Highland Spring Case Study

Established in 1979, Highland Spring Group is the UK’s leading producer and supplier of natural source water.  Now bottling over 600 million litres of water a year across five sites, the Highland Spring Group produces brands including Highland Spring, Speyside Glenlivet, Hydr8 and a range of private label flavoured and unflavoured waters for some of the UK’s major supermarkets and foodservice retailers.

Key objectives

  • Line Continuity
  • Return on Investment


Highland Spring asked us to find them a solution to help solve an issue with excess moisture on the label area of the bottles. A 'water in glue contamination' was creating issues at the labeller on the newly installed high-speed bottling line, resulting in the majority of line downtime, costing the business not only in monetary terms but also in quality.  Air hoses were being used to try and overcome the issue, however, due to the speed of this line, they were unable to impact significantly enough to show a real difference.


After analysing and understanding the specific requirements to meet the project team's objectives, we established that a Sonic Air System would be the best product for the challenge. This system has a performance guarantee and is the most energy-efficient air knife. It was more than capable of coping with the line speed ensuring the label area on the bottle was dry, meaning no water in glue contamination in the labeller machine. This ensured continuity of the production rate, meaning less downtime and therefore delivering a positive return on the investment.


"The Sonic air system from CPA has exceeded expectations, we can see a reduction in line downtime by over a quarter in the year since installation. We trusted the team at CPA to deliver on our objectives and we are completely satisfied that we have the best product installed"
