Cold room
Short definitionAn enclosed space built from insulated panels, with its own refrigeration system, that keeps product at a set temperature.
Three things define a cold room: the temperature to be held inside, the room dimensions and the product going in. Panel thickness, door type and the size of the refrigeration unit all follow from these three.
Chill rooms for fresh product run between 0 °C and +8 °C. Frozen storage rooms run between −18 °C and −25 °C. As the temperature drops, panels get thicker, floor insulation becomes mandatory and the air coming in through the door matters more.
