Product Description

The Permanent Magnetic Variable Frequency Impeller Aerator
The Permanent Magnetic Variable Frequency Impeller Aerator rotates the impeller driven by electric motor to agitate the water surface and stir gas and liquid films in order to expand gas-liquid interfacial area and accelerate the oxygen diffusion speed, aiming to increase the in-water-oxygen's concentration and gradient ultimately.
The impeller aerator forms an aerator-centered and oxygen-enriched circle with the radius of 10 meters in water. The pond test results showed that after running for 80 minutes, the level of dissolved oxygen and water temperature of 1.5 meters underwater is consistent with that of the upper water.
The impeller aerator improves water quality effectively and efficiently. For instance, solve hypoxia caused head floating of fishes and shrimps effectively, break down water stratification, increase stocking density, improve primary productivity of ponds, decrease feed coefficient, inhibit cyanobacteria blooms, purify the water, reduce CODcr and BOD5, remove nitrogen and phosphorus and break the ice.

Key Functions
Energy-Saving: The aerator uses high-efficient permanent magnet synchronous motor, which is more efficient and 30%-40% power savable compared to the traditional asynchronous aerator.
Variable Frequency: The revolution speed of the aerator can be automatically adjusted. Moreover, within a certain range of voltage the running speed is relatively stable while the grid voltage frequency jitters.
Stability: Enabled self-protection of phase loss, overload and short circuit to prevent malfunction.
Environmental Protection: Pollution-free with no gearbox to refuel for or routinely maintain for.
Light Temperature Rise: The temperature rise of aerator motor and controller owing to constantly working in summer is relatively lighter than that of traditional aerator, which extends product's lifespan.
Ultra-Quiet: The aerator applied advanced vector control algorithm eliminates electromagnetic and mechanical noise and works ultra-quietly.
High Waterproof Grade: With proved IPX7 waterproof grade, the machine can be fully immersed in water for over 300hs in working condition without water leakage and seepage.
Wide Voltage Operational Range: The aerator is adaptive to three-phase and single-phase voltage (200-400V, 110V-250V respectively) and safe to use under unstable grid voltage condition.
Easy Installation and Maintenance: Lightweight and easy installation, requires only one person to support installation underwater.
Intelligence Networking: Enabled operation (manually turn on and off), locating mechanical breakdown and specifying fault status real-time via WeChat.
