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 proportionality
for such fans and pumps. For further information see the text The Laws of Proportionality.
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 to be obtained.
When comparing with alternative control systems and technologies, a frequency converter is the optimum energy
control system for controlling fan and pump systems.
Example of energy savings
As can be seen from the figure (the laws of proportionality), the flow is controlled by changing the rpm. By reducing
the speed only 20% from the rated speed, the flow is also reduced by 20%. This is because the flow is directly
proportional to the rpm. The consumption of electricity, however, is reduced by 50%.
If the system in question only needs to be able to supply a flow that corresponds to 100% a few days in a year,
while the average is below 80% of the rated flow for the remainder of the year, the amount of energy saved is even
more than 50%.
