Brammer helps to reduce Marshalls’ carbon footprint by 426 tonnes
UK hard landscaping product provider, Marshalls, approached Brammer, supplier of manufacturing, repair and overhaul products and services, to conduct a full air leak audit at its manufacturing facilities. Brammer has now completed nine surveys at Marshalls sites to date.
Brammer’s audit involved using specialist equipment to detect all air leaks, identifying each leak with a number, photographing the leaking units, and specifying the appropriate parts for repair in order to make it easier for the completion of remedial work. On completion of this stage of the process, Brammer’s engineering team worked on site to address any issues likely to hamper the remedial work and initiated alternative plans to eradicate such problems before the ‘fix’.
Sizeable bottom-line impact
Nigel Cork of Brammer believes a compressed air audit has the capability to provide immediate energy savings which could be as high as 30 per cent. When the potential to reduce operating costs by 50 per cent is also taken into consideration, the overall impact on the bottom line is sizable.
Cork said of a typical air leak audit: “It normally includes an examination of both air supply and use, and the interaction between supply and demand. The output of a compressed air system, energy consumption in kilowatt-hours, and the annual costs of operating the system are calculated. The auditor also measures total air losses from leaks and locates those that are significant. All components of the compressed air system are inspected individually and problem areas identified, a report is then prepared with a recommended course of action.”
Following Brammer’s audit at Marshalls and the completion of the remedial work, Brammer is now working closely with Marshalls to lower the pressure at the compressors and to install line-side monitoring equipment so that any future leakages can be identified as soon as they occur. This enables remedial work to be factored in to either a planned maintenance programme, or undertaken as part of an unscheduled outage.
Peter Stevens, group carbon & energy manager at Marshalls, said: “Brammer and Marshalls have worked in partnership to conduct air leak audits on all major manufacturing sites within the group. 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.”
