7.11.1. Refrigeration Unit:
Refrigeration technology is used to cool the air cooler in the airshaft and, in special cases
(optional equipment), for cooling the solvent. The low aftercooler temperature of the air cooler
reduces the solvent residue concentration in the cage and the solvent emissions.
The heated gas that arises in the cooling compressor (heat pump principle) is fed through the
pre-heater. The energy consumed for drying is considerably reduced because the thermal
energy is fed back.
The air cooler is specially coated as protection against corrosion.
7.11.2. Heater Battery:
The drying air is heated up in the heater battery. The heater battery is either steam- or electrical
heated.
7.11.3. Thermal Sensor After Cooler:
A thermal sensor regulates the aftercooler temperature.
