BITZER semi Hermetic AC compressor R227ea electrical rewinding and mechanical side repairing After testing The Bitzer Ecoline semi-hermetic compressors provide a broad range covering HFC & HCFC refrigerants meeting the demanding requirements of modern ..This is the Lodam SEB1 (signal evaluation basic) used on Bitzer semi-hermetic compressor. Here we have created a simulation rig to show how it detects motor overheating. The compressor uses embedded PTC thermistors in the stator. With up to 9 in series , anyone can create an overload condition using a series looped total resistance signature R1+R2+R3 etc until the trigger resistance (equivalent temperature) is reached. The simulation unit uses a 10K ohm variable resistor to represent an overheating compressor. These devices are so very important, and save many Refrigerant R227ea..HVAC
