MP-MP-A Oil Differential Pressure Controller
Differential oil pressure controllers MP 54 and MP 55 are safety switches used to prevent low oil pressure in refrigeration compressors. If the oil pressure drops below the set value, after a certain time interval, the oil pressure differential controller will act to stop the compressor.
