Ranco A30-184 Refrigerant Control

The Ranco A30-184 is a professional-grade constant cut-in temperature control engineered for precision in commercial refrigeration systems, ice machines, and beverage coolers. This SPST cold control features a 19°F fixed differential and a wide temperature range of -7°F to 40°F, ensuring stable performance across diverse cooling applications. Built with a laser-welded stainless steel bellows and a 42-inch capillary tube, the A30-184 provides the mechanical durability and installation flexibility required for high-cycle environments. Rated for 20 Amps at 240V AC, this refrigerant control includes standard 1/4-inch quick-connect terminals and a break-off shaft for easy field adaptation. Whether you are performing a Ranco A10-667 replacement or a custom install, this unit delivers reliable pneumatic action with a vapor-filled sensing element to maintain critical setpoints. Designed for HVACR contractors, the A30-184 is the industry standard for commercial refrigerator thermostats and ice machine temperature regulation.

• Broad Compatibility: An adaptable design allows for seamless replacement of various OEM controls in vending machines, coolers, and freezers.
• Robust Electrical Rating: Features high-amperage contacts suitable for 120V or 240V AC motor loads.
• Precision Engineering: The constant cut-in mechanism ensures consistent system start-up temperatures, preventing short-cycling.
• Durable Construction: The stainless steel bellows resist fatigue and environmental wear for long-term field reliability.
• Easy Installation: Includes break-off shafts and 42" capillary for flexible mounting in tight appliance cabinets.

What are the specific temperature settings for the Ranco A30-184?
The A30-184 is configured with a normal off at 6°F and a normal on at 25°F. Its full range extends from a cold-off setting of -7°F to a warm-on setting of 40°F, providing a fixed 19°F differential.

Can this unit replace a Ranco A10-667 control?
Yes, the Ranco A30-184 is a frequently recommended cross-reference for the A10-667, offering comparable SPST switching and capillary length for commercial refrigeration duty.

Is the capillary tube length sufficient for reach-in coolers?
The 42-inch capillary provides ample reach for most reach-in coolers, ice machines, and beverage dispensers, allowing for remote sensing away from the main control housing.
