Commercial refrigerators and freezers are available with the compressor mounted to the bottom of the unit or the top of the unit.
Bottom-mounted refrigeration units generally have the added bonus of a “no-stoop, lower shelf,” with the added convenience of additional storage room at the top of the unit. Since the compressor is located at the bottom of the unit, it will perform in the coolest, most grease-free area of your kitchen. Servicing a bottom-mounted refrigeration unit is generally easier due to its convenient location.
Top-mounted refrigeration units generally feature an optimum amount of storage, in terms of cubic feet. Many restaurant owners feel that a kitchen with a top-mount refrigerator or freezer will stay cooler, since the warm air produced by the condenser is stays high above the working area.
