Hey there! As a container desiccant supplier, I've seen firsthand how crucial it is to properly install desiccants in containers. Moisture can be a real pain in the you - know - what when it comes to shipping and storing goods. It can cause mold, mildew, rust, and all sorts of other problems that can damage your products. So, in this blog, I'm gonna walk you through how to install container desiccant in a container.
Why Use Container Desiccants?
Before we get into the installation process, let's quickly talk about why you need container desiccants in the first place. Containers are often exposed to different humidity levels during transit. For example, when a container moves from a cold region to a warm one, the temperature change can cause condensation inside the container. This moisture can wreak havoc on your goods.
Desiccants work by absorbing this excess moisture. They act like little sponges, pulling the water vapor out of the air inside the container. This helps to keep the environment inside the container dry and protects your products from moisture - related damage.
Types of Container Desiccants
There are different types of container desiccants available, but one of the most effective ones is calcium chloride desiccant. Calcium chloride desiccants are known for their high moisture - absorption capacity. They can absorb up to 300% of their own weight in moisture, which is pretty amazing!


You can find calcium chloride desiccants in different forms, such as Calcium Chloride Desiccant Sachet, Calcium Chloride Desiccant Packs, and Calcium Chloride Desiccant Packs For Boxes. Each form has its own advantages and is suitable for different situations.
Pre - installation Preparation
Before you start installing the desiccants, there are a few things you need to do. First, make sure the container is clean and dry. Remove any debris, dirt, or standing water from the container. This will ensure that the desiccants can work effectively.
Next, you need to determine how many desiccants you'll need. The amount of desiccant required depends on the size of the container, the type of goods being shipped, and the expected humidity levels during transit. As a general rule of thumb, for a standard 20 - foot container, you might need around 10 - 15 packs of desiccants. For a 40 - foot container, you'll probably need 20 - 30 packs.
Installation Process
Step 1: Choose the Right Location
The location where you place the desiccants is very important. You want to place them in areas where moisture is likely to accumulate. One of the best places to install desiccants is near the container doors. This is because when the doors are opened and closed, outside air enters the container, bringing in moisture. By placing desiccants near the doors, you can quickly absorb this incoming moisture.
You can also place desiccants along the walls of the container. Make sure to distribute them evenly so that the moisture is absorbed uniformly throughout the container.
Step 2: Hang or Place the Desiccants
Most calcium chloride desiccant packs come with a hanging mechanism, such as a hook or a string. If your desiccants have a hanging option, use it to hang them from the container ceiling. This allows the desiccants to be exposed to the maximum amount of air, increasing their moisture - absorption efficiency.
If you're using desiccant packs that don't have a hanging mechanism, you can place them on pallets or on the floor of the container. Just make sure they're not blocked by the goods, so they can still interact with the air.
Step 3: Consider the Goods
If your goods are packed in boxes, you can also place Calcium Chloride Desiccant Packs For Boxes inside the boxes. This provides an extra layer of protection for the individual items. Make sure to place the desiccant packs in a way that they don't come into direct contact with the goods, as some desiccants might leave a residue.
Post - installation Checks
After you've installed the desiccants, it's a good idea to do a quick check. Make sure all the desiccants are properly placed and not damaged. You can also use a humidity sensor to measure the humidity levels inside the container. This will give you an idea of how well the desiccants are working.
If you notice that the humidity levels are still high after a few days, you might need to add more desiccants. On the other hand, if the desiccants are completely saturated (you can tell if they're heavy or have changed in appearance), you can replace them with new ones.
Maintenance
During the transit or storage period, keep an eye on the desiccants. If the container is going to be stored for a long time, it's a good idea to check the desiccants periodically. You might need to replace them if they've reached their maximum absorption capacity.
Conclusion
Installing container desiccants is a simple but important step in protecting your goods from moisture damage. By following the steps I've outlined in this blog, you can ensure that your container has a dry and safe environment for your products.
