How to keep a shipping container from getting wet

Container Desiccant


Even though you can't completely stop moisture from building up, there are ways to keep condensation from getting out of hand in your cargo container.

Use the right pallets

Using pallets to store your products is common, but it's important to think about the amount of moisture in varieties of wood. The decking industry is under pressure to provide decking quickly, requiring fresh wood, often overloaded with moisture content. If wood is used while damp, it can add moisture to the air and worsen condensation in the shipping container. Your decks may not be new but were made from old wood stored in cool, damp places during cold winters. These pallets are probably just as full of moisture.

Plastic pallets can help reduce condensation from the shipping container, as they do not absorb moisture from the air. If you need to use wooden pallets, make sure these pallets are dry before loading.

Use desiccants

Desiccants absorb excess water from the air, effectively lowering the inside of the container's dew point. Desiccants are often put inside a shipping container by the shipping company to reduce the amount of moisture that comes from the products, the packaging, or changes in temperature.

There are many different kinds of desiccants. Depending on what you want and the goods in your load, you can choose from the following types of desiccant:

  1. Container Desiccant Container desiccant absorb moisture in a shipping container and can be hung from the ceiling and walls to help keep the air dry. As the desiccant absorbs water, it lowers the dew point temperature. This keeps condensation from forming on the walls of the container.
  2. Desiccant Blankets – This type of desiccant is placed or hung over the top of the products in the container. It is designed to prevent condensation from accumulating in the air and protects covered merchandise from water droplets. These blankets have a membrane that lets air pass through moisture from the merchandise to seep upwards through the blanket while offering a leak-proof design that prevents moisture from settling in, also container rain. Some desiccant blankets are made to make an airtight environment that keeps moisture out. hot or cold air from flowing through the container, thus reducing temperature changes that could cause condensation.
  3. Desiccant Pads – Desiccant wipes are essential when shipping refrigerated goods or beverages. These pads are placed under the merchandise itself; In the event of a leak, the pad absorbs additional moisture to prevent precipitation inside the container and the proliferation of fungi. Many desiccant pads come with a thermal barrier that keeps the temperature of the container to prevent moisture buildup.

If you want to know how to get condensation out of cargo containers, desiccants could be an important part of the equation. Desiccants can help prevent condensation buildup, but you must use the correct material and amount of material to protect your cargo properly.

Consider dehumidifiers

Consider getting a dehumidifier if you need to know how to stop condensation from forming in a cargo container that you're going to store. If your shipping container has a strong power source, you can use a dehumidifier to remove moisture from the air. Don't forget that you will need to empty the dehumidifier of water on a regular basis or set up a hose system that can pull the water out of the container.

Make the house warmer

When you insulate your shipping container, you can cut down on the amount of moisture in the air and stop rain from getting into the container. Also, container insulation can keep your cargo warmer than the dew point, which prevents condensation from happening when temperatures are too different.

Improve ventilation

Proper ventilation can reduce condensation by equalizing indoor temperatures with outdoor temperatures. Ventilation channels hot, humid air out of the container, while outside air with the same room temperature is drawn in. Humidity is reduced when indoor temperatures are nearly the same as outdoor temperatures.

There are many ways to install ventilation in a shipping container; However, ventilation is not always the answer. If you're shipping goods in areas that normally have humid conditions, ventilation could push out moist air and worsen condensation. If operating in humid climates, avoid using ventilation to stop condensation in a shipping container.
