HVAC

EC fans are widely applied in HVAC systems, especially where speed control function is required and noise reduction matters. Xhengxin EC fans are intelligent speed regulated. The speed control function is achieved by an integrated PCB board. The direct drive by the inside magnetic field makes the motor run smoothly and noise lower. Xhengxin EC fans have been used as exhaust and supply air fans in a lot ventilation equipments by customers.

Cooling

EC fans are essentially fans with brushless DC motor, combining the advantages of AC and DC power. With the power transformation and controls achieved by built-in PCB board, the fans retain the high efficiency of a DC brushless fan without need of an AC to DC supply. Unlike traditional AC fans, EC fans have a wide operating range, the output and energy usage will remain relatively linear when speed is slightly increased or decreased. Thus, EC fans are the most energy efficient fans on the market and the ideal solution for cooling electronic devices, like data centers, vehicles, and any components that dissipate a lot of heat.

Air Purification

Apart from smart control and energy-saving, the compact size is one of the significant features of EC fans. The space-saving design of EC fans allows them to operate at a high capacity in a smaller physical size, which is larger due to the external rotor. And the less bulky design delivers better airflow. If fan filter units care the health of people in public areas, air purifiers care more the health of you and your families. The COVID-19 pandemic makes people pay much more attention to their indoor air quality and many air sterilizing purifier products come into being. The fans used in residential air purifiers are commonly small size and quiet-running. Xhengxin EC fans have been put into the R&D and mass production of air purifiers by many customers.

Refrigeration

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.

Automotive equipment

The EC brushless motorized fans can be used both in combustion engine thermal circuits and in electric vehicles. The built-in inverter allows for continuous speed control. The advanced technology ECM provide advantages in terms of efficiency, electromagnetic compatibility, temperature resistance and etc. Besides, EC motors are protective. If the fan is blocked or the permissible voltage/temperature range is exceeded, or in case of overcurrent or internal faults, the motor is shut off. Xhengxin EC motors provide locked rotor, reverse polarity, over voltage/temperature protections.

Medical Equipment

EC fans, with high performance, efficient energy consumption, low noise level,etc., are also favored in medical industry. The manufacturers of medical ventilation equipments, such as FFUs, AHUs, air showers and clean fan coil units all retrofit their products with EC fans considering their great advantages over traditional AC fans. Apart from these medical equipments, biosafety cabinets(also called biological safety cabinets), which are enclosed ventilated laboratory workspace designed to protect the user and surrounding environment, join in the trend of applying EC fans. Xhengxin EC fans have also been adopted by customers in this field.
