Fact Sheet

VLT® Refrigeration Drive FC 103

Regardless if you want to operate
compressors, pumps or fans, the
VLT® Refrigeration Drive FC 103
provides you the possibility to save
energy and extend the lifetime of
the components.

Speed control provides many benefits
in all motor driven parts of refrigera­tion applications. The VLT® Refrige ration
Drive moves the user in the position to
profit from this in a very simple way.

One drive for all

The VLT® Refrigeration Drive FC 103
covers a power range between 1.1­315 kW. Available in a variety of protec­tion classes the drive suits the needs
of pump, fan and compressor applica-

Dedicated to
refrigeration
application

Designed to suit
fans, pumps and
compressors in any
kind of refrigeration
application.

tions. Every application and power size
can be operated and programmed with
the same common user interface.

The wizard menu also supports the
commissioning engineers if they
encounter any problems. The menu
will help the engineer troubleshoot
and offer solutions to get the drive
