Absortop shipping desiccant

Absortop shipping desiccants protect cargo and cargo packaging from moisture damage during sea transportation. Absortop is the latest desiccant in the Absortech product family and is uniquely designed for bulk cargo transportation. Absortop is based on the proven ability of calcium chloride to aggressively remove moisture from the air.

Absortop is specifically designed for use in bulk containers and fully loaded containers. Absortop is mounted on the container ceiling; it is tightly secured, robust and will stay in place even when the container is tilted. The absorbed water cannot re-evaporate into the container since it is transferred and stored in the lower compartment of the absorber.

Generally, 2-3 absorbers are required for 20-foot containers and 4-6 absorbers for 40-foot containers. However, the number may vary depending on the length of the voyage, the range of temperatures encountered and the type of products being protected.
