Reversed-flow closed-loop cooling tower components feature a two-speed motor: The two-speed motor offers capacity control. When the load decreases or the local wet-bulb temperature changes, the fan does not need to operate at full capacity. This can be achieved through the two-speed motor, leading to energy savings. Additionally, operating the fan at low speed can significantly reduce the noise of the unit.

Variable Frequency Motor: Variable frequency motors are suitable for condensers where variable frequency drive is used for capacity control. These motors enable continuous energy adjustment.

Electronic Water Level Controller: Cooling towers can be equipped with an electronic water level controller to replace the standard mechanical float ball water补给 device. Its feature is the ability to control water levels without on-site adjustments.
