Ranco A30-2211 Refrigeration Control

The Ranco A30-2211 Refrigeration Control is a heavy-duty constant differential temperature control engineered for critical cooling performance in commercial refrigerators, freezers, and ice machines. Featuring a 48-inch vapor-filled capillary tube and SPST switching, this control maintains a consistent 10-degree differential to ensure precise compressor cycling. The laser-welded stainless steel bellows provide long-term reliability against pressure fluctuations, while the high-amperage contacts (20 Amps at 240V AC) handle the heavy electrical loads of industrial components without premature pitting. This model includes a break-off shaft and mounting bracket for fast field replacement of older OEM controls. Whether you are servicing a beverage cooler or a walk-in freezer, the Ranco A30-2211 offers a dependable normal-off range of 0°F to 10°F, making it a standard choice for technicians who require mechanical temperature controls that stand up to rigorous environmental demands. Its compact design and pneumatic action deliver consistent switching for optimized system efficiency.

• Precise Cycling: Features a fixed 10°F constant differential to prevent short-cycling and maintain stable case temperatures.
• Industrial Durability: Equipped with laser-welded stainless steel bellows for increased resistance to fatigue and vibration.
