Leister frequency converter complements its air blower range
Leister now offers a matching frequency converter as an accessory for its ROBUST, SILENCE and ASO blowers. Using the frequency converter you can steplessly adjust the air volume - with a push of the button or remote controlled by a PLC (Programmable Logic Controller). The blower performance can be increased by up to 60%. The results are more efficient processes and therefore lower costs.
Frequency converter's mode of operation
The frequency converter is an electrical unit which is connected to a single-phase main voltage on the input side and generates a three-phase signal with variable frequency on the output side. The rotational speed of a blower is normally constant. It can be steplessly adjusted with a frequency converter.
High Blower performance
When using a frequency converter, the blower can turn with a higher frequency than that of the power grid. Therefore up to 60% more performance is generated. In certain cases, this can mean that the process is realisable with only one instead of two blowers. Too low or too high a rotation speed can lead to thermal or mechanical damage on the blower. The Leister FC550 frquency converter is configured so this does not occur.
