Maneurop Refrigeration Hermetic Reciprocating Compressor MTZ144HV4AVE

Product description:

A crankcase heater protects against the offcycle migration of refrigerant and proves effective if oil temperature is maintained 18oF above the saturated LP temperature of the refrigerant. Tests must thereby be conducted to ensure that the appropriate oil temperature
is maintained under all ambient conditions. A PTC crankcase heater is recommended on all stand-alone compressors and split systems.
PTC crankcase heaters are self-regulating. Under extreme conditions, such as very low ambient temperature, a belt type crankcase heater could be used in addition to the PTC heater; although this is not a preferred solution for 1 and 2 cylinder compressors. The belt crankcase heater must be positioned on the compressor shell as close as possible to the oil sump to ensure good heat transfer to the oil.
Belt crankcase heaters are not self-regulating. Control must be applied to energize the belt heater once the compressor has been stopped and then to de-energize it while the compressor is running. The belt heater must be energized 12 hours before restarting the compressor following an extended down period.
If the crankcase heater is not able to maintain the oil temperature at 18oF above the saturated LP temperature of the refrigerant during off cycles or if repetitive floodback is present a the Liquid Line Solenoid Valve (LLSV) +
pump-down cycle is required, eventually in conjunction with a suction accumulator.
