Ranco A30-185 Refrigerant Control

The Ranco A30-185 Refrigerant Control is a heavy-duty single pole single throw (SPST) temperature control engineered for precision in commercial refrigeration service. This constant cut-in control features a 42-inch capillary tube, providing necessary reach for flexible mounting in various evaporator configurations. Designed with a wide temperature range and adjustable differential, the A30-185 is a reliable solution for refrigeration pressure switch applications where maintaining load integrity is critical. Its thermal-actuated bellows system reacts to temperature fluctuations with high repeatability, ensuring consistent cycle times and preventing evaporator freeze-up. Technical professionals prefer this Ranco cold control for its rugged construction and broad compatibility across food service and cold storage platforms. Whether performing a HVAC compressor control replacement or upgrading a legacy system, this mechanical temperature controller provides the durability required for high-cycle industrial environments without the failure rates associated with complex electronic alternatives.

• Universal Compatibility: Engineered as a versatile HVAC replacement part suitable for a wide array of reach-in coolers and commercial refrigeration units.
• Precise Thermal Response: The 42" capillary allows for accurate remote sensing, ensuring the SPST switch cycles efficiently based on real-time evaporator temperature.
• Durable Construction: Built to withstand the vibration and environmental stressors common in refrigeration maintenance and industrial service.
• Adjustable Range: Allows technicians to fine-tune the cut-out and cut-in points to meet specific equipment load requirements.

What are the electrical ratings for this control?
The Ranco A30-185 is rated for standard inductive loads typically found in commercial refrigeration compressors, generally handling up to 20 full load amps at 120V/240V AC.

Can this be used as a replacement for other A30 series controls?
Yes, provided the capillary length and temperature range align with the original equipment manufacturer (OEM) specifications for the specific cabinet or cooler being serviced.

Is the capillary tube bendable for tight installations?
The copper capillary is pliable, but technicians should use a tubing bender or careful hand-molding to avoid kinking, which would restrict the refrigerant charge and cause control failure.
