Operating instructions

3.1. General information
The dehumidified air dryer CTT 30
has been developed for the drying
of plastic granules. Because of its
compact construction it can be in-
stalled directly beside the process-
ing machine (with the drying hopper
on the processing machine) or with
a drying hopper as a mobile attach-
ment (compact unit).
The dryer works on the principle of
dehumidified air, i.e. the air is not
only heated but also dehumidified
before flowing into the drying hop-
per.
This principle allows plastic gran-
ules to be dried to a very low residual moisture content.
The drying temperature is adjustable. If need be, the dehumidified air can be
heated to a maximum temperature of 180 °C (upper limit). Because of the heat re-
leased when the water is absorbed in the drying cells the lower limit value of the
dehumidified air temperature is approximately 70 °C.
The drying process is continuous, i.e. there are no rest periods as a result of the
regeneration of the drying agent.
F
The dryer is designed for continuous operation.
The dryer must only be started up if the drying hopper is full.
All operations are fully automatic.
