Device for supplying a circuit of a heating or cooling supply system

A device for supplying a circuit of a heating or cooling supply system, comprising:

• a structural component group made up of units for conveying a medium and for regulating and monitoring the medium, including fittings and connecting parts, that are combined in parallel pipelines for forward and return flow;
• a housing in which the structural component group is arranged so as to be ready for installation, the housing being made of a thermal insulating plastic material and divided into a lower shell and an upper shell by a seam that extends approximately in a central plane formed by the parallel pipelines;
• lock-seam connection means for connecting together the lower shell and the upper shell, the connection means including lock-seams that form a positive-locking connection along an outer edge of the upper and lower shells, the upper shell being provided with openings so as to permit selected components of the units to pass through the upper shell;
• and means for directly fastening the lower shell to a wall, the material of the lower shell and upper shell having a strength and thickness so that the housing is usable as a protective transportation package for the structural component group and as thermal insulating sheathing after installation.
