Two semi-hermetic compressors mounted rigidly next to one another on base
frames and lined with a common suction line connection on the suction side. The
basic compressor:
Semi-hermetic, suction gas-cooled 4-cylinder
reciprocating compressor in compact design. The best possible serviceability is
provided by means of a replaceable drive unit, 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 optional oil sump heating is carried out using an immersion sleeve and can
therefore be replaced without intervening in the refrigeration cycle.
An additional connection facility for an oil level regulator is available as
a standard. The electrical connection is simplified by means of a large-volume
electric terminal box. 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.
