How to eliminate moisture in a shipping container
Shipping containers are an integral part of global trade, but their use also poses some challenges. One of the biggest challenges is humidity, which can damage cargo and cause mould growth and corrosion. In this article, we’ll outline the best methods to eliminate moisture in a shipping container.
1. Use of air dryers
One of the most effective methods to eliminate moisture in a shipping container is the use of air dryers. Air dryers, such as CaCl2 dry pole air dryers, are designed to absorb moisture from the air and environment in the container.
Advantages of CaCl2 desiccant dryers
- High efficiency: calcium chloride (CaCl2) has a proven ability to aggressively remove moisture.
- Easy installation: the dryers can be easily placed in the container.
- Long-term effect: One pack can work for a long time, ensuring lasting protection.
2. Container leak check
The next step to eliminate moisture is to ensure that the container is tight. Even small leaks can allow moisture to enter, which can lead to problems.
How to check for leaks
- Visual inspection: Inspect all joints and seals of the container.
- Water test: Spray the container with water and check for leaks.
- Pressure test: use the pressure test to detect leaks that are not visible to the naked eye.
3. Use of ventilation
Proper ventilation can also significantly reduce the humidity level inside the container. Ventilation holes can help remove moist air and bring in dry air.
Types of ventilation
- Passive ventilation: simple openings that allow natural air circulation.
- Active ventilation: fans or other mechanical systems that actively remove moisture.
4. Use of moisture absorbers
Moisture absorbers such as CaCl2 container bags are another effective solution for moisture removal. These bags can be placed at various locations inside the container and absorb moisture.
Benefits of using moisture absorbers
- Easy application: the bags are small and can be placed anywhere in the container.
- Effective absorption:CaCl2 is known for its high moisture absorbing capacity.
5. Regular maintenance and inspection
Regular maintenance and inspection of the container can help prevent moisture problems. Inspect the container before each use and make sure all moisture elimination methods are working properly.
What to check
- Seals and joints: make sure all seals are in good condition.
- Dryers and absorbers: check that the dryers and absorbers are not full and are working properly.
- Ventilation: make sure the ventilation systems are not blocked and are working properly.

Do Shipping Containers Catch Fire?
A shipping container itself does not catch fire, but its robust and tight construction makes it an ideal environment for catastrophic fires to start and escalate if there is flammable or reactive cargo inside. The problem of container ship fires is complex and requires the cooperation of the entire logistics chain – shipper, carrier, shipping company and regulator. The key to greater safety is strict compliance with regulations, technological innovation and a responsible approach – trying to save on declaration can lead to losses in the hundreds of millions and endanger human lives.
How to Properly Choose a Shipping Container?
Choosing the right shipping container is a complex decision influenced by the purpose of use, budget, desired lifespan and legislative requirements. Always set clear priorities, call for a personal inspection, verify the history of the container and the seller’s references. Investing in a higher quality container will pay off in lower maintenance costs, longer lifespan and higher safety. If you are planning to convert to a residential or commercial building, do not forget about the need for a building permit, floor modifications and ensuring insulation against moisture and temperature fluctuations.
Grid – ABS Vent Cover
The ABS Vent Cover is a key structural element found on the outside of standard dry vans. Its main function is to allow passive air exchange between the interior and exterior of the container.
Faults and Most Common Defects of Refrigerated Containers
Refrigerated (freezer) containers are the backbone of safe and efficient transport of temperature-sensitive goods. Thanks to modern technologies, consistent maintenance and remote monitoring, their failure rate can be significantly reduced. The most common defects – from temperature fluctuations to mechanical and electrical failures to human errors – can be solved through systematic prevention, regular inspections (PTI), operator training and the use of telematics.
