Cargo containers are widely used for transporting goods across long distances and are designed to be weathertight. However, containers are also being used in increasing numbers for workspaces, living spaces, and other unique applications and require, or at least benefit from, increased ventilation. They can suffer from moisture buildup, temperature fluctuations, and condensation without proper container ventilation.
Importance of Ventilation
Installing shipping container ventilation systems improves air quality and controls temperature for inventory and people. Ventilation also reduces moisture, helping to retain a shipping container’s structural integrity.
- Moisture Control: Containers can experience significant temperature changes during transportation, leading to condensation. Proper ventilation helps control moisture levels, preventing mold, mildew, and corrosion.
- Temperature Regulation: Ventilation assists in maintaining a stable temperature within the container, protecting temperature-sensitive goods from extreme heat or cold.
- Air Quality: Good ventilation ensures a continuous flow of fresh air, vital for certain types of cargo, such as perishable goods or items requiring specific atmospheric conditions.
- Toxicity: Adding proper shipping container ventilation allows the dispersal of VOCs (Volatile organic compounds) that can be dangerous or unhealthy if allowed to build up.
Shipping Container Vents
- Passive Vents
- These simple, non-mechanical vents allow air to circulate naturally. They are easy to install and require minimal maintenance. Examples include louver vents and mushroom vents.
- Active Vents
- These use fans or blowers to move air in and out of the container actively. They are more effective in controlling temperature and humidity but require a power source and regular maintenance.
Air Conditioning for Shipping Containers
- Installing an AC unit on a storage container can transform it from a simple storage space into a comfortable, climate-controlled environment suitable for many uses: offices, living spaces, and sensitive inventory.
- The type of AC unit depends on the container’s size and use:
- Window Units: Suitable for smaller containers or when a single room needs cooling.
- Portable Units: Flexible and easy to install but generally less efficient for larger spaces.
