Shipping containers are commonly used for storing a variety of items. They provide a secure and weather-resistant storage solution that you can easily transport from one location to another. However, depending on what is being stored inside, ventilation may be needed. Storage container ventilation is essential for several reasons. It helps to control the temperature and humidity levels inside the container, preventing condensation and mold growth. It also helps to prevent the buildup of gases or fumes that could harm people or items stored inside.

When should you add ventilation to a storage container? The answer depends on what you plan to store inside and how long you plan to keep it. In this blog, we delve into everything you need to know about ventilation options for your steel container.

What Are You Storing?

Ventilation is essential if you are storing items susceptible to moisture damage, such as textiles, paper, or electronics. Without proper ventilation, moisture can accumulate inside the container and cause mold, mildew, and other types of damage. This is particularly true if the container is located in a humid or damp environment. In this case, consider adding vents to the container to allow airflow and prevent moisture buildup.

Similarly, ventilation is critical if you are storing items that produce gases or fumes, such as chemicals or fuels. These things can be dangerous if not stored correctly and in a well-ventilated area. The buildup of gases or fumes inside the container can create a hazardous environment and pose a risk to anyone who enters. In this case, consider adding vents to the container to allow the safe dispersal of any gases or fumes.

You probably don’t need ventilation in your container when you store outdoor equipment, such as tools or sports gear. That’s because these items are not sensitive to outside temperatures, so that they won’t be affected by temperature too much.

How Long Are You Storing It?

Another factor to consider is the length of time that you plan to store items inside the container. If you are storing items for an extended period, ventilation is important to ensure the container remains fresh and free of musty odors. Over time, stagnant air can develop inside the container, leading to unpleasant smells and potential health hazards. By adding vents, you can promote fresh air circulation and prevent any buildup of stagnant air.

Where Are Your Storing It?

It’s also important to consider the climate in which you will store the container. Ventilation becomes even more critical if you keep items in a hot or humid environment. High temperatures and humidity levels can accelerate the growth of mold and mildew and can also cause objects to deteriorate more quickly. By adding vents, you can help to regulate the temperature and humidity levels inside the container, preventing damage to your stored items.

Proper Storage Container Ventilation

Proper ventilation is key for maintaining a safe and comfortable interior environment in a storage container. The container can become hot, humid, and prone to mold growth without adequate ventilation. When placing ventilation in a storage container, you must consider several factors.

Placement for Cross-Ventilation

Ventilation should be placed in a manner that promotes cross-ventilation. This allows air to circulate throughout the container, preventing stagnant air pockets. To achieve cross-ventilation, vents should be placed at opposite ends of the container or on opposite walls.

Placement for Air Flow

Ventilation should be placed in areas that promote airflow. This means putting vents at the highest point of the container to allow hot air to escape and at the lowest point of the container to allow cool air to enter. Placing vents in the middle of the container may not promote proper airflow.

Size and Number of Vents

The size and number of vents required will depend on the size of the container and the intended use. Generally, a minimum of two vents is necessary to promote cross-ventilation. The size of the vents should be calculated based on the cubic feet of the container, with a recommended minimum of 1 sq ft of vent space for every 150 sq ft of floor area.

Types of Shipping Container Vents

There are several types of vents, including passive vents, active vents and air conditioning units. Passive vents are the most basic and affordable option, relying on natural airflow to promote ventilation. Active vents, such as solar-powered or electric, use powered fans to promote ventilation. Air conditioning units can provide ventilation and temperature control but can be expensive to install and operate.

Choosing the Right Storage Container Ventilation

There are several types to choose from when it comes to storage container ventilation. Each type has its benefits and drawbacks, and the choice will depend on the specific needs and requirements of the user. Below, we highlight the most common types of shipping container ventilation that we offer at Southwest Mobile Storage.

Roof Turbines

Wind turbines installed on the roof can be a viable option for providing ventilation in a storage container. They harness wind energy to power a fan or ventilation system, providing a consistent air flow to the container. This can help to reduce humidity, prevent mold growth, and maintain a comfortable interior environment.

Wind turbines can be particularly useful in areas with consistent wind patterns, such as coastal or high-altitude locations. They can also be cost-effective and eco-friendly, as they do not require electricity and can be powered solely by wind energy.

When installing wind turbines for ventilation in a storage container, it is vital to consider the size and placement of the turbines. The size of the turbine should be matched to the size of the container and the intended use, with consideration given to the expected wind patterns in the area. The placement of the turbines should also promote cross-ventilation and airflow within the container.

Fixed Louvers

Fixed louvers are a popular and effective option for providing ventilation in a storage container. Louvers allow airflow in and out of the container while also preventing rain and debris from entering. Fixed louvers are stationary, meaning they do not require power or maintenance. They are generally made from durable materials like steel or aluminum and can be customized to match the size and design of the container.

When installing fixed louvers, it is crucial to consider the placement and size of the louvers. Louvers should be placed for cross-ventilation and airflow, with consideration given to the size and intended use of the container. The louvers should also match the size of the container, with a recommended minimum of 1 sq ft of vent space for every 150 sq ft of floor area.

Exhaust Fans

Exhaust fans can be an effective option for providing ventilation in a storage container. These fans are designed to pull hot or humid air out of the container, promoting airflow and reducing the risk of mold growth or excessive heat buildup. Exhaust fans can be handy in areas with high humidity, heat, or containers used for industrial or agricultural purposes. They can be powered by electricity or solar energy and customized to match the size and design of the container.

When using exhaust fans to ventilate a shipping container, it is essential to consider the size and placement of the fans. The size of the fan should be matched to the size of the container and the intended use, with consideration given to the expected heat load or humidity levels in the area. The fan placement should promote air flow and cross-ventilation within the container, with care given to the fan blades’ orientation and the airflow’s direction.

Air Conditioning

While air conditioning units are designed to cool the air, they can also provide ventilation in a shipping container. By circulating the air and removing humidity, air conditioning units can help to maintain a comfortable and safe interior environment.

When using an air conditioning unit to provide ventilation in a shipping container, it is crucial to consider the size and power requirements of the unit. You should match the size of the unit to the size and intended use of the container, considering the expected heat load and humidity levels in the area. The power source for the unit should also be considered, with options ranging from electricity to solar power.

Air conditioning units can be beneficial in containers used for industrial or agricultural purposes, as they can help maintain a consistent interior temperature and prevent heat-related damage to equipment or products. They can also be a valuable addition to living or work spaces within the container, providing occupants with a comfortable and safe environment.
