There are also specifications with dimensions of 5.69 meters × 2.13 meters × 2.18 meters and a gross weight of 17.5 tons.
The internal dimensions of a 40-foot refrigerated container are usually 11.58 meters × 2.29 meters × 2.50 meters, the gross weight of the cargo is generally about 22 tons, and the volume is about 54 cubic meters. If it is a 40-foot high cabinet refrigerated container, its height will be higher than that of a standard 40-foot container, and the volume will increase accordingly.
