Refrigeration Unit; Heater Battery; Thermal Sensor After Cooler; Safety Temperature Limiter - BÖWE M12 Instruction Manual

7. Functional Units

7.12.1 Refrigeration Unit:

Refrigeration technology is used to cool the air cooler in the airshaft and to cool 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.

7.12.2 Heater Battery:

The drying air is heated up in the heater battery. The heater battery is fed either by external steam or
by the small electric steam generator that is integrated in the machine.

7.12.3 Thermal Sensor After Cooler:

A thermal sensor regulates the aftercooler temperature.

7.12.4 Safety Temperature Limiter:

In addition, an independent safety temperature limiter is built in after the cooler, in order to monitor
the function of the cooler. It is set to a maximum temperature. When the temperature reaches this
level, the machine switches off.
