Copeland Comfort Control (Alco) 059189 Power Assembly

The Copeland Comfort Control (Alco) 059189 Power Assembly, specifically the XB-1019SC-1B model, is a high-performance replacement component for T-Series take-apart expansion valves. Engineered for R404A refrigerant systems, this power element features a 1/4" SAE flare equalizer and a 5-foot capillary tube, providing the necessary reach and flexibility for remote bulb placement on the suction line. This assembly is designed for medium-to-low temperature applications, maintaining a precise application temperature range of -20°F to +50°F. By utilizing a stainless steel construction, it ensures durability against the corrosive effects of moisture and environmental contaminants common in commercial refrigeration racks.

For technicians performing field service, the XB-1019SC-1B power head offers a modular solution, allowing for the replacement of the power element without disconnecting the valve body from the refrigerant lines. This facilitates rapid repairs on TCLE, TJLE, and TJRE series valves while maintaining system integrity. The inclusion of new capscrews ensures a secure, leak-proof seal during the reassembly of the valve head. This part is essential for restoring accurate superheat control and preventing liquid floodback, effectively protecting the compressor and optimizing the evaporator's heat transfer efficiency.

• Compatible with R404A and R507 refrigerants in medium and low-temp refrigeration.
• Take-apart design allows for simplified component replacement and reduced downtime.
• Externally equalized 1/4" SAE connection compensates for evaporator pressure drop.
• Durable 5-foot capillary tube supports optimal bulb positioning for sensitive thermal response.
• Includes required mounting hardware for immediate field installation.

• Does this power assembly work with internal equalizer valves? No, the XB-1019SC-1B is designed specifically for externally equalized T-series valve bodies.
• What happens if the capillary tube is kinked? A kinked capillary tube will restrict the charge movement, leading to an unresponsive expansion valve and potential evaporator starving.
• Is this compatible with R134a? While the body may fit, the 059189 power assembly is charged specifically for R404A pressure-temperature curves and should not be used with R134a.
