The desiccant is already disassembled and immediately available.
The desiccant was sucked out of the container with a vacuum cleaner and packed separately in airtight bags.
The desiccant is still in a usable condition. It is not oily or soiled.
There is the possibility of external re-drying.

The TÜV has inspected the inside of the containers and an expert opinion is currently being prepared.
