What Are the Different Types of Commercial Refrigeration Equipment?

There is a wide variety of commercial refrigeration systems:

  • Reach-in vertical cases and refrigerators
  • Plug-in enclosed vending machines
  • Semi-vertical display cabinets
  • Horizontal cases2
  • Deli cases

The various commercial refrigeration equipment can have different functions:2

Chillers

Freezers

Freezers keep perishable items frozen, preventing them from spoiling.2

Combo Chillers and Freezers

Combination commercial refrigeration units can allow for both chilling and freezing perishable items.2

In industrial settings, refrigeration units may be used during the production process of plastic or metal, as well as to help with the fermentation process of beverages.6

Industrial refrigeration may also be used to provide environmental testing of parts or components. The refrigeration system can create extremely cold environments to test whether or not parts will experience failures or shortened lifecycles under certain conditions.6
