The fan speed controller YMC706 is designed to control to the speed of fan motor used in the outdoor air-cooled condensing unit, the motor speed of the pump of the water cooled condensing unit and the fan speed of the air cooler in the cold room so as to improve the efficiency of the system.
The fan speed controller collects the signal of the condensing temperature of the system and adjusts automatically the motor speed according to the set program so as to reduce the power consumption and stabilize the system pressure, especially during the winter when the ambient temperature is extremely low, it can raise the condensing temperature, increase the seasonal efficiency and protect the compressor.For example, when the ambient temperature is high, the fan speed controller can speed up the fan to reduce the raised condensing temperature (pressure) of the air cooled condenser, when the condensing temperature (pressure) is reduced, the fan speed can be adjusted to a low speed in order to maintain a desired condensing temperature (pressure). In real applications, the fan speed controller can make the system operate at the relatively stabilized condensing temperature (pressure) as the designed parameters.This type of fan speed controller is a linear speed control device, which consists of circuit board, execution module and sensor. The speed controller has different power ratings ranging from 9A, 20A, 30A up to 40A. We can also offer the fan speed controller for fan motors with larger power at your request.
