Why Condensation Forms in the Container
During transport and storage, considerable temperature variations occur inside freight containers. Temperature differences of several tens of degrees Celsius can occur between day and night, not only at ports and stations located in different climatic zones but also during storage in the container at a fixed location. As warm or warm air can absorb much more moisture than cold air, temperature drops in airtight cargo containers lead to the formation of condensation and, thus, phenomena such as container sweat, container rain and cargo sweat. What is container rain? Container rain is condensed water that forms on the interior surfaces of the container. Due to the surface tension, the water that accumulates there concentrates into increasingly larger drops, drip off due to their weight. The resulting rain of containers then falls directly on the cargo. What is container sweat? Container sweat caused by falling outside temperatures usually occurs below the conta...
