When the temperature of the radiator exceeds the operating temperature or the air conditioner is turned on, the control module will start to control the cooling fan and adjust the fan speed at any time to maintain proper operating temperature of an engine. 

    In the safety part, once the current is too high or low or the fan is burnt due to block by foreign objects during operation, the function of the control module made by LUL can detect and protect the fan immediately. 

    In standby mode, it is also a low-power standby. Most of the market is the sub-factory control panel, which consumes power and causes the battery of the car to be too low to start.

    LUL products have been sold in America for many years, also have been tested and certified by the market and won the satisfaction and guarantee in quality from many customers.
