aUnless noted otherwise, all tests are run at 23°C (73°F) and 50% relative humidity.
bUnless noted otherwise, the test method is ASTM.
cUnits are in SI or US customary units.
dBased on a 35 kg (78 lb) hopper desiccant dryer. Larger hoppers may require lower temperatures to avoid sticking.
eBased on a 76°C drying temperature and starting moisture level of 5400 ppm or 0.54% with average ambient conditions of 8.3°C (47°F) and 60% RH. Higher starting moisture levels, lower drying temperatures, and/or higher humidity and higher temperature ambient conditions will require longer drying times to reach moisture levels below 300 ppm or 0.03% as recommended.
