RANCO Single Pressure Controls

Designed for use with HVAC compressors to avoid loss of refrigerant. Feature a DPST / SPST / SPDT switch and can control pressures ranging from 0 to 450 psi

Ranco O Series pressure controls are suitable for protecting compressors from losing refrigerants or from excessive system pressure, which may further damage the condenser fans in the HVAC systems. These single-pressure controls have a heavy-duty plated steel frame with a non-conductive plastic cover for added strength. They feature a compact design for use in tight spaces, an auto reset button on manual controls for quick setting and easy-to-read low- / high-pressure scale plates. They also come integrated with laser welded bellows for an extended life service and screw terminals for easy wiring connection. Choose from an array of these pressure controls available in 5 to 35, 10 to 40 and 40 to 150 psi differential pressure options.
