Closed-loop counterflow cooling tower components feature dual-speed motor: The dual-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 load, which can be achieved through the dual-speed motor, resulting in energy savings. Additionally, the fan can significantly reduce the noise of the unit when operating at low speed.

Variable Frequency Motor: Variable frequency motors are suitable for applications in condensers where variable frequency drive is used for capacity control. They enable energy to be infinitely adjusted.

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