See capacity table for desiccant dryers concerning recommended drying times, or ask the supplier
of the appropriate raw material.
For drying temperatures above 140° or below 60°C only HT/LT versions can be used.
The above capacity table states recommended values only, based on the drying of the specific
materials down to a residual moisture content of 0.02% which, however, will vary depending on the
type of material.
The capacities are based on a general bulk density of 0.6 with the exception of PE and PETG to
which a bulk density of 0.55 and 0.85 respectively forms basis.
The original moisture content in the material and any additives can prolong the drying time and
hence reduce the specified capacities.
3.5 Safety measures
The alarms fitted on the DFD dryer activate a code. The alarm can be connected to a yellow
flashing light on the DFD dryer.
