Ranco O16-108 Pressure Control

The Ranco O16-108 Pressure Control is a heavy-duty single function high pressure control designed for demanding commercial refrigeration and air conditioning applications. Engineered for maximum flexibility, this SPDT pressure switch features a wide adjustable pressure range of 100 to 400 PSI and a 40 to 150 PSI differential, allowing for precise cut-out and cut-in settings. The Ranco O series is built with a rugged plated steel frame and laser-welded bellows to ensure long-term reliability even in high-vibration environments. This HVAC pressure controller includes the Super CAP capillary protection system, which reduces vibration stress on the 36-inch capillary tube, preventing common leak points at the brazed joints.

Key Benefits:

• Compatible with multiple refrigerants including R22, R12, and R502.
• Features automatic reset functionality for seamless system protection without manual intervention.
• Equipped with an SPDT switch (Single Pole Double Throw) for versatile wiring in pilot duty or direct motor control.
• Rugged NEMA 1 enclosure with a non-conductive cover and a high-visibility scale plate for fast, accurate field adjustments.
• Universal mounting design and 1/4 inch SAE flare nut connections streamline the installation process for technicians.

Common Questions:

• Can this control be used for low-pressure applications? No, the O16-108 is specifically a high pressure control. If you need suction-side monitoring, you should utilize the Ranco O16-107 or similar low-pressure models.
• Is it compatible with modern HFC refrigerants? While originally designed for R22 and R502, the mechanical bellows and materials are compatible with many non-corrosive refrigerants, provided the operating pressures fall within the 100-400 PSI range.
• How do I adjust the cut-in point? The cut-in point is determined by the cut-out setting minus the differential. Use the adjustable differential screw to fine-tune your system cycles and prevent short-cycling.
