Cooling tower fan EC motor
Animal husbandry fans should adjust the ventilation volume according to the ambient temperature during use, so as to maintain a constant temperature in the breeding area. The traditional damper control and variable frequency motor control have certain defects in mechanical structure, failure rate an

Product Details
Since the equipment capacity of the cooling tower in the central air-conditioning system is selected according to the maximum heat load in summer, in the actual operation of the equipment, due to environmental climatic factors, changes in the equivalent heat load and many other factors, the unit equipment is often at a low level. Running under load conditions, causing unnecessary power loss. Therefore, the PWM speed regulation EC motor fan is used to adjust the speed of the cooling fan and the number of cooling fans turned on through the intelligent control logic system at night or in a climate environment with low temperature, so as to achieve the purpose of energy saving and high efficiency.
Fan-specific ECI motor features:
● Specially designed for fans, more suitable for low speed and high torque operation of fans
● Permanent magnet synchronous motor with built-in driver
● Efficiency: Low power loss: The control of variable speed will change the air volume of the fan, and the reduction of the speed will greatly reduce the power
● Noise reduction:
● Intelligent control: 0-10VDC speed adjustment; forward and reverse rotation adjustment; start-stop control; ModBus RS485; speed feedback; 12VDC power output
