Suzhou Dowell Ventilation Technology Co., Ltd is located at Suzhou city, China, one hours driving from Shanghai city. On based of our EC motors launching in 2017, we started to develop EC axial fans and EC centrifugal fans from 2022. Electronically Commutated (EC) means a fan which has a PMSM with onboard electronics to for controlling a fan. Common fans within the air conditioning and ventilation units are AC induction motors with one speed. It is necessary to add belts and pulleys or reducer to change the speed. At the same time, unnecessary air movement is also not required as per actual applications.
In view of these factors, EC technology is a great choice. EC motor direct driven coupling to fan impellers and infinite speeds regulating by input logic signals will offer high airflow efficiency, low power energy and noise level. It is a intelligent control system. in order to provide qualified products to our customers, we have our motors design team, test laboratory and EC motor assembling line in Suzhou city. And the EC fans division consist of impellers design, EC fans performance test and well balanced. Not only in providing our standard EC motors and EC fans, we are more interested in OEM the suitable products for our customers as per their technical request.
