Ranco O10-1433 Temperature Control

The Ranco O10-1433 Low Temperature Control is a heavy-duty SPST refrigeration thermostat engineered for precise thermal regulation in commercial freezers, walk-in coolers, and refrigeration display cases. Built with a laser-welded bellows for enhanced mechanical longevity, this control operates across a wide temperature range of -35°F to 15°F. It features an open-on-drop (close-on-rise) switch action, making it an ideal choice for compressor cycling and freezer temperature management where reliability is a priority.

For ease of installation in tight mechanical spaces, the Ranco O10-1433 includes a 72-inch capillary tube with a standard 3/8-inch remote bulb for flexible sensing placement. The unit is housed in a NEMA 1 enclosure with a non-conductive cover and front-located captive screws to streamline field service. With a 7-revolution range adjustment screw and an adjustable differential of 3°F to 20°F, technicians can dial in exact setpoints to prevent short-cycling and maintain consistent product integrity.

• Precise Range Control: Designed specifically for low-temp applications from -35°F to 15°F.
• Robust Construction: Features laser-welded bellows and a plated steel frame for high-cycle environments.
• Universal Compatibility: Compact design allows for direct mounting or bracket-assisted installation in diverse refrigeration equipment.
• Field-Serviceable: Large, easy-to-read scale plates and raised screw terminals simplify wiring and onsite adjustments.
• High Load Capacity: Rated for up to 24A at 120/240V AC, suitable for direct compressor control or pilot duty.

Is this control suitable for walk-in freezers?
Yes, its low-end range of -35°F is purpose-built for commercial freezer applications requiring automatic reset cycling.

What is the switch action for the O10-1433?
This is an SPST control that opens the circuit on temperature drop and closes on temperature rise.

Can I use this for air-sensing or coil-sensing?
While it is primarily used with the remote bulb for medium/low-temp fixtures, the 72-inch capillary provides the reach needed for various sensing configurations.
