Container rain

During the days and nights of a cargo's journey, the temperature inside a container will rise and fall, causing humidity level to fluctuate and result in two basic processes of water condensation.

Container rain -- Whenever goods are moved from a hot climate to a cooler climate, the air will reach the dew point and vapor will condense into water. Condensation can form on the ceiling and walls of the container. This moisture can drip on to the cargo.

Cargo sweat -- Moisture evaporating from cargo due to high temperatures in containers which can reach over 60 ℃.
