Ranco O60-200 Temperature Control

The Ranco O60-200 is a rugged, wide-range temperature control designed for heavy-duty commercial refrigeration and HVAC industrial applications. Featuring an Open High/Low configuration, this SPDT thermostat operates within a precision range of 95° to 240°F, making it an ideal choice for walk-in units, display cases, and industrial heating processes. The 96-inch capillary tube provides extensive reach for remote sensing, while the 3/8" x 6" cross-ambient bulb remains virtually unaffected by ambient temperature fluctuations, ensuring consistent cut-in and cut-out accuracy.

Built with a heavy-duty plated steel frame and a NEMA 1 non-conductive cover, the Ranco O60-200 utilizes a laser-welded bellows system and gas-filled sensing element for ten times the sensitivity of standard wide-range controls. Contractors will appreciate the seven-revolution range adjustment screws and the raised screw terminals that simplify wiring in the field. This flexible temperature control offers an adjustable differential from 6° to 50°F, allowing for exact system tuning and equipment protection against extreme temperature cycling.

• Precision Sensitivity: The O60 series provides 10x the setting sensitivity of competing wide-range controls for tighter thermal regulation.
• Versatile Mounting: Compact NEMA 1 enclosure with universal mounting brackets allows for seamless replacement of narrower OEM controls.
• Reliable Sensing: The 96-inch capillary and gas-filled bulb are non-position sensitive, providing flexibility in disparate refrigeration equipment layouts.
• Industrial Durability: Laser-welded bellows and robust frame construction withstand the rigors of high-temperature industrial environments.

Is the Ranco O60-200 suitable for both heating and cooling?
Yes, the Single Pole Double Throw (SPDT) switch configuration allows the control to be wired to open or close a circuit on temperature rise, supporting versatile application requirements.

What is the accuracy of the adjustment screws?
One full turn of the range adjustment screw equals approximately 7.5°F, while one turn of the differential screw equals approximately 9°F, facilitating highly precise setpoints.

Can this control replace a Honeywell or Johnson Controls model?
The Ranco O60-200 is an industry-standard universal replacement for several high-temperature controls, including the Honeywell L4008/L6008 series and Johnson Controls A19 series.
