Adaptation of marine containers in extreme operating conditions

Protecting containers from high temperatures

When using containers in regions with hot climates, the problem of overheating the internal space arises. In conditions of elevated temperature, both the containers themselves and the cargo stored in them can suffer. Here are some measures to protect containers from heat:

• Thermal insulation: Installing thermal insulation materials on the walls and ceiling of the container is one of the first solutions to reduce the temperature. Depending on the budget and operating conditions, you can use fiberglass, polyurethane foam or mineral wool. These materials will help reduce heat transfer and maintain a more stable internal temperature.
• Reflective coating: White or reflective coatings on the outside of the container can reflect the sun's rays and significantly reduce heat. Special thermal paints are suitable for this, which create a protective layer on the surface and increase the resistance of the container to ultraviolet radiation.
• Ventilation: In hot climates, it is essential to install vents to help circulate air inside the container. Forced ventilation using fans or air conditioners can also significantly reduce temperatures. At the same time, it is worth providing protection against the penetration of insects and dust by installing meshes on the ventilation grilles.
• Solar panels and air conditioning: In regions with intense solar radiation, solar panels can be installed on the roof of the container to provide energy for cooling systems such as air conditioners. This solution is suitable for containers used as living or working spaces.

Adaptation of containers for operation at low temperatures

Severe frosts also pose a serious threat to containers. Metal becomes brittle at low temperatures, which can lead to cracks and seal failure. In addition, freezing of the internal space affects the storage of goods. The following methods are suitable for use in cold climates:

• Thermal insulation with condensation protection: To prevent the formation of condensation, which can freeze on the inner walls, the container is insulated using materials that are resistant to moisture formation. The use of polyurethane foam or special thermal panels will preserve heat and minimize the risk of moisture.
• Electric heaters: For containers intended to store temperature-sensitive cargo, the installation of electric heaters is recommended. Infrared heaters or heat guns powered by generators will help maintain the optimal temperature inside the container.
• Door seal protection: Cold weather can make the door seals less flexible, which will compromise the seal. Installation of frost-resistant seals made of high-quality rubber allows you to maintain tightness even at extremely low temperatures. Also, to avoid freezing of door locks, it is worth treating them with antifreeze.
• Additional roof or canopy: In heavy snow conditions, it is helpful to install an awning or additional roof over the container to prevent snow from accumulating on the top of the container. This will prevent the container from deforming under load and extend its service life.

Preparing containers for use in high humidity conditions

High humidity is one of the main causes of container corrosion. Containers used in coastal areas are especially susceptible to salt and humid air. To avoid rust and damage to the cargo, additional measures must be taken:

• Anti-corrosion treatment: Using anti-corrosion paints and coatings on the outer surface of the container helps protect it from rust. Special epoxy and polyurethane coatings are resistant to moisture and protect the container from corrosion.
• Desiccants and moisture absorbers: Installing dehumidifiers inside the container or using moisture-absorbing bags helps keep humidity levels low, preventing mold and corrosion. This is especially important for containers that store moisture-sensitive products, such as textiles, electronics and wood products.
• Sealing seams: In conditions of high humidity, it is necessary to carefully seal all seams of the container. Using a quality sealant will prevent moisture penetration and extend the life of the container. Particular attention should be paid to door seams, corner joints and places where elements are attached.
• Moisture-proof ventilation systems: The use of ventilation protected from moisture penetration avoids air stagnation. Such systems are equipped with special valves that prevent water from entering inside, but at the same time help remove moist air.

Combined solutions for extreme climate conditions

For the operation of containers in areas with changing climates, where both extreme heat and frost or high humidity are possible, it is recommended to use combined measures. For example:

• Universal thermal insulation: The use of insulation that is resistant to both heat and cold will help adapt the container to different conditions. There are modern thermal insulation materials that maintain stable temperatures under any climatic conditions.
• Double-layer walls: Installing double walls with an air gap helps create a “thermos effect”, allowing you to protect the container from sudden temperature fluctuations. The interior space remains more stable, which is useful for storing temperature-sensitive goods.
• Flexible heating and ventilation systems: The use of modern climate systems with heating and cooling functions allows you to maintain comfortable conditions inside the container at any time of the year.
