Refrigeration costs cut

The company wanted to replace its old refrigeration facility with modern equipment and get better control of the refrigeration plant and reduce the potential impact of harmonics.

Paul Derbyshire, electrical, control and automation engineer for McCain Central Engineering GB, says: "We were looking for the best drive for this application and investigated several solutions from a number of manufacturers.

"We found that nothing gave the same performance as ABB active front-end variable-speed drives. With ABB drives, there is no interference on the line and they do not need filters to cut harmonics, as other drives do."
