Abstract
A cooling and heating plate, in particular for serving food and beverages, is connected to a cooling unit and an electrical heating device, preferably a silicone panel heater, is also provided on the under side of the plate. The plate is a multilayered plate having an upper plate, preferably of chrome nickel steel, and an aluminum plate situated thereunder. At least one steel pipe, which is preferably seamless with serpentine curves, having a compressive strength of at least 50 bar is integrally cast in the aluminum plate. As a result, carbon dioxide can also be used as a coolant. Fastening elements can also be integrally cast in the aluminum plate.
Claims7
