Installation of a new Atlas Copco GA11VSD+FF variable speed drive compressor.

What was needed

Based in Milnsbridge, Huddersfield, Crossgrove Associates manufactures corrugated cardboard boxes and provides innovative packaging and design solutions for a diverse range of businesses UK wide. The company was running 22,000 sq ft of machinery from a larger than necessary Sullair MS3707 37kw screw compressor. When Dave Jones of PPS came to service the machine, he identified that there was potential for significant cost savings by moving to a new Atlas Copco variable speed drive compressor.

What we did

A datalogging survey and simulation carried out by PPS suggested that by switching to an Atlas Copco GA11VSD+FF variable speed drive compressor, Crossgrove could reduce its annual running costs from £6,450 to around £905 – a saving of £5,545 pa. Initially, Marc Auty, the Director of Crossgrove Associates, was sceptical about the potential savings, so Dave Jones offered the company a month’s free trial. This would allow Marc to compare the data logging from the old machine with data from the Atlas Copco compressor. A new GA11VSD+FF variable speed drive compressor was installed and the relogged running costs were even lower than predicted: £770 pm, representing an annual saving of £5,680 pa. At the same time, PPS put Marc in touch with Kirklees Council, which was offering eligible businesses up to £5,000 (up to a maximum of 50%) towards capital purchases that provided energy savings and reduced the company’s environmental impact. Their representative carried out an audit at Crossgrove’s site and confirmed that the company would qualify for the grant.

Why PPS?

Crossgrove Associates was already using PPS to service its compressor and it was simply a case of taking advantage of energy-saving – and cost-saving – recommendations that the company was able to offer.

Key benefits

Because the old compressor was so inefficient in its electricity usage, the new Atlas Copco variable speed drive compressor offered a significant reduction in running costs. With the additional benefit of the Kirklees Council grant, the final payback was reduced even further, to just seven months. Crossgrove was also impressed by the small footprint of the new compressor, which takes up much less space than the old one.
When the idea of a new machine came up, I thought it was a sales pitch – trying to talk me into something I didn’t really need. The key was when Dave Jones offered to put a machine in free of charge to prove the statistics. I thought, you’ve got to be pretty confident to do that. From a financial point of view, cash is tight in any business at the moment, but getting 50% of the costs paid by Kirklees Council was a big factor. It was a great idea for Dave to have the relevant contact details with him when he came. It was almost pre-packaged for me; it made my job as simple as possible. When you bear in mind that I was going to get half the new compressor paid for, plus we knew from the monitoring exercise that it was going to save us a fortune in electricity, it was a no brainer. A good summary of the experience? Significantly easier than anticipated. I’ve referred PPS on to a couple of other companies already.
