Some embodiments of a system for partitioning cargo spaces in a temperature-controlled cargo container can include one or more longitudinal panel assemblies with a user-selectable height feature. The design improves mixing and gas contact, yet has reduced power requirements, by using a plurality of debris-shedding, finned aspirator tubes to inject approximately 35% more air than the best prior art designs at the same rotational speed. As prior soil releasemoisture wicking treatments do not function properly, or, alternatively, compromise hand or other properties of certain target textiles after treatment application, a new, effective, soil releasemoisture wicking formulation for such purposes was needed. The sleeve is disposed about the first and second intermediate segments between the first and second ends of the loop portion.
