Air-tight energy saving slashes Marshalls carbon footprint 18 July 2012

Hard landscaping products supplier Marshalls is reporting significant energy and operating cost savings since implementing remedial action following air leakage audits at nine of its plants.

The company, which is a major user of compressed air. approached maintenance, repair and overhaul specialist Brammer to conduct full air leak audits at its manufacturing facilities.

Brammer's Nick Cork says that its audits involved using a range of tools to detect all air leaks, photographing leaking units and specifying appropriate parts for repair.

On completion of this stage of the process, Brammer's engineering team worked on the sites to address any issues likely to hamper remedial work, and initiated alternative plans to eradicate problems.

"Compressed air audit have the capability to provide immediate energy savings, which could be as high as 30%," says Cork.

"When the potential to reduce operating costs by 50% is also taken into consideration, the overall impact on the bottom line is sizable," he adds.

"Brammer and Marshalls have worked in partnership to conduct air leak audits on all major manufacturing sites within the group," confirms Peter Stevens, group carbon & energy manager at Marshalls.

"This enabled us to reduce our carbon footprint by 426 tonnes. Future work includes video tutorials for staff on better air management to achieve further savings," he states.

Following Brammer's audit at Marshalls and the completion of the remedial work, Brammer is now working with Marshalls to cut the pressure at the compressors and to install lineside monitoring equipment so that future leaks can be identified as soon as they occur, he adds.
