Semi-hermetic suction gas-cooled 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.
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 an oil sump heater (accessory).
