Does My Storage Container Need Ventilation?

Does My Storage Container Need Ventilation?

Shipping containers are originally manufactured to hold cargo material as they travel across the ocean. Small vents are included in the original design of traditional shipping containers and they act as pressure vents that promote air circulation as the containers travel – although very minimal air circulation.

Many organizations choose to repurpose shipping containers into storage units, often remaining unmodified. Other times, highly sensitive equipment or temperature sensitive items are stored in repurposed shipping containers, requiring modifications to properly store and protect items. Shipping container ventilation, or other temperature control measures, play a major role in the protection of the items stored in the container.

When You Need Storage Container Ventilation


Passive Vent Modification

If you plan to store non-temperature sensitive equipment or items in a location with a moderate climate, the existing vents may work fine for your purposes. Keep in mind these small vents only promote minimal air flow. Some items that may be alright to store in this condition could include lawn equipment, athletic equipment, or other items not sensitive to climate changes. Although even some of these items listed may be deemed temperature sensitive, depending on your particular equipment.

If you wish to better protect stored items, you’ll likely need to modify the container to better suit your needs. This can be done in three methods.

  1. Install new, upgraded vents
  2. Add insulation to your storage container
  3. Add climate control through air conditioning systems

Upgrade Storage Container Ventilation


Active Vent Modification

If your organization needs better air flow, consider installing more effective vents than those the manufacturers include. Larger, more specialized vents can be added to a shipping container at the top or bottom of the unit. If you’re concerned about moisture buildup in your storage unit, consider adding active ventilation, which provides air circulation using mechanical fans. These vents will also work against odors. Passive vents, on the other hand, rely on the natural air currents caused by the weather. Keep in mind active vents require an electrical connection.

Add Insulation


Spray Foam Insulation

If you wish to keep stored items at a more moderate temperature, consider adding insulation to your storage container. Insulation will protect stored contents against temperature changes both hot and cold, keeping the interior at a more moderate temperature. Insulation options that work well for storage include Styrofoam or spray foam, neither of which require framing.

Add Climate Control



Finally, if you need to keep stored material at a set temperature, consider adding an air conditioning system. Select from several types of A/C units, including a PTAC unit, a wall-mounted unit, or window unit. These different units will give you varying levels of control, depending on the sensitivity of your stored items. With an air conditioning unit, you can feel confident that no matter how the weather changes, your storage space will remain at an ideal temperature.
