Why Condensation Forms in the Container

During transport and storage, considerable temperature variations occur inside freight containers. Temperature differences of several tens of degrees Celsius can occur between day and night, not only at ports and stations located in different climatic zones but also during storage in the container at a fixed location. As warm or warm air can absorb much more moisture than cold air, temperature drops in airtight cargo containers lead to the formation of condensation and, thus, phenomena such as container sweat, container rain and cargo sweat.

What is container rain?

Container rain is condensed water that forms on the interior surfaces of the container. Due to the surface tension, the water that accumulates there concentrates into increasingly larger drops, drip off due to their weight. The resulting rain of containers then falls directly on the cargo.

What is container sweat?

Container sweat caused by falling outside temperatures usually occurs below the container ceiling. This effect occurs when the container wall cools significantly during transport to colder climates or nighttime temperature drops due to cold ambient air. Moisture is thus extracted from the significantly warmer air in the container and accumulates on the ceiling and walls of the container.

What is Sweat Loaded?

Cargo sweat is formed by solar radiation during transportation from a cold to a warm environment or when a shipping container that has cooled overnight heats up. If the air in the container heats faster than the cargo, the moisture in the air will condense on the surface of the cargo, packaging and packaging aids under these conditions.

Possible damage due to condensation water in the container

Condensation water in the container can cause a variety of damage. For example, the sweat of the container and the sweat of the cargo can lead to corrosion and rust, mold on the packaging and the goods, softened cardboard and lose labels.

Corrosion/rust on transported goods

If condensation forms in the container, this leads to a high risk of corrosion, especially for steel cargo elements. This applies to materials sent for further industrial processing and finished products. Condensation water must be effectively and safely bound so that the cargo is not attacked by rust and possibly destroyed during sea transport.

Condensation water in the container causes the transported steel goods to rust.

Mold on packaging and goods

Especially in the food industry, mold formation during transport must be avoided at all costs. However, if no appropriate countermeasures are taken in the container, the sweat produced at sea quickly creates a climate in which mold can form on packaging and goods and quickly spread.

Condensation water in containers promotes the growth of mold on packaging and goods.

Damage to packaging caused by humidity

Even though cargo cannot rust and is relatively immune to mold, it can be severely damaged and even rendered unusable by condensation in the cargo container. Humidity in the surrounding air condensing directly on the packaging materials or rain falling from the container ceiling can soften the cartons at sea and detach the labels.

Condensation in the container causes damage due to moisture in the packaging.

This is how container dehumidification works.

The conditions under which moisture in the container becomes a serious problem and can cause devastating damage to cargo vary widely. It is, therefore, very important to determine precisely which countermeasures are necessary in each case so that in a second step, the condensation of the container can be combated as specifically and effectively as possible.

THE PROCESS STEPS APPLIED BY THOMAR FOR THE OPTIMAL USE OF DESICCANTS

STEP 1: ANALYSIS

Identify the exact need for countermeasures.

The need to take appropriate measures to prevent the formation of condensation water in container transport depends on many factors. The goods transported, the climatic zones served, the size of the containers, the weight and moisture content of the goods, the packaging aids used, the duration of storage and transport and other parameters all play a very important role. Various. For this reason, the individual requirements for a particular application can only be determined in cooperation with container dehumidification experts.

STEP 2: PRODUCT SELECTION

Avoid container condensation due to desiccants.

We offer container desiccant against condensation water in the container exclusively produced in our production in UK. We attach great importance to meeting the highest standards regarding product quality and working conditions. For optimum efficiency of the desiccant used for container dehumidification, the loaded container's spatial conditions must be considered. That's why we train our customers' employees to select and place desiccants optimally in each application.

STEP 3: PRACTICAL INPUT

Effectively combat condensation water in the container.

To effectively and safely prevent the formation of condensation water in the container, it is not only necessary to use suitable desiccants in adequate quantities. Therefore, we offer our customers a comprehensive service for container dehumidification: individual needs analysis, competent advice, targeted product selection and intensive training. If necessary, we carry out test series, review the entire logistics process and provide practical support for optimization. The goal is always 100% effectiveness of all measures.

At Britwrap, We offer best quality container desiccant bag which can absorb all humidity in shipping container.
