Features of commercial freezers

Here’s what you need to be looking out for before you purchase a commercial freezer:

  • Capacity – The freezer needs to have enough space to store enough ingredients for your busiest service. If you get one that’s too small, food could be wasted, but if you get one that’s too big, it will take up too much space in your kitchen.
  • Size – The commercial freezer needs to fit in your kitchen. Remember to check your access to ensure it will actually fit through your door!
  • Climate class – This is the highest ambient temperature the freezer will operate at. Climate Class 4 is considered medium-duty, whereas Climate Class 5 is heavier-duty. If your kitchen is usually over 32°C you will probably want to go for a Climate Class 5.
  • Efficiency – The more efficient a freezer is, the less it will cost to run. Check the energy efficiency rating to help you make a decision.
  • Automatic Defrost – Some commercial freezers will feature an automatic defrost system to improve the performance of the freezer. If not, you will have to manually defrost the unit when it accumulates ice.
  • Doors – Some models of commercial freezer will come with self closing doors, which can be useful to save energy or if you’ve got your hands full. Some may also feature pedal opening, so you don’t need to touch the door making it much more hygienic.
