Abstract: An enclosed container for storing temperature sensitive goods. The container has opposed side walls and end walls as well as a floor and a ceiling. First and second bulkheads are moveably mounted within the container for dividing the container into three separate compartments. Two end compartments are services by fixed heat exchanges for conditioning the air in the compartments. A center compartment is serviced by a movable heat exchanger. By repositioning the bulkheads and the movable heat exchanger the volume and thus the load carrying capacity of the compartments can be varied to accommodate different types of cargo and the temperature levels in the compartment independently maintained.
