Compressor mounted on a horizontal receiver. 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.
