Energy-saving is the most important feature that will be taken into consideration because the evaporator fan motors run twenty four hours a day. The second magnetic filed in an AC motor is inefficient and creates “air losses” while that in a DC/EC motor can remove the losses. Thus the same power can be generated from a smaller DC/EC motor than its equivalent AC motor. EC motors decrease energy usage and increase net cooling capacity through the reduction of waste heat from the motors. Xhengxin supplies high efficiency EC fans for commercial refrigerators, freezers and for your solar refrigeration solutions.
