Robertshaw P32-1201

TEMPERATURE CONTROL CHILLER, LOW PRESSURE CO

Type P32 Low Pressure Limit Control

The Ranco® P32 low pressure control provides freeze protection for low refrigerant protection on chillers and other refrigeration systems by sensing suction pressure. It is suitable for R12, R22 and R502 refrigerants. A time delay is provided to allow for startup in low ambient and momentary low pressure conditions during the run period. The timer is of the heated bimetal (warp) switch design with an ambient temperature compensator. Once the time delay period (standard is 120 seconds) has elapsed, the manual reset button must be depressed to restart the compressor. A five minute cool-down period is required before resetting.
