Description
The Ranco O12-1594 Dual Pressure Control is a sensing and switching component used to monitor both low and high pressure levels in refrigerant and air handling circuits. In HVAC systems it is applied in compressor protection and system regulation lines where it responds to pressure variations by activating or stopping electrical circuits to maintain safe operating conditions. It is typically installed on refrigeration piping with a 36-inch capillary tube for remote sensing placement. Rated for 10” WC and 100 PSI, it supports stable pressure monitoring and consistent operational pressure management setups in installed applications.
