Technical description
8.4

Refrigerating compressor

The employed refrigerating compressors are constructed by leading manufacturers. The hermetically sealed
construction is absolutely gastight. The integrated safeguard protects the compressor against overheating and excess
current. The protection is automatically reset as soon as the nominal conditions are reached again.
8.5

Condenser

The condenser is the component in which the gas coming from the compressor is cooled down, condensed and
liquefied. Under no circumstances must the temperature of the ambient air exceed the nominal values. It is also
important that the condenser unit is kept free from dust and other impurities.
8.6

Filter dryer

Despite controlled vacuuming, traces of moisture can accumulate in the refrigeration cycle. The filter dryer serves to
absorb this moisture and to bond it.
8.7

Capillary tube

The capillary tube is a copper tube with a reduced diameter which is located between the condenser and the
evaporator, serving as a restrictor to reduce the pressure of the refrigerant. The pressure reduction serves to reach an
optimum temperature inside of the evaporator. The lower the outlet pressure at the capillary tube, the lower the
evaporation temperature.
The length and the inner diameter of the capillary tube are exactly dimensioned to ensure the performance of the
dryer. Settings or maintenance works are not required.
8.8

Aluminium heat exchanger

The heat exchanger module consists of an air/air heat exchanger, an air/refrigerant heat exchanger, and of a high-
performance separator. The compressed air flows top-down through the heat exchanger. The large cross-sections of
the flow passages cause low flow rates and low compressed-air losses. In the air/air heat exchanger, the heat
exchange is effected in a reverse current. This guarantees maximum heat transfer. The heat transfer in the
air/refrigerant heat exchanger also takes place in a reverse current. This allows full evaporation of the refrigerant. The
high-performance separator ensures almost complete separation of the condensate. Maintenance of the high-
performance separator is not required.
