Regardless of the application, the use of our container desiccants serves the same purpose. Here are some of the most commonly asked questions and answers about our desiccants. For any other questions not covered here, please feel free to contact the DunLash team at any time.

How Do Container Desiccants Assist With Moisture Control?

Container desiccants are unique products that work by extracting water vapour from the surrounding air. In doing so, humidity inside the container is prevented from reaching condensation, preventing a build-up of moisture. We have two desiccants to choose from:

These can be suspended inside the container hanging from the upper D-Rings or placed on cargo, depending on the specific needs of the customer and products.

I Load And Seal My Container In Dry Conditions. Why Do I Still Need Moisture Control?

There could be a number of reasons for moisture control still being required. If you have used container desiccants, it is likely that not enough were allocated for your shipping container. However, many moisture issues can occur en route. A certain amount of moisture already exists in the container itself, in the products, and in the packaging, especially in wooden containers and pallets. There could be a case of packaging not being dried out significantly before travel. This moisture will gradually start to vaporise into the air, resulting in condensation, and container sweat or rain.

Aside from the above-mentioned factors, there is also the external climate. Containers can often travel through multiple climatic regions, changing temperatures as they go. This shifting in temperature can result in changes in the relative humidity, which can be the cause of condensation. Where this is expected, more container desiccants need to be added to bring the moisture content in the air down.

My Products Are In Tightly-Sealed Glass Jars. Why Do I Need Container Desiccants?

As mentioned above, even when your products are free of moisture, there are other ways for moisture to seep in. Packaging and the relative humidity inside the container itself can contribute to an excess of moisture in the air. Even though your products are securely packaged, excess moisture on a long voyage can result in mould, rusting, caking of powdered products, and collapsed packaging. Hanging container desiccants in the container with your sealed products will ensure that they are in perfect condition on arrival at their destination.
