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.

| 5) | Declared dual-number noise emission values are in
accordance with ISO 4871. The corresponding uncertainty to the sound power level
is KWA = 2,5 dB and to the sound pressure level is KpA =
2,5 dB. The values are valid for 50 Hz with the refrigerant R404A at the
standard rating points according to EN 12900.
- A-weighted sound power level LWA (re 1 pW), in decibel. To
determine the values, measurement methods of the ISO 3740 standard with
accuracy class 2 or higher were used .
- A-weighted sound pressure level LpA (re 20 µPa), in decibel.
The values are calculated from the sound power level in accordance with ISO
11203: LpA = LWA - Q2 at a distance of d = 1m
to the reference box.
