Abstract: A mobile cooled storage unit (10) has a sectional racking structure (17) for storing items such as bodies and body parts to be cooled. The racking structure is assembled at a location where the cooling unit is to operate. A removeable insulated outer cover (11) is placed over and supported by the racking structure to enclose the structure and any items stored thereon. A chiller (25) is connected with the interior of the cover for cooling the stored items. Several such units may be connected together to provide a larger overall unit which are cooled by one or more chillers. The invention also provides a method of establishing a temporary cooled storage unit.
