Variable-Speed Drives Reduce Energy Costs for UK Pastry Producer

Tamar Foods, one of the U.K.’s largest producers of pastry-based products saved 23% on its HVAC energy costs following the installation of ABB variable-speed drives in its Callington plant in Cornwall.

Inverter Drive Systems (IDS), an ABB Drives Alliance member, looked at the potential for savings on the plant’s HVAC system. This accounted for approximately 15% of the total electrical use of the company. In order to change those readings, IDS did a retrofit of the HVAC system with 11 ABB standard drives for HVAC with ratings ranging from 15 to 45 kW.

Before the installation of the drives the company was using approximately 2,600 kWhrs a day for the HVAC system. After the installation, this fell to 2,000 kWhrs a day, a saving of around 23 per cent.

IDS installed a 45 kW ABB drive on the chilled water pump. This has resulted in a 43% savings on the pump’s electricity cost, with a payback time of less than a year.
