Two-stage semi-hermetic suction gas-cooled 6-cylinder reciprocating compressor in compact design for expanded use in low temperature application (stages divided into: LP/HP 2:1). The intermediate pressure line is mounted and insulated. Liquid sub cooler, expansion valve, two sight glasses and filter dryer are enclosed separately for individual external mounting. As an option it is possible to have these mentioned units attached directly to the compressor (lined and insulated). This cost-effective system is precisely tuned to the refrigerant. 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. 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 (IP54) in solid metal design has a fold-back and removable hinged lid with easy quick-release fasteners. The optional oil sump heating is carried out using an immersion sleeve and can therefore be replaced without intervening in the refrigeration cycle. A direct connection facility for an oil level regulator is possible on one of the three standard sight glasses. The electronic motor protection MP10 with optical status indication uses PTC sensors in series to monitor the winding temperature and the discharge gas temperature at the HP stage. The oil pressure safety switch is completely mounted. A standard oil service valve simplifies oil changes.
