  Compressor assembly

When the compressor is at a standstill, refrigerant diffuses into the lubrication oil of the compressor 
housing, depending on pressure and ambient temperature. This reduces the lubrication capacity of 
the oil. When the compressor starts up, the refrigerant contained in the oil evaporates out through 
the reduction in pressure. The consepuences can be lack of lubrication, foaming and migration of the 
oil, which can eventually lead to compressor damage.
To prevent this, the oil can be heated via an oil sump heater. 

Operation:       

  Oil sump heater ON at standstill of the compressor.  

Oil sump heater OFF during operation of the compressor

Connection:

      Oil sump heater must be connected via an auxiliary contact (or parallel wired 

auxiliary contact) of the motor contactor to a separate electric circuit

.

4.10  Oil sump heating

WARNING!  

The oil sump heater must not be connected to the electrical circuit 
of the safety control chain !

Oil sump heater: 230 V – 1 – 50/60Hz, IP65
