The Ranco A30-182 is a professional-grade SPST cold control specifically engineered for commercial refrigeration temperature regulation. This constant differential temperature control features a 42-inch vapor-filled capillary sensing element, providing reliable mechanical switching for compressors in beverage coolers, horizontal freezers, and reach-in units. Built with laser-welded stainless steel bellows, it maintains a precise 17°F differential across a wide operating range (-6°F to 44°F). As a standard refrigeration thermostat replacement, the A30-182 includes a break-off shaft and mounting bracket for fast field installation. With a high-amperage rating of 20A at 120/240V AC, this Robertshaw appliance control handles heavy electrical loads without the need for additional contactors in most standard setups. Whether you are servicing ice machines or commercial vending equipment, the A30-182 delivers the consistent cycling required to protect inventory and maintain optimal evaporator temperatures. Key Benefits Precise Constant Differential: Maintains a fixed 17°F variance to prevent short-cycling and ensure stable thermal conditions. High Electrical Capacity: Rated for 20 Full Load Amps (FLA) at 120/240V, supporting high-torque compressor starts. Durable Capillary Design: The 42-inch stainless steel capillary offers flexible routing and superior corrosion resistance in high-moisture environments. Drop-in Compatibility: Readily adapts to most OEM configurations with included dial knobs and adaptable break-off shafts. Positive Off Position: Includes a dedicated "Off" setting for safe manual system shutdown during maintenance. Common Questions What are the specific temperature setpoints for the Ranco A30-182? The A30-182 is calibrated for a Cold Off of -6°F and a Warm On of 44°F, with a "Normal Off" at 3°F and a "Normal On" at 20°F. This makes it ideal for medium to low-temp commercial applications. Can the A30-182 replace other Ranco A30 series controls? Yes, the A30-182 is a highly adaptable replacement cold control for the A30, A22, and 9530 series, provided the capillary length and temperature range align with your specific cabinet requirements. Does this control require a bulb or is it a capillary-only sensor? This model uses a 42" capillary sensing element. For proper operation, ensure the capillary is in direct contact with the evaporator or placed within the recommended sensing well to accurately monitor the suction line or coil temperature.
