6.3 Advantages

6.3.1 Why use a Frequency Converter for
Controlling Fans and Pumps?
A frequency converter takes advantage of the fact that
centrifugal fans and pumps follow the laws of propor-
tionality for such fans and pumps. For further information
see the text and figure The Laws of Proportionality.

6.3.2 The Clear Advantage - Energy Savings
The very clear advantage of using a frequency converter
for controlling the speed of fans or pumps lies in the
electricity savings.
When comparing with alternative control systems and
technologies, a frequency converter is the optimum energy
control system for controlling fan and pump systems.
