Damaging humidity problem such as container condensation problem container rain and cargo sweat will result in a lots of cargoes corrosion problem.

Because of the big changing temperature in a shipping container voyage. A changing temperature will lead to the humidity in a container go up and down throughout the voyage. If the temperature changes rapidly enough there are sure to be moisture risk, even if the container may be fairly dry.

Because warm air can hold more moisture than cold air. That means that if warm air is cooled, it become more humid. And if it is cooled enough, some of the moisture may rain out and condense. Such as container rain will directly drip down on the cargo’s outer package and cause damage, like peeling label, soften carton box, and lead to a big damage.

Product Comparison

TOPDRY Desiccant VS Traditionaly Desiccant

Traditional desiccant, like silica gel desiccant with only 10% moisture absorbent capacity of its own weight and 14 days absorption period. What's worse, the already absorbed moisture by silica gel desiccant will start to re-evaporate if the surrounding temperature rise over 40 degree centigrade, and that will cause a big moisture damage problem. And in a shipping container, it is very usual that the temperature inside a container will rise over 60 degree centigrade.

Due to the low moisture absorbent capacity and limited working temperature range of silica gel desiccant, we can declare that silica gel is not suitable for moisture absorbent in a shipping container.

If your cargo suffer from moisture damage, why not give TOPDRY Desiccant a chance to show you.
