Ranco A12-701 Control

The Ranco A12-701 Control is a versatile constant cut-in temperature control engineered for medium-temperature refrigeration systems requiring reliable off-cycle defrost. Designed with a SPST switch that closes on rise, this Robertshaw cold control ensures the evaporator is cleared of frost before initiating the next cooling cycle. It features a fixed 41°F cut-in and an adjustable cut-out range from 15°F to 31°F, providing high-precision regulation for reach-in coolers, vending machines, and beverage dispensers. The unit is equipped with a 84-inch vapor-filled capillary, offering ample length for flexible sensing bulb placement in various cabinet configurations. Built to withstand commercial demands, it includes laser-welded stainless steel bellows and high-amperage contacts rated for 16 FLA at 120/240 VAC. Professionals rely on the A12-701 as a universal refrigeration thermostat replacement for numerous OEM parts from True, Hobart, and Traulsen, streamlining service calls and maintaining consistent food-safe holding temperatures.

• Automatic Off-Cycle Defrost: The constant 41°F cut-in ensures the compressor stays off until the coil temperature rises sufficiently to melt accumulated frost.
• Extensive Compatibility: Serves as a direct high-performance replacement for many commercial brands, reducing the need for multiple stock items.
• Durable Construction: Heavy-duty stainless steel bellows provide long-term reliability against pneumatic stress and temperature fluctuations.
• Flexible Installation: Features 1/4-inch quick-connect terminals and a long 84-inch capillary for easy integration into tight equipment housings.

• Can the cut-in temperature be adjusted on this model? No, the A12-701 features a fixed 41°F constant cut-in. Adjustments to the dial only modify the cut-out (off) temperature.
• What systems is this control best suited for? It is ideal for medium-temp applications like reach-in refrigerators or drink coolers where frost management is necessary without dedicated defrost heaters.
• Does it include a mounting bracket? The A12 series typically features standard mounting configurations compatible with most commercial refrigeration brackets.
