We regularly test our desiccants to ensure performance under realistic and extreme conditions. One requirement from the German Armed Forces, where our SeaDry container desiccants are listed, was that they must function reliably even after exposure to very low temperatures.
To verify this, a two-stage test was carried out:
- Test step 1: 24 hours at -40°C in a cold chamber at BFSV Verpackungsinstitut Hamburg GmbH
- Test step 2: 25 days at 37°C and 90% relative humidity in a climate chamber at ThoMar OHG
At -40°C, virtually no moisture absorption takes place because the air contains almost no moisture under these conditions. This phase therefore primarily served as a stress test to ensure that the desiccant remains fully operational after extreme cold.
Result: As the test chart shows, the performance of the container desiccant is not impaired by the extreme cold. Afterwards, the desiccant bag once again reached peak moisture absorption values.
With the Germany-made SeaDry container desiccants in ISO 9001-certified quality, you can reliably protect your goods from moisture damage during transport and storage—even in cold regions or during longer standstill times in winter.
