Storing these Items? Consider Ventilating Your Shipping Container

By April 15th, 2016 About Containers 5 Comments

At Container Technology Inc. (CTI), we spend a lot of time and effort helping people decide between the different types of shipping container | storage container – different lengths, heights, and conditions. Sometimes even to the point that we lose sight of the most important part—what’s going inside the container itself! To ensure that your valuable items are properly protected, it is important to consider whether your shipping container has adequate ventilation.

A shipping container | storage container is more than just the giant metal box that it appears to be. Every shipping container is constructed to withstand the rigors of shipping on the open ocean. They can handle almost anything that is thrown at them—extreme weather, harsh physical environments – with ease.

But the very design and construction that makes the shipping container ideal for storage can also cause problems for your stored items. For example, if moisture gets into the container, then it can’t get out. While shipping containers | storage containers are built with small pressure vents that allow the unit to breathe, they are not sufficient to create functional ventilation inside the container.

For this reason, ensuring that you have adequate ventilation is essential. Proper ventilation becomes even more important if you are placing your container in an environment where temperatures fluctuate drastically or when you are storing temperature or moisture sensitive items.

The easiest way to ensure that your shipping container | storage container has the ventilation you require is to modify your container with a roof-top turbine vent, fixed louver vent, or exhaust fan. Just contact CTI to find out what option is best for you.

Shipping containers | storage containers have a variety of applications and we know that every client has different needs for their portable storage but if you are planning on storing any of the following items in your container, you may want to consider ventilation.

Household Items

If you are storing household items-proper ventilation is key, whether it’s for a remodel, move, donation drive, or other purpose. If any moisture reaches your items and is sealed inside your container without any air circulation – your items can warp, mold, and mildew. Temperature changes– such a extreme heat can also damage your items. Of course, proper packing of your household items can help, but they cannot guarantee protection like proper ventilation can.

Heavy Machinery & Automobiles

While heavy machinery and automobiles seem like they’re designed to stand up to heavy use and abuse, properly ventilated storage helps to ensure that they will run properly.

In order to keep your machinery in top condition and operating well, it is critical to keep it at a safe temperature range and allow air circulation. Extreme temperatures can undermine the integrity of your machinery and could even cause it to be damaged beyond repair. Additionally, if moisture is introduced to the shipping container and is sealed in, rust and mold could develop.

Automobiles contain flammable liquids and are made up of materials which can suffer from exposure to heat or moisture. Vehicle parts like engines, vehicle fluids, and delicate internal systems also require ventilated storage.

Dry Goods

Ventilation is a must when storing dry goods. In a sealed or poorly ventilated container, goods can gather condensation, which damages your product and can even cause rot. Adequate ventilation preserving your valuable goods can save money in the long run by helping to keep your container dry and cool.

Certain Chemicals/Pressurized Gases

If you work in construction or other types of heavy industry, chemicals and pressurized gases are everyday tools. Some chemicals are fine in an unmodified storage unit, but you will need a ventilated shipping container if you are storing chemicals that are flammable. Check the legal requirements for each chemical you are planning on storing before placing it in your storage container. There are certain chemicals that cannot be stored in an enclosed space under any circumstance.

Like chemicals, pressurized gas containers have a lot of legal requirements for their storage. To comply with the law, pressurized gas storage must maintain a safe temperature and be well ventilated. Check on the specific restrictions of your product before you plan on utilizing a shipping container.

    Hi Gywn,
    Thanks for finding us. I’m guessing that you are referring to our rooftop turbine vent. You may want to install a few of them on the roof of your container, to ensure adequate ventilation. The vent we use is a standard 12 inch rooftop turbine. It can easily be mounted to the roof of any container. We purchase the vents from a local Home Depot here in the US. However, they can also be purchased online through Grainger. If you would prefer to install vents in the sidewall of your container, you can utilize a wall mounted fixed louver vent. Installing one on each long wall of the container will allow for air to pass through your container. If you decide to go this route, make sure you purchase louver vents with a bird screen. Whichever way you go, you’ll need to cut a hole(s) in the roof or sidewall in order to mount the vent(s). If you install the vent in the roof, make sure the bottom of the vent is elevated above the exterior surface, so that water will not come over the frame and leak into the container. I hope this information is helpful. Please let us know if you have any questions. Thanks, Ray

    I just purchased what looks like a fairly new 20′ shipping container. The reason for the container, is to temporarely store a jeep, and some household items ( bed, tv, clothes,etc.) I am located in the Florida Keys. I am ready to install a 12 inch Turbine Vent. Will that alone be sufficient, along with the 2 vents that came with the container, to eleviate the heat build up ? Things to be stored will be for approximately from July, through November. Thank you for any advise.
