Abstract
A cover for a cooling unit, such as an evaporator assembly, of a display refrigerator. The cover is advantageously made of a single piece of material, preferably an injection molded, filled polypropylene plastic, which is capable of withstanding the harsh conditions found in a display refrigerator. The cover is further advantageously configured to enhance the operation of the evaporator assembly, protect the evaporator assembly, insulate the frozen or refrigerated food and drink items from the heat generated by the evaporator assembly, and decrease the time needed to install the cover into or remove the cover from the display refrigerator.
