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.
