OverviewInstallation of an Atlas Copco GHS900 VSD+ vacuum pump.
What was neededThe job focused on three vacuum pumps, one of which required major repairs. The site had received environmental awards for its green credentials and it made sense to assess the operation of these existing air compressors to establish the potential energy savings that could be made by replacing them with a more energy efficient unit.
What we didPPS installed one of Atlas Copco’s latest GHS900 VSD+ vacuum pump at Polestar Sheffield on a trial basis to show how it could reduce the company’s energy bills. One of the new generation of intelligent, oil-sealed, plug-and-play rotary screw vacuum pumps from Atlas Copco, the GHS900 is designed to deliver peak performance at the required operating pressure.
Why PPS?PPS had previously installed pipework at Polestar Sheffield and the two companies had already established an excellent working relationship.
Key benefitsThe benefits of the GHS900 VSD+ include superior performance, increased efficiency, quiet operation, sustainable productivity and reduced environmental impact. Of the three existing units, the two smaller vacuum pumps previously used by Polestar were running at approximately 20KW an hour (one rated at 11KW and the other at 9.7KW combined). The Atlas Copco vacuum pump that replaced them was a 15KW unit, which runs at around 20% load, equating to 4KW. Based on an operation of 8,000 hours per annum, the estimated savings are expected to be just over £10,000 (16KW x £0.08 x 8,000 hours). Although this saving will depend on demand, early indications match this projection.
“At Polestar Sheffield we pride ourselves on using the latest technology and continually looking at ways to save energy, which is why it made absolute sense to listen to PPS when they suggested trialling a variable speed drive vacuum pump. “The Atlas Copco GSH900 VSD+ vacuum pump installed by PPS has proved a resounding success, and the projections are for major savings on our energy bills over the course of a year. We would definitely work with PPS again and recommend their services to others.”
