There are three climate classes for commercial refrigeration. Most UK kitchens need just one, but plenty of operators have the wrong one fitted.
The result: energy consumption above the rated figure, a compressor running harder than it should, and a warranty that does not cover the conditions the unit is actually running in.
We have broken down the numeric class system (Class 3, 4, and 5): what each class means, how to measure your kitchen correctly, and how to spec the right unit.
