How to Lower Storage Container Condensation

 

When you store items in a standard shipping container outside, they are more susceptible to condensation. This can lead to condensation building up on the ceiling. Moisture damage in storage containers can be caused by the simple fact that warm, humid air can hold more moisture than cold air. It's like dewy grass on a summer morning. The temperature of a shipping container, a metal box, can quickly affect its condition. Humidity can develop inside a shipping container when it gets warm. Moisture can get into the container via evaporation or external sources. As the container cools, water droplets can form. Usually, these droplets form on the ceiling. Once the droplets get large enough, they will drip onto your stored items. If you don't address this, you could get a micro rainfall cycle which can cause water damage to your stored items.

 

Suppliers of container desiccant are not airtight. However, they will "breathe", due to temperature cycles. When the pressure inside the container drops, it cools. The pressure is equalized by moisture and air moving in from outside. If the container is heated up, the opposite can happen. But it is easy to see how a repeated cycle of breathing can lead a build-up inside the container of moisture, especially if the packing material is absorbent.

 

Before you place your items into a Shipping Container, ensure that the interior is dry. Begin by locking your eyes. Then, open the container with one hand. Move to the side walls and then to the back. Any holes should be easily visible. You should check that the seals on your container doors are weatherproof and secure. They have a dual seal. The outer seal stops water from entering via wind or wave. The inner seal keeps water from entering the container. If that happens, the water will drain around the door frame, allowing it to drain out of the bottom. Make sure you check the top seal and the side seals.

 

Dampstick Poles, a product developed by our research to reduce moisture in storage containers, can be used on the interior of the container. It is recommended that you place at least two Dampstick Poles into a 20' container. If you plan to store your goods for a prolonged period of time, it is important to exchange used Dampstick Poles at least once every three to six months. Nearly all Shipping Containers include these on the ceiling perimeter, as well as the floor, for cargo lashing. But, in the rare event that there are none, visit your local hardware store to purchase good quality stick on hooks. Clean the application spots, and hang the Dampstick from them.
