Ranco O10-1418 Temperature Control

The Ranco O10-1418 is a professional-grade medium temperature refrigeration control designed for precise regulation in walk-in coolers, reach-in units, and display cases. Featuring a 0°F to 55°F temperature range, this SPST (Single Pole Single Throw) switch is configured to close on rise, making it the industry standard for cycling motors, compressors, and solenoid valves. The unit utilizes a bulb coil sensing element, specifically an air coil design, which ensures high-accuracy air temperature monitoring without the need for an external capillary extension.

Built with a NEMA 1 enclosure and a non-conductive cover, this controller provides reliable performance in demanding commercial environments. Technicians can achieve exact calibration using the adjustable differential, which ranges from 3°F to 20°F. The laser-welded bellows offer enhanced durability against pressure fluctuations, while the heavy-duty plated steel frame and large, easy-to-read scale plate simplify field installations and setpoint adjustments. Rated for both 120V and 240V AC, the Ranco O10-1418 is a versatile solution for commercial refrigeration temperature control applications.

• Universal Compatibility: Designed for mid-temp applications including flower coolers, produce storage, and beverage dispensers.
• Precise Calibration: Features 7-revolution range adjustment screws for maximum setpoint accuracy.
• Robust Construction: Non-conductive cover and laser-welded bellows protect internal components from harsh mechanical Room conditions.
• Flexible Mounting: Compact design with a front-located captive cover screw allows for fast installation in tight electrical panels.
• High Electrical Capacity: Rated for up to 24 FLA at 120V, providing heavy-duty switching for large inductive loads.

What is the difference between a bulb coil and a standard capillary?
The bulb coil on the O10-1418 is a compact, coiled sensing element attached directly to the control body. It is specifically designed to sense ambient air temperature within the fixture, eliminating the need to route a long capillary tube to a remote location.

Can this be used for walk-in freezer applications?
No. The 0°F to 55°F range is optimized for medium-temperature refrigeration. For low-temperature freezer applications, a control with a lower range and appropriate defrost termination settings should be selected.

Does this unit support pilot duty?
Yes, the SPST switch is suitable for both line voltage motor control and pilot duty applications when used with a contactor or starter.
