Air-cooled condensation unit with large-dimensioned condensers, optimised
closed loops and heat transfer in conjunction with high-power fans. These
cost-effective fans with thermal protection shield are well-suited for
electronic speed regulation for an optimal condensation pressure
setting.
Semi-hermetic suction gas-cooled reciprocating compressor in
compact design. The best possible serviceability is provided by means of a
replaceable drive motor, among other things. The compressor stands out due to
its outstanding running comfort and efficient operating performance. The suction
shut-off valve can be rotated by 90° in each instance. Dependable mechanism
lubrication is guaranteed by means of an oil pump which is independent of
rotating direction, as well as a large-volume oil sump. An electronic motor
protection uses PTC sensors in series to monitor the winding temperature and, if
desired, the discharge gas temperature.
