable for water circulation,water exchange,and cleaning operations).
Feeders:Automatic feeders(enabling precise,quantitative feeding to minimize feed wastage).
Fans/Blowers:Aeration blowers and ventilation fans(used to stabilize air pressure within aeration tanks).
2.Typical Application Scenarios
Pond Aquaculture:Ponds for rearing fish,shrimp,crabs,and shellfish;enables automatic regulation of dissolved oxygen levels to prevent fish mortality caused by oxygen depletion.
Industrialized Aquaculture:Recirculating Aquaculture Systems(RAS);facilitates precise control over water flow,dissolved oxygen,and temperature to support high-density farming operations.
Cage Culture:Offshore or lake-based cage systems;designed to adapt to complex hydrological conditions and maintain a stable aquatic environment.
Aquatic Feed Processing:Equipment such as extruders and mixers;enhances process stability and boosts production capacity.

Applications: Machine tools, textiles, hoisting, mining, packaging, plastics, chemicals, metallurgy, papermaking, conveying, petroleum machinery, fans and pumps, sewage treatment, HVAC, etc.
