Animal feed manufacturer, ABN, is
saving over 30% of the power
consumed on the applicable motors
on its electricity bill for the
manufacture of pig and poultry feed
products following installation of 33
ABB low voltage AC drives.
The company wanted to look at
the energy efficiency of some of its
key processes, such as cooler fans,
grinders, grinder extractor fans and
air compressors, and asked ABB
Drives Alliance Partner, Inverter
Drive Systems (IDS) to investigate.

Machines had either no control or
a simple damper control on the fan
applications. IDS conducted an
energy survey at seven mills,
involving temporary installation of
low voltage AC drives to determine
potential savings. The survey
revealed potential savings of about
25% of the power on the
recommended applications.

A total of 33 ABB industrial drives
were installed at the mills, with
ratings ranging from 7.5 to 200kW.
