Air Ventilation – Shipping Containers

Your container needs ventilation for air flow

The container industry has developed from providing a unit to transport goods into a market where these units are applied for various tasks. These applications are both for business and personal use. In size and strength these containers are ideal. They do lack in one area though: ventilation. This is a vital aspect no matter what the container is used for.

When cargo is shipped, the airtightness of the container adds to its value. Cargo owners don’t want air, moisture or even insects to be able to get inside in the brief time the assets are being transported. When containers are applied for other uses, being airtight might actually create problems and this must be tended to through ventilation which is installed expertly.


What happens without ventilation?

While transported goods are taken from containers as soon as possible, items stored in containers may undergo long periods without being moved or even being opened. When containers are used for housing, you would want a comfortable atmosphere for everyone using the space. Because a container starts out as being airtight, it’s not ideal for these uses. Condensation takes place over time which can ruin merchandise of various kinds. If you’re living inside such a unit, the unmoving air can become quite severe. Only if you reduce temperatures and create natural air flow through a system which is installed expertly will you be able to combat these effects.

The dangerous effect of an airtight container

An airtight space over long periods of time has certain consequences. This includes:

  • Condensation: Whenever there is a big fluctuation between day and night time temperatures, condensation will appear. This is moisture that appears against the inside of the container. In extreme circumstances it can be similar to raindrops which fall down. For housing, this can become quite irritating circumstances. For storage, anything from electronics to food and even paper can be damaged or destroyed by the constant presence of water.
  • Rust: The presence of water creates the chance of rust, whether it’s on the item’s inside or the container itself.
  • Mould: The presence of moisture, mixed with the high temperatures created by steel baking in the sun, gives ideal conditions for the growth of mould. This spells disaster for perishables, paper and many other valuable commodities.
  • Heat build up: The steel from which containers are made absorbs heat and in direct sun this unit can become much like an oven. Once again, for use as housing or offices this is simply not safe or comfortable, as it may lead to exhaustion and does not create an ideal working environment. If you don’t reduce temperature, it can also damage stored food and when the container houses flammable substances, high temperatures may create very dangerous situations where these gasses or liquid can explode.
  • Fumes: In an airtight container there are no passages for poisonous fumes to escape or to minimise odours. People working inside such a container is at high risk of being affected by these fumes and odours are an unwelcome factor in any house or working area.
    So what do we do?



Luckily there are various ways to reduce temperature and curb moisture formation through natural air flow. These ventilation systems can be expertly installed or even implemented by container owners themselves. The system’s cooling effect can be enhanced by insulation of the whole container. While any one of these units will already make a big difference, the ideal way is to create a system where two or more units work together. Your options include:

  • Small and large steel louvered vents: Vents work at their best when you install them on opposite sides of a container. This allows for wind to push fresh and dry air into the unit, but also for hot air to escape through the opposite wall’s air vent to create natural air flow and reduce temperature.
  • Whirlybirds: These turbine vents are installed on top of a container and can be powered or simply work with a little help from the wind. The turbines pull hot air filled with moisture out of the container, allowing cooler air that has less moisture to go back in.

Customise your container to make it work to its full capacity

You know what purpose you want your container to fulfil. You can make sure through expertly installed vents that a natural air flow occurs throughout the unit. This will assist in creating the ideal circumstances to keep people comfortable or assets safe. Because ventilation units are quite versatile in their application, your container can be customised to fit your requirements exactly.
