This fan is a digital, intelligent, and energy-efficient product, primarily composed of a DC brushless external-rotor motor (EC motor) and a high-efficiency centrifugal impeller. Via an electronic controller, it enables precise regulation of rotational speed, airflow, and pressure, effectively reducing energy consumption and operating noise while substantially improving efficiency and extending service life.
Industrial EC Internal-Rotor Axial Fan (Heavy-Duty Precision Cooling)
Designed for high-load environmental control, demanding thermal management, and continuous green energy optimization, our EC Internal-Rotor (Inrunner) Axial Fan Series couples a high-torque brushless DC inrunner motor with an aerodynamically contoured axial impeller. Featuring superior motor heat dissipation and enhanced ingress protection, this series excels in high-resistance, long-duty applications where structural durability and precision speed control are paramount.
Fully compliant with European ErP Directive (EU 327/2011) energy standards and CE / LVD / EMC regulations, it is the ideal solution for precision cooling, heavy HVAC systems, and outdoor energy infrastructure.
Smart Electronics & Superior Inrunner Thermal Management
Robust Inrunner Motor Construction: The internal rotor design allows the motor stator housing to sit directly in the airflow or external heat sink, providing significantly superior cooling for the motor itself compared to outer-rotor alternatives. This ensures longer bearing life and continuous full-load operation in high-ambient environments.
Precision Digital Modulation: Integrated smart onboard electronics support 0–10V DC, PWM, and Modbus RTU (RS485) communication protocols, enabling dynamic closed-loop speed regulation based on system temperature and pressure feedback.
Energy Savings & Low Noise: High-efficiency EC technology reduces power consumption by up to 30%–50% compared to traditional AC fans while lowering operational acoustic levels.
Targeted High-Duty Applications
Data Centers & IT Infrastructure: In-row cooling units, Computer Room Air Handlers (CRAH), and high-static server hall ventilation.
Energy Storage & Inverters (BESS & PCS): Containerized Battery Energy Storage Systems, high-power solar inverters, and transformer cooling modules.
Telecom & Electronic Cabinets: Outdoor 5G base station heat exchangers and sealed power cabinets.
Industrial HVAC & Commercial Ventilation: Air handling units (AHU), evaporative condensers, and process duct boosting.
