Abstract
A removable modular duct system for conducting air in a temperature-controlled cargo container. Temperature-controlled air produced and propelled by a refrigeration unit, is conducted along the modular duct system by one or more duct sections and a transition section that conducts air from the refrigeration unit to the duct sections. The air may be discharged laterally via lateral discharge openings in the duct sections. An end section may be coupled to the duct sections to discharge air at the end of the duct system.
