Novelis, a world leader in aluminium rolling and recycling, is making huge savings in energy costs and significantly reduced its carbon footprint since Deritend re-engineered the fans on one of its curing furnaces.

With the Carbon Reduction Commitment looming this project will reduce the Novelis plant’s carbon footprint by nearly 700 tonnes of CO2 per year and save the company over £75,000 in energy costs at its plant in Bridgnorth, Shropshire. This is achieved by installing high-efficiency WEG motors and variable speed drives.

“Deritend provided a complete solution, fully costed and optimised for the best energy savings,” explains Paul Shrimpton, Electrical Engineer at the Novelis site.  “With a payback time of less than seven months, it was an easy decision for us to make.”

The Deritend team provided a trial system on a sale-or-return basis to confirm their calculations.  According to Mark Jackson of Deritend, from the outset, knew the potential savings of their solution: “We knew that the savings were there, so it made sense for us to show the customer exactly what the improvements would be. We work closely with the customer to understand their process and deliver the system that best suits them.”

Novelis made its own measurements to confirm those made by Deritend and were delighted with the results.  Shrimpton confirms: “We actually saw a slightly better energy saving than we anticipated and were more than happy to go ahead with the full project as a result.  Deritend has over-delivered and you can’t ask for more than that.”
