Semi-hermetic, suction gas-cooled 8-cylinder 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
cover can be rotated by 90° in each instance. Dependable mechanism lubrication
is guaranteed by means of a double-circuit lubrication system using an oil pump
which is independent of rotating direction, as well as a large-volume oil sump.
The standard oil sump heating is carried out using an immersion sleeve and can
therefore be replaced without intervening in the refrigeration cycle. A direct
connection facility for an oil level regulator is possible on one of the three
standard sight glasses. The large-volume electric terminal box in solid metal
design has easy quick-release fasteners. The 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.
