Case Studies

Holmfirth Dyers Limited






Established in 1985 as Commission Dyers and Finishers, Holmfirth Dyers work closely with Designers, Dying and Finishing fabric for the Fashion and Upholstery Industries. The business is family-run, processing in excess of 6.3 million metres of fabric per annum in a plant renowned for its investment in cutting-edge technology and service-driven delivery to their valued customers


The company was looking to reduce their energy costs and energy consumption at their works in Holmfirth, becoming more environmentally friendly in the process. Machinery which is key to the company’s operations, could not be affected by any potential energy-saving solutions to be installed on-site.


Powerstar completed a full site survey and found that there could be a significant reduction in energy savings, particularly on the Process Heating and Motors with variable speed drives. The full site survey also shown that replacing the existing, inefficient transformer, would provide further savings. A Powerstar HV-MAX 1000kVA system was installed replacing the existing transformer on site.


Equipment on site now has reduced maintenance costs and increased lifespans thanks to the new, corrected voltage level. The HMI (Human Machine Interface) allows for savings data to be monitored at the unit or via a desktop application.

The HV-MAX unit regulated voltage output with its super low-loss amorphous core reducing energy consumption on the site by 10.9%. A cost saving of £13,852 per annum and the equivalent of 88 tonnes of CO2 emissions.
