Copeland Comfort Control (Alco) 063127 Power Assembly

The Copeland Comfort Control (Alco) 063127 Power Assembly is a critical OEM replacement component engineered for high-precision superheat control in commercial refrigeration systems. This assembly, specifically model XC-726SW402B, is designed for use with R404A refrigerant and serves as the direct replacement for XC-726SW-2B. Built to handle low-temperature applications, it features an Application Temperature Range of -50°F to +10°F, making it a standard choice for walk-in freezers and industrial cooling racks. The inclusion of a 40 PSI Maximum Operating Pressure (MOP) charge is essential for protecting the compressor motor from overloading during high-load periods or after a defrost cycle. For installation flexibility, the unit comes with a 10-foot capillary tube and a 1/4" SAE flare equalizer connection. This Alco power assembly ensures the expansion valve responds accurately to evaporator pressure changes, maintaining optimal system efficiency and preventing liquid slugging.

• System Compatibility: Specifically calibrated for R404A systems, ensuring accurate thermostatic expansion valve (TXV) modulation.
• MOP Protection: The 40 PSI MOP prevents excessive suction pressure, shielding the compressor during heavy pull-down.
• OEM Fitment: Includes necessary capscrews for a direct-fit replacement, reducing downtime during field service calls.
• Extended Reach: The 10-foot capillary tube allows for versatile bulb placement on various evaporator coil configurations.
• Internal Component Reliability: Precision-welded stainless steel diaphragm provides consistent performance under extreme temperature fluctuations.

Is the 063127 compatible with other refrigerants?
This power assembly is specifically charged and calibrated for R404A. Using it with different refrigerants will result in incorrect superheat settings and potential system failure.

Does this replace the XC-726SW-2B?
Yes, the 063127 is the direct technical successor to the XC-726SW-2B model, maintaining the same physical and pressure specifications.

What is the purpose of the 1/4" SAE connection?
This is the external equalizer port which allows the power assembly to sense pressure at the evaporator outlet, compensating for pressure drops across the distributor and coil.
