Europe’s leading copper producer Aurubis is implementing a major upgrade at its copper plant in Bulgaria, with 460 older, inefficient motors replaced by IE4 & IE5 motors. Many of these will be paired with matching ABB drives. The upgrade will save so much energy that the project will pay for itself in only 3.5 years. Other benefits include reduced carbon emissions, increased process flexibility and improved performance.
