Driving down energy costs
20 April 2015
Accurate end-product sizing, lower maintenance costs, quieter operation and reduced energy bills are the results of replacing DC drives and motors with their AC equivalent across two extruder lines used in the production of the breakfast cereal, Weetos.
Following an an energy and productivity review, eight ABB industrial drives, five ABB general purpose drives and low voltage ABB motors, rated from 0.75kW to 250kW were installed. The equipment was selected as the incumbent drives supplier is not able to offer a drives and motors matched pair.
Following the installation a 20% drop in energy consumption was observed. The results showed that by changing to AC drives, Weetabix has saved some £28,000 per year, with a payback within three years.
