Description of Compressor Parts Crankcase Heater


Working environment temperature of designed air-conditioner compressor is about 4℃ while surround environment temperature is bellow zero.Air-conditioner is hard to make heater is necessarily used at end of central air-conditioner to make the supplementary heat.Our subsidiary electric heater series are the most suitable and ideal heating source designed and manufactured for this application.Moreover,our subsidiary heater series do not need any other subsidiary equipment.They have such many obvious advantages as being easy in installing,safe in operating and PTCelectric heating element.


Function and Introduction of Air-conditioning Compressor Crankcase Heater


1.When the air-conditioner is used under severe cold condition,drive engine oil inside can condense,and affect the normal starting of the unit.The heating belt can promote to thermalize engine oil,and help the unit to be started normally.

2.It can protect compressor from being damaged in starting in cold winter,and prolongs the service life.(In cold winter,engine oil condenses,hard friction can generate in starting,and may cause damages of the compressor.)
