Description
The Ranco oil differential pressure controls/switches are for use with all refrigeration compressors using external oil pumps with refrigerants. It protects the compressor against loss of lubricating oil pressure, which could otherwise cause severe bearing damage resulting in a compressor breakdown. Connected to the crankcase and oil pump by capillaries, the pressure switch senses the difference between the pressure in the crankcase and that of the outlet side of the oil pump. Feature: time delay to avoid nuisance shutdown, choice of safety timings, and more.
