Robertshaw O12-1502 Refrigeration Pressure Controller

The Robertshaw O12-1502 Refrigeration Pressure Controller is a versatile, adjustable dual-pressure control designed for commercial refrigeration systems. With an operating pressure range from 12 Inch Mercury Vacuum to 50 PSI (Open Low) and 150 to 450 PSI (Open High), it covers both evaporator and condenser applications. The adjustable differential ranges from 5 to 35 PSI, enabling precise cycling and energy efficiency, while the SPST contact configuration delivers reliable electrical switching for robust control. A 1/4 inch SAE flare nut connection and a 36 inch capillary tube simplify installation in tight spaces, and the auto reset feature ensures continuous operation after a fault.
