Abstract
A high performance freezer includes a deck and a cabinet supported above the deck and having a cabinet housing defining a generally cylindrical shape. The freezer includes a door supported by the cabinet housing that moves between open and closed positions by sliding or pivoting generally along the side wall of the cabinet. The freezer further includes a refrigeration system mounted at least partially within the deck and partially within the cabinet to refrigerate an inner chamber of the freezer. The cylindrical shape of the cabinet enables rotation of shelves within the inner chamber and a maximized storage space with a minimal floor space required.
