All the components of the refrigeration cycle have been designed for heavy-duty operation.


The heat contained in the air within the cabin is directly exchanged and cooled down; the evaporator is equipped with a filter which can be cleaned and/or replaced several times. As the air is cooled down the condensation water wich is generally generated on the evaporator is to be drained.

The evaporator unit is connected with a compressor-condenser unit, wich comes into contact with the dust loaded ambient air and consequently with the high ambient temperature. These two functional modules have either been assembled in our works to form a so-called compact unit, or they have to be connected through the refrigerant carryng tubes on site to form a split-type unit.
