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 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 INT69 G uses PTC sensors
in series to monitor the winding temperature and, if desired, the discharge gas
temperature.
