Refrigerated freight container

Abstract

A refrigerated freight container is provided comprising thermally insulated sidewalls [ 2], roof [ 3] and floor [ 4], a thermally insulated access opening at one end of the container and a refrigeration installation [ 10] at the other end of the container. The refrigeration installation is built into a removable end wall unit [ 8] that closes off the end of the container opposite the access opening in the installed position. The access opening preferably includes a surrounding frame [ 7] forming an access opening unit that is also removable from the container. The sidewalls of the container are preferably hinged [ 15] in a central region up the height thereof so that they can collapse inwardly in concertina fashion with the roof moving towards the floor of the container and the central regions of the sidewalls folding inwardly towards each other. A separate holder [ 20] may be provided for holding one or more removable end wall units and one or more removable access opening units [ 5] when the container is in the collapsed condition.
