Johnson Controls P45NCA-106C

LUBE OIL CONTROL

W/TIME DELAY; FIXED SETTINGS 12 PSI SETPOINT; 36” CAP W/STYLE 13

The series P45 controls are designed to give protection against low lube-oil pressure on pressure lubricated refrigeration compressors. The controls measure the pressure differential (net oil pressure) between the pressure generated by the oil pump and the refrigerant pressure at the crankcase. A built-in time delay switch allows pressure build-up during start and avoids nuisance shut-down on pressure drops of short duration during the running cycle.
