Walk-in chiller and freezer rooms, built and refrigerated to suit your premises, then kept running with planned maintenance and breakdown cover.
Built to size
We specify the room, refrigeration plant, evaporators and controls for your throughput and temperature requirements, whether that is a small bar cold room or a larger food production space.
Alarms and monitoring
Temperature alarms and monitoring give early warning of faults, protecting stock and helping with food safety records.
Servicing and repair
We maintain and repair existing cold rooms, including those we did not install. See commercial refrigeration.
