Ranco A30-2210 Refrigeration Control

The Ranco A30-2210 is a high-performance constant differential refrigeration control engineered for medium-temperature applications, including beverage coolers, reach-in refrigerators, and vending machines. This SPST cold control features a 48-inch vapor-filled capillary tube for accurate remote temperature sensing. With a dedicated "Off" position on the dial, it allows for easy system servicing and manual shutdown. The unit operates on a fixed 8°F differential, ensuring stable compressor cycles and preventing short-cycling in commercial environments. Rated for 20 FLA at 120/240V, the Ranco A30-2210 refrigeration control utilizes laser-welded stainless steel bellows for long-term setpoint stability. It serves as a direct functional replacement for many OEM parts from beverage-air and Hobart. Designed for rapid field installation, it includes a break-off shaft and standard 1/4 inch quick-connect terminals, making it an essential HVACR replacement part for technicians maintaining commercial refrigeration systems.

Key Benefits:

• Constant Differential Performance: Maintains a steady 8°F variance between cut-in and cut-out to protect compressor life.
• Vapor-Filled Sensing: The 48" capillary provides responsive pneumatic action across a 32°F to 61°F temperature range.
• High Amperage Capacity: Heavy-duty contacts rated up to 20 Amps handle demanding commercial evaporator fan and compressor loads.
• Universal Adaptability: Includes mounting brackets and a flatted/slotted break-off shaft to fit various cabinet depths and dial configurations.

Common Questions:

• What is the switch action for the A30-2210? This is an SPST switch that closes on temperature rise (cut-in) to activate the cooling cycle.
• Can this replace a constant cut-in control? No, this is a constant differential control. For applications requiring a fixed cut-in regardless of the dial setting, a Ranco A12 series should be used.
• What are the specific temperature setpoints? Under normal settings, the unit has a "Normal Off" of 32°F and a "Normal On" of 40°F, with a "Warm On" peak of 42°F.
