Engineering Steel Belgium (ESB) is
reported to be saving 45,000 Euros
per annum on the operation of three
cooling pumps on one of its electrical
steel furnaces, since the installation of
three WEG W22 132 kW, IE2 high
efficiency motors, controlled by WEG
CFW-09 variable speed drives. The
WEG equipment was supplied by
WEG distributor, Leclercq Energy, to
Processautomation, who supplied and
commissioned the complete energy
saving package.

The WEG CFW-09 132kW inverter
drives selected for the motor control
task are matched to the W22 motors,
producing the optimum operating
characteristics for high efficiency
operation. A key feature is the
CFW09’s self-tuning feature, which
automatically matches the drive to the
motor and load, relieving the user of
the task of entering a motor map.
