Combatting Moisture in Shipping Containers

Tips for Reducing Moisture in Shipping Containers

Condensation and moisture in shipping containers can significantly threaten the integrity of your containers, often damaging the stored goods. Jennings Containers, a leading provider in the shipping container industry, shares essential strategies to effectively manage humidity and ensure the longevity of your container. 

1. Thorough Waterproofing: Ensuring Complete Protection

The first and foremost step in reducing moisture in shipping containers is ensuring your container is fully waterproof. It’s essential to regularly inspect every inch of the container for signs of wear, damage, or rust, which are common causes of leaks. These inspections should be thorough and include checking the roof, doors, and all seams and joints. 

Immediate repair of any discovered issues is crucial, as this not only prevents water ingress but also significantly extends the lifespan of the container. A well-maintained container is less prone to moisture-related problems and ensures better protection of the contents stored within.

2. The Role of Desiccants in Moisture Control: A Dry Solution

Desiccants play a pivotal role in regulating the moisture in shipping containers. These materials are incredibly efficient at absorbing excess moisture from the air. By strategically placing desiccant packets or bags in various locations inside the container, such as near doors and vents, you can significantly lower the internal humidity levels. 

This proactive approach is especially beneficial for protecting sensitive items like electronics or clothing from moisture damage. Regular replacement or recharging of desiccants is recommended to maintain their effectiveness over time.

3. Importance of Adequate Ventilation: A Breath of Fresh Air

Adequate ventilation is critical in managing the internal climate of a shipping container. Installing vents on opposite sides of the container creates a crossflow of air, effectively removing warm, moist air and replacing it with cooler, drier air from outside. 

This natural air exchange is vital in preventing the build-up of condensation, which can damage the container’s structure and contents. In addition to fixed vents, consider using vented doors or installing roof turbines to enhance air circulation further.

4. Utilising Electric Dehumidifiers: Active Humidity Management

In environments with high humidity levels, or during extended periods of storage or transit, electric dehumidifiers are a must-have. These devices actively extract moisture from the air inside the container, maintaining a controlled and safe humidity level. 

This is particularly crucial for protecting goods that are sensitive to moisture or in geographical areas where humidity levels are consistently high. Regular maintenance of these dehumidifiers ensures their efficiency and longevity in protecting your container’s contents.

5. Insulating for Consistent Temperatures: Keeping It Stable

Proper insulation is critical in maintaining a consistent internal temperature within the container and mitigating condensation risks. Insulation materials, such as foam or reflective panels, can be applied to the container’s walls and ceiling to minimise the temperature fluctuations that often lead to moisture issues. 

This not only protects the goods stored inside from the extremes of hot and cold but also contributes to energy efficiency if the container is climate-controlled.

6. Monitoring Humidity Levels: Staying Vigilant

Regular monitoring of the humidity levels within your container is crucial for early detection and prevention of moisture-related problems. Utilising hygrometers or similar measuring devices helps in keeping a close eye on the internal conditions. 

Additionally, the practice of periodically opening the container doors to ventilate the space can be very effective, especially when the container is stationary for extended periods. This practice allows for a change in air and helps in keeping the internal environment healthy and moisture-free.

The Benefits of Using Absorpole In Your Shipping Container

Containers locked for extended periods can be prone to condensation, potentially damaging the goods inside. To mitigate this, it’s crucial to store only dry items and regularly air out the container by opening its doors. Additionally, consider using Absorpole, an effective solution to combat condensation-related issues. 

Absorpole, utilising the moisture-absorbing properties of calcium chloride, is designed to fit snugly within the container’s corrugated recesses, taking up minimal space and avoiding damage during loading and unloading. Activated by pulling out of its container, Absorpole starts absorbing moisture immediately, with the calcium chloride transforming into brine that is collected and prevented from re-evaporating.

Absorpole is particularly effective due to calcium chloride’s superior moisture absorption capacity, making it ideal for protecting cargo over long voyages or for extended periods in static containers. Depending on the container size, usage varies – typically 4-6 units for 20-foot containers and 6-8 for 40-foot ones, with adjustments based on voyage length, temperature variations, and cargo type. For static use, just two Absorpoles are sufficient. 

These products are made from non-toxic, recyclable materials and can be disposed of with regular waste. Absorpoles are easy to install and remove and available for purchase through our online shop or by phone, offering an accessible and efficient way to safeguard your container’s contents.
