Correct answer
Insulated equipment.
Insulated equipment. Insulation limits heat transfer between the inside and outside; it does not itself produce cold. Refrigerated equipment adds a non-mechanical cold source, excluding compression or absorption equipment. Mechanically refrigerated equipment uses a refrigeration appliance. Insulation and cooling perform different functions.
