Copeland Comfort Control (Alco) 037039 Cage Assembly

The Copeland Comfort Control (Alco) 037039 Cage Assembly (Model X22440B3B) is a critical metering component designed for T-Series take-apart thermal expansion valves, specifically the TCL and TCLE valve bodies. Engineered for versatile field service and capacity matching, this external equalizer cage allows technicians to precisely tune system performance across multiple refrigerants. It delivers a nominal capacity of 2 tons for R22 and R407C, 1-1/2 tons for R134a, and 1 ton for R12, R404A, R502, and R512. Its durable construction ensures stable superheat control and bi-flow capability, making it ideal for heat pump and commercial refrigeration applications. By utilizing this interchangeable cage, contractors can perform rapid repairs or capacity adjustments without removing the entire valve body from the line, significantly reducing downtime and brazing requirements. This assembly is rated for a maximum working pressure of 450 psig and requires a torque of 300 in-lb for secure flange mounting.

Key Benefits:

• Multi-Refrigerant Compatibility: Optimized for use with R22, R134a, R404A, and R407C, providing flexibility for various service calls.
• Serviceable Design: The take-apart construction allows for easy cleaning or replacement of the internal orifice without disturbing the piping.
• Precision Metering: Delivers consistent nominal capacity for accurate evaporator feeding and high-efficiency heat transfer.
• Operational Stability: Designed to maintain constant superheat even under fluctuating head pressures and varying load conditions.

Common Questions:

Which valve bodies are compatible with the X22440B3B cage?
This cage assembly is specifically designed for Alco T-Series take-apart valves, including TCL and TCLE models. It is not compatible with fixed-orifice or non-serviceable TXV series.

Does this cage support bi-flow operation?
Yes, when paired with the appropriate T-Series valve body, this cage assembly supports bi-flow capability, making it suitable for heat pump applications where refrigerant flow reverses during the heating cycle.

What is the difference between the "B" suffix and "A" suffix cages?
The B-suffix (like this X22440B3B) is designed for external equalizer setups, which are required for systems with significant pressure drops across the evaporator. An A-suffix cage is intended for internal equalizer configurations.
