Frequency Inverters

The frequency inverters – or variable speed drives (VSD) – are used for regulating the speed of the chimney fans with three-phase motors.

All CFIR inline fans have special EC (electronically controlled) motors that can only be regulated by using a frequency inverter.

The inverters are used in combination with the controllers EBC22/24 or the manual controller Pot S.

All FRK frequency inverters are pre-programmed with a unique software tested and designed to suit each fan.
