Calibrate is making net zero a reality for high energy-use businesses.

 Calibrate Energy Engineering, part of RSK Group, has scooped the award for Non-domestic Ground Source Heat Pump in the industry renowned ACR & Heat Pump Awards for the fourth time.  This makes them winners five times over as they were awarded Installer of the Year in a previous year.  The company also received a highly commend in the Non-Domestic Heat Pump category.

Calibrate design, install and maintain commercial scale renewable technologies.  The project that scooped the win was a highly efficient 2-phase 3MW Ground Source Heat Pump system for a client in Scotland, with big plans for expansion and growth.   Due to the nature of their fruit processing business, they require large amounts of heat and chill to ensure that their product is processed and stored in premium condition.

The pioneering systems that Calibrate designed and installed, the first in 2021 and the expansion in 2023, ensured minimal business disruption, as the heat pumps’ plantroom was built offsite enabling a swift and trouble-free connection once the ground pipework was completed.  A key requirement was responsive and intelligent controls to ensure that the system was adaptive to the daily needs of the business, whose success lies on exacting temperatures and conditions.

The controls, branded Calibrate Analytics, are key to identifying efficiencies and can be attached to any heating or chilling asset to identify how savings can be made.  This system now achieves 0°C at 300% chilling efficiency and 35°C at 450% heating efficiency, massively reducing energy use to improve bottom line performance.

Commenting on the win, Jack Smales, managing director of Calibrate said: “To win again at these prestigious awards in a category that is very much the pinnacle of our business has been another rewarding experience.  These awards showcase the best of the industry and demonstrate the highest level of knowledge and expertise, so it is great to win against other ground-breaking suppliers and projects.

“Aside of our accolade, what is more important is the costs and carbon savings that this and many of our clients are now saving as a result of these alternative technologies.  A change in mindset on how we heat and chill our processes and spaces results is an outcome that is far kinder to the planet and purse.”

Presenting the Award on the night was Axel Blake, 2022 winner of Britain’s Got Talent, who also provided the entertainment on the night. Accepting the award on behalf of Calibrate was Emma Tandy, marketing manager who said: “Every year we go along thinking, we won’t win again, and we are always surprised and thrilled to come away with a trophy.  As always, we were up against some strong competition in the industry, so it was very humbling to be acknowledged again.

“As a pioneering business in the industry, visibility like this helps us to get closer to our vision of making net zero a reality for businesses through innovative technologies.”

Calibrate continue to focus on helping high energy-use businesses, and to date Calibrate have installed 300MW of heat pumps and renewables to high energy-use businesses, whilst preventing the release of tens of thousands of tonnes (and counting) of carbon into the atmosphere.
