Semi-hermetic, suction gas-cooled 8-cylinder reciprocating compressor in compact design especially for the use with hydrocarbons. 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 cover can be rotated by 90° in each instance. Dependable mechanism lubrication is guaranteed by means of a double-circuit lubrication system using 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.

A direct connection facility for an oil level regulator is possible on one of the three standard sight glasses. The large-volume electric terminal box in solid metal design has easy quick-release fasteners. The electronic motor protection MP10 (for installation in the switch cabinet) with optical status indication uses PTC sensors in series to monitor the winding temperature andthe discharge gas temperature. The compressor has to be equipped with heat protection thermostat and oil sump heater (accessory). The oil filling is the special oil Synth 68.  To ensure the safety measures, an additional agreement has to be signed.
