How to prevent water in shipping containers? The water in the container can be divided into the following situations: the cargo itself, the box condensation, the sea water immersion, the fresh water immersion.

Moisture or moisture is carried into the container along with the cargo. For example, if a container contains five tons of furniture, the furniture itself will contain about 8 to 25 percent humidity, depending on the type of wood and the degree of drying of the furniture. This corresponds to about 400-1250 litres of water. Some of the moisture here will be emitted into the air inside the container, becoming an important source of condensation of water vapor in the container.

When the temperature drops from 30 degrees Celsius to 18 degrees Celsius, water vapor condenses into water droplets. In a 40-foot container, 1.000 grams of condensed water is produced, causing "container rain."
