ABSTRACT:
A circulation cooler (10) has a heat exchanger (12) in a housing (11) that contains a cooling liquid and is detachably connected by its forward flow (13) to an inlet line (5), and by its return line (14) to the outlet (6) of a condenser (4) of a distillation apparatus (1). The circulation cooler (10) moreover has a vacuum pump (21) inside its housing (11) and an absorber (28) outside its housing (11). A second condenser (24) is interposed along the cooling agent inlet line (13) between the circulation cooler (10) and the condenser (4) of the distillation apparatus (1), and is connected to a vacuum line (27). The cooling liquid (25) flows successively to the heat exchanger ( 12) through the two condensers (24, 4) , then back to the heat exchanger (12). In both condensers, which are under a vacuum through common vacuum line (26, 27) , the condensation of the liquid substances is effected in the form of main condensation and aftercondensation phases. Any aerosols which still pass through the vacuum pump (21) are captured by the absorber (28).
