Shipping containers are commonly used for storing and transporting various types of goods. These containers are designed to withstand harsh weather conditions, including extreme temperatures and humidity levels. However, one of the most common problems associated with shipping containers is condensation. When the temperature inside the container drops below the dew point, moisture accumulates on the interior surfaces of the container. This can cause various issues such as corrosion, mould growth, and damage to the cargo. Proper airflow is necessary to control condensation in shipping containers.

Why Does Condensation Occur in Shipping Containers?

Condensation occurs when warm, moist air comes into contact with a cool surface. Shipping containers are made of steel, which is an excellent conductor of heat. During transportation, the container is exposed to different temperature ranges, causing the air inside to change and come into contact with the steel walls. If the temperature drops, the moisture in the air condenses and causes water droplets to form on the interior surfaces of the container.

How to Control Condensation in Shipping Containers

The best way to control condensation in shipping containers is to ensure proper ventilation and airflow. Ventilation allows moisture-laden air to escape while fresh air enters the container, reducing the relative humidity level. The most effective way to ensure proper airflow is to install vents at both ends of the container, both high and low. These openings allow air to circulate inside the container and prevent the build-up of moisture.

How are our vents different from our competitors?

Our MV303 vents have increased airflow of just over 10% over most of our competitors’ vents due to additional air holes and modified internal baffles. This allows for increased airflow, reducing the risk of condensation. Our vents are also designed to be slimmer than other v ents on the market, meaning they do not protrude from the container corrugations and are therefore less prone to scuffs and breakages. The third main benefit of our vents is the superior EPDM seal. The seal design allows for an improved seal between the vent and the container, eliminating the need for caulking around the outside, whilst maintaining the drain feature on the bottom of the vent to expel any residual water.
