When the compressor is at a standstill, refrigerant diffuses into the lubricating oil of the compressors
housing, depending on pressure and ambient temperature. This reduces the lubricating capacity of
the oil. When the compressor starts up, the refrigerant contained in the oil evaporates out throught the
reduction in pressure. The consequences can be foaming and migration of the oil, causing oil shocks
under certain circumstances.
Operation:
The oil sump heater operates when the compressor is at a standstill. When the compres
-
sor starts up, the oil sump heater switches off again automatically.
Connection:
The oil sump heater must be connected via an auxiliary contact (or parallel wired auxili
-
ary contact) of the compressor contactor to a seperate electric circuit.
El. data: 230 V - 1 - 50/60 Hz, 160 W.
