A Company Well Connected
Our Mechanical division have successfully completed a mission-critical air conditioning replacement for the Loch Lomond Group distillery. The project involved replacing an obsolete, energy-inefficient system that had suffered catastrophic compressor and PCB failure, leaving the distillery’s main control room vulnerable. Because this room houses critical monitoring equipment that requires a strictly maintained temperature to function, a rapid and technically rigorous solution was essential to prevent operational downtime.
Our team supplied and installed a modern, high-efficiency R32 system, significantly improving the site’s carbon footprint and energy performance. To ensure long-term reliability, the project included a full pipework flush to remove old contaminants, followed by rigorous pressure testing and deep evacuation to eliminate moisture.


Loch Lomond Group is a world-renowned name in Scotch Whisky, but behind their historic craft lies a high-tech operation that requires precision environmental control.
The air conditioning system serving the main distillery control room had suffered a catastrophic failure. The outdoor unit had experienced both a compressor and PCB (Printed Circuit Board) failure. Upon inspection by our Mechanical team, it was confirmed that the manufacturer had designated the replacement parts as obsolete.
In a distillery environment, the control room is the “brain” of the operation. It houses critical monitoring and electrical equipment that must be kept at a stable, set temperature to prevent overheating and potential operational downtime. With the old system non-functional, a rapid, reliable, and energy-efficient solution was required.
Our Air Conditioning team designed a full replacement strategy to move the distillery away from their failing, energy-inefficient setup to a modern, sustainable system.
The old, obsolete outdoor and indoor units were removed. Before the new system could be installed, our engineers performed a comprehensive pipework flush. This is a vital step to ensure that any contaminants or old oils from the failed compressor are removed, protecting the new equipment from day one.
We supplied and fitted a new high-efficiency R32 system. R32 is the industry-leading refrigerant that offers a lower Global Warming Potential (GWP) and much higher energy efficiency than previous generations.
To ensure the integrity of the new installation, the system underwent:
The project concluded with a full commissioning process. This involved testing the system under various load conditions to ensure it maintained the exact set temperature required by the distillery’s critical control room equipment.


By replacing a “severely un-energy efficient” failed unit with a modern R32 system, we have provided Loch Lomond Group with three major benefits:
“In a distillery environment, temperature control isn’t just about comfort, it’s about protecting the technology that keeps the site running. We were able to take an obsolete, failed system and replace it with a high-efficiency solution that will serve the Loch Lomond Group for years to come.”
