Semi-hermetic suction gas-cooled reciprocating compressor in compact design. The best possible serviceability is provided by means of a replaceable drive motor, among other things. The compressor stands out due to its outstanding running comfort and efficient operating perbance. 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. An electronic motor protection uses PTC sensors in series to monitor the winding temperature and, if desired, the discharge gas temperature.

- The stated value for the max. power consumption is valid for the adjusted power supply.
- Starting current (rotor blocked):
-
Part winding (PW) motors: Winding 1 / Winding 1+2
-
Delta/Star (Δ/Y) motors: Δ / Y
- Take account of the max. operating current / max. power consumption for designing motor contractors, feed lines, fuses and motor protection switches. Motor contractors: Consumption category AC3.

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 bs 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.
