Two semi-hermetic compressors mounted rigidly next to one another on base
frames and lined with a common suction line connection on the suction side. The
basic compressor:
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 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 large-volume
electric terminal box (IP66) in solid aluminium design has a fold-back and
removable hinged lid with easy quick-release fastener. An 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.
