|---|---|
Suzhou Dowell Ventilation Technology Co., Ltd., a leading EC fan manufacturer based in Suzhou, China, specializes in providing energy-efficient ventilation solutions for industrial applications. With years of expertise in designing and producing high-performance EC motors and EC fans, we offer the Energy-saving EC Axial Fan, specifically engineered for cooling tower applications. Our advanced EC fan technology ensures optimal performance, superior airflow, and enhanced energy efficiency, making it the ideal solution for modern industrial cooling systems.
Our Energy-saving EC Axial Fan is equipped with a highly advanced wiring system, consisting of 12 color-coded wires, divided into control lines and power lines. The control system offers features such as speed output, switch control, 12V power supply, variable speed control (VSP), and a MODBUS RTU communication interface for seamless integration. The fan operates on a three-phase power supply, equipped with professional PE protection grounding, ensuring both stability and safety during operation.
Powered by a permanent magnet brushless EC motor, the fan is designed to deliver exceptional energy savings and variable speed control. The EC motor directly drives the fan blades, ensuring high airflow with moderate pressure, perfect for expelling moisture from cooling tower fill. The EC motor provides excellent adaptability to fluctuating thermal loads and changes in ambient temperature, offering significant energy-saving benefits.
The Energy-saving EC Axial Fan features a robust design with an IP65 protection rating, ensuring that moisture does not enter the motor, thus prolonging its operational life. Whether you require aluminum or PP blades, the fan blades are engineered to withstand the demands of high-performance industrial cooling systems, providing reliable and durable operation for years to come.
The fan’s wiring system separates power and control lines, making on-site connections easier and more efficient. The fan supports continuous speed adjustment through a 0-10VDC/PWM interface or MODBUS RTU, offering flexibility and precise speed control. As a supplier of EC fans, Suzhou Dowell provides RS485 communication protocols at no additional cost. Additionally, the fan can be installed either horizontally or vertically, depending on your specific project requirements.
