Abstract

A refrigeration machine for merchandising and displaying frozen articles. The refrigeration machine has a cabinet having a front wall, opposing side walls and an intermediate support shelf. A top portion of the front wall and the side walls extend above the intermediate support shelf to define a refrigeration unit compartment. The top portion of the front wall has a thicken area and a forward portion of the side walls also have thickened areas that are continuous with the thickened area of the front wall. The thickened areas form a boss which engages a divider wall of a refrigeration unit. The refrigeration unit is removable from the cabinet as a single member. The refrigeration unit has mounts for a compressor and a condenser so that an electrical tray and a condensate tray can be placed under the compressor and condenser. The cabinet has shelf supports that support shelves at varying degrees of inclination. For this, the shelf support have support surfaces and abutment surfaces and the shelves have supported surfaces and stop surfaces.
