Soft drink manufacturer lowers energy costs by 45%
arrow_backTo the overview22 September 2022 | Grundfos
An onsite Energy Audit led to a solution that boosted system performance by 70% for the leading UK soft drink manufacturer Britvic and lowered the energy costs by 45%. Britvic will save an estimated EUR 69,500 annually and achieve ROI in less than two years.
Grundfos energy optimisation experts carried out an Energy Audit at the Britvic facility to identify opportunities for improving energy efficiency. Grundfos then designed and built a containerised solution that includes a booster system with 5 Grundfos CR XL 22kW multistage pumps in addition to a dosing and disinfection system for the water holding tanks and full, SCADA-compatible PLC control with remote access features.
The CR XL pumps deliver a flow rate of 290m3/h at a reduced pressure of 2.5bar. The built-in frequency drives continuously control pump speed, running each pump as efficiently as possible. The fully automated system ensures that the current production demand is met at all times with the lowest possible energy expenditure.
The solution was tested at the Grundfos factory before being mounted in a container and shipped to Rugby in Sunderland where it was craned into place in a matter of hours. Britvic worked closely with Grundfos to mitigate risk and facilitate a precise swap-over.
The outcome
With the customised Grundfos solution, Britvic has met all of its targets: Water flow has increased by 70% while reducing energy costs by 45%. The energy savings amount to EUR 69,500 annually; as a result, Britvic will achieve ROI in less than two years. The close partnership between Britvic and Grundfos ensured that no production time was lost during the project.
The efficient pumping system is helping Britvic meet its energy targets and is ready for future growth as it can deliver flows of more than 400m3/h. Britvic is considering replicating the solution at other sites in the UK and Ireland.
“The Grundfos booster pump system provided to Britvic has proved to be a great success even in the short time it’s been in operation,” says engineer Calvin Winch of Britvic. “Not only have we seen an immediately improved water supply with stable and constant pressure; we have been able to monitor and trend the flows, enabling continuous improvements on our processes. Working with the Grundfos team went as well as we could wish, and to lose no production time is a credit to everyone involved. Well done!”
