Semi-hermetic, suction gas-cooled 4-cylinder reciprocating compressor in
compact design especially for the use with hydrocarbons. 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 INT69 G (for installation
in the switch cabinet) uses PTC sensors in series to monitor the winding
temperature and optionally the discharge gas temperature. The compressor has to
be equipped with heat protection thermostat and oil sump heater. The oil
filling is the special oil Synth 68. To ensure the safety measures, an
additional agreement has to be signed.

| 4) | 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.
