11.2 Functional description
Operating principle – All dryer models described in this manual function according to the same principle. The hot and
moisture-loaded air is led into an air/air heat exchanger. Afterwards, the air flows through an evaporator, which is also
known as an air/refrigerant heat exchanger. The air temperature is reduced to approximately 36°F (2°C), so that water
vapour condenses to liquid. The continuously accumulating condensate is collected in the separator to be discharged
via the condensate drain. Subsequently, the cold and dry air is led through the air/air heat exchanger, so that it is
reheated to up to 46°F (8°C) below the inlet temperature when leaving the dryer.
Refrigeration cycle – The refrigerant is conducted through the compressor and reaches a condenser under high
pressure. There, cooling-down takes place, making the refrigerant condense to a liquid state which is under high
