Compressor mounted on a horizontal receiver. 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.
The large-volume electric terminal box (IP65) in solid aluminium design has a
fold-back and removable hinged lid with easy quick-release fastener. An
electronic motor protection MP10 with optical status indication uses PTC sensors
in series to monitor the winding temperature and, if desired, the discharge gas
temperature.
