Especially in the field of wastewater technology, it is a considerable advantage to be able to react variably to changing requirements. A classic example is night-time shutdown to save energy during low-load hours. This demonstrates the superiority of a control unit with speed control:
The frequency inverter reduces the energy consumption of the system without having to close the pipe. This advantage offers considerable savings potential.
Energy saving through speed control: Half speed = one eighth of full load power
