A refrigerated shelf for a food display counter comprising a sheet of metal having an upper surface for supporting chilled food items and a cooling coil at the underside of the shelf, the coil being adapted for the flow of coolant therethrough for cooling the shelf. Heat transfer means in heat-exchange relation with the coil and the underside of the shelf is provided for effecting a substantially uniform temperature condition throughout the upper surface of the shelf.

A refrigerated shelf for a food display counter comprising: an upper member having an upper surface for supporting chilled food items and flanges extending down from the upper surface constituting side walls of the shelf; a cooling coil at the underside of the upper member, the coil being adapted for the flow of coolant therethrough for cooling the shelf; heat transfer means in heat-exchange relation with the coil and the underside of the upper member for effecting a substantially uniform temperature condition throughout the upper surface of the shelf, and with the coil and the side walls of the shelf for cooling the side walls; insulation covering the heat transfer means and the coil; a lower member secured to the side walls of the shelf covering the insulation, the lower member being contained within the upper member so that the lower member is at least at the level of the lower edges of the side walls, and having a perimeter spaced inwardly from the side walls; and a thermal break extending along the perimeter of the lower member in the space between the lower member and the side walls of the shelf to enable the lower member to be maintained at a temperature above that of the upper surface and side walls of the shelf.
