Description
The Copeland 062722 (Model TRAE+ 15 HCA 10FT 7/8 X 1 1/8 ODF S/T) is a heavy-duty, externally equalized thermal expansion valve engineered for high-capacity heat pump refrigeration systems. Designed to deliver precise refrigerant metering at 15-ton capacity, this straight-body TXV is a trusted choice for commercial HVAC and refrigeration contractors working with R22 or R407C refrigerant systems.
Key Features
- Capacity: 15 Ton — suitable for large commercial heat pump applications
- Compatible Refrigerants: R22 and R407C
- Connection Type: Sweat (ODF) — 7/8″ inlet x 1-1/8″ outlet
- Body Style: Straight body for straightforward inline installation
- Capillary Tube: 10-foot capillary tube for flexible bulb placement and remote sensing
- Equalization: Externally equalized for accurate superheat control across longer evaporator circuits
- Charge Type: Heat pump charge — optimized for bidirectional flow in heat pump operation
Why External Equalization Matters
Externally equalized TXVs reference downstream evaporator pressure directly at the outlet, rather than the inlet. This design compensates for pressure drop across the evaporator coil, resulting in more accurate superheat control and improved system efficiency — especially critical in large-tonnage or multi-circuit evaporator applications.
Heat Pump Charge
The heat pump charge on this valve is specifically calibrated for systems that reverse refrigerant flow between heating and cooling modes. This ensures stable operation and proper superheat control regardless of operating mode, making it ideal for year-round heat pump installations.
