Moisture and condensation are among the main causes of damage to goods transported in containers. How do they arise? What's the solution? Let's find out together Propagroup's desiccants.

Those involved in shipping goods and materials by sea know all about the damage caused by condensation inside containers. Let's find out together for which reasons it is created and which desiccants we can use to solve humidity problems.

What causes this condensation?

Condensation is the result of a combination of high levels of ambient humidity and the natural temperature fluctuations of day and night. It is caused by a rapid lowering of temperature, which causes water particles to change from a gaseous state to a liquid state. In simple terms, the moisture in the air becomes water.

If this happens on the inside of a car window during a storm or on a window at home, we can just take a cloth and dry it without consequences, but what might the consequences be when the same happens in a container on a 30-day sea voyage?

Did you know that more than 10% of goods transported by container suffer serious damage due to condensation?

A container transported by sea may take several weeks or months before arriving at its destination. Unless it is an expensive temperature-controlled container, environmental conditions on board are impossible to monitor and may cause damage - sometimes irreparable - to your goods. In a warm and damp environment, the most common problem is the rain effect, but others include the proliferation of molds and fungi.  

What can we do to prevent moisture turning into condensation?

It’s essential to enlist the aid of an expert who can accurately analyze your needs and advise you on how to reduce the moisture - the only variable that can be altered, since the other crucial factor, temperature, is also hard to control during transport. By reducing the amount of moisture inside the container, we can delay the dew point or condensation point; as described above, this is the point where moisture turns into liquid.

Propagroup specializes in protecting goods against moisture, and is at your disposal to provide scientific analysis and resolution of your problems, working with you to find the best solution for your shipment.

Thanks to more than 50 years' experience in the sector, Propagroup has developed various responses including the Propadry System, a range of extremely powerful desiccants, moisture absorbers, designed specifically for use in containers. The extraordinary absorption capacity of the Propadry tray means the amount of moisture present in the container can be effectively reduced throughout the journey, thus solving your problem.
