6.3. Connection to a Pneumatic Conveying System (Optional)
Your drying facility works best in combination
with a pneumatic conveying system. In this
way, your drying hopper will always be supp-
lied with sufficient material.
The facility will only take as much material as
is required by the processing machines. The-
refore, the drying result will always be the
same.
Colortronic drying hoppers are equipped
with a suitable flange for adding a Colortronic
pneumatic conveyor.
Suction boxes with one or three suction tu-
bes can be supplied as well (optional). These
suction boxes are developped specifically for
this type of hopper.
The loading of the conveying line with materi-
al is adjusted by closing or by opening of the
control cover (A).
6.4. Return Air Cooler (Optional)
F
A return air cooler must be employed if the return air temperature is hig-
her than +65 °C (149 °F).
A return air cooler improves the efficiency of the drying cells.
&
The lower the return air temperature, the better the efficiency of the dry-
ing cells.
The return air cooler can be connected to a coolant circuit or to the water mains network.
