The system provides the ability to split a container into two variable-sized compartments with different temperature requirements. It can alternately cool one compartment and freeze the other or, if required, refrigerate one compartment and heat the other. The container can also be operated as a single compartment, as needed.
The ThinLine DT host unit is nearly identical to Carrier’s ThinLine NT unit. Its evaporator can freeze, refrigerate or heat/defrost the front compartment, while refrigerating and heating/defrosting of the rear compartment is done by an aft evaporator that is mounted from the ceiling and protected by a steel cage.
An insulated moveable bulkhead partitions the container into two sections. This slides along a track and adjusts 6 ft from centre in either direction, allowing the container to be divided into two 20 ft compartments or two compartments of variable size up to a 14 ft/26 ft combination. The front compartment delivers the standard frozen/perishable range of -30ºC to 30ºC, and -30ºC to -1ºC when dual-temp mode is activated. The rear compartment offers a perishable-only range of -2ºC to 21ºC.
The benefits, says Carrier, are better container utilisation and lower shipping costs. Instead of shipping two partial loads requiring different temperatures in separate containers, they can be shipped within a single 40 ft high-cube unit. “It is perhaps the most versatile container refrigeration system developed by Carrier. It addresses the fact that one size does not fit all needs,” said Scott Pallota, Carrier Transicold’s director of marketing.
