ABSTRACT:
An apparatus and system is disclosed for fabricating refrigeration cabinets of the type including an outer shell and inner shell separated by an insulating medium, such as polyurethane foam. The inner and outer shells are each formed of a plurality of plates which, according to the invention, are maintained in their respective relative positions long enough to permit the insulating medium forming components to be introduced therebetween and to cure and adhere to the plates so as to thereafter maintain the plurality of plates in their predetermined relative positions as an integral cabinet without the need for prior securement. A novel thermal insulating member is also disclosed which extends along the forward marginal portions of the inner shell to prevent heat transfer between the inside of the refrigeration cabinet and the outside atmosphere during operation, while simultaneously maintaining electrical wires connected to the electrical system of the cabinet, or tubing for fluids or gases depending upon the installation in secured and hidden locations. Novel methods and systems are also disclosed for fabricating general purpose cabinets as well as refrigeration cabinets.
