40 ft Refrigerated Container Dimensions

A 40 ft refrigerated (reefer) container is an insulated shipping unit with an integrated refrigeration system that maintains a stable set temperature during transport and storage. Compared to standard dry containers, internal volume is reduced due to insulation and the cooling machinery. Reefers typically run on external power (vessel, terminal, or depot supply) and can also operate via a generator set for road transport. Correct loading with clear airflow paths helps keep temperature uniform throughout the cargo space.

Use case: best for high-volume temperature-controlled cargo—chilled and frozen food, meat and seafood, dairy, fruit and vegetables, pharmaceuticals, and other products that must stay within a defined temperature range end-to-end.
