Description
Overview
The Copeland 066538 (Model HFES 10 SC 5FT 5/8 x 7/8 ODF S/T) is a heavy-duty, externally equalized Thermal Expansion Valve (TXV) engineered for reliable refrigerant metering in medium-temperature commercial refrigeration systems. With a 10-ton capacity rating and compatibility with R404A, R507, and R502 refrigerants, this valve delivers precise superheat control to protect compressors and maximize system efficiency.
Key Features
- 10-Ton capacity rating for commercial-scale refrigeration applications
- Compatible refrigerants: R404A, R507, and R502
- Medium temperature charge for reliable operation across typical commercial refrigeration temperature ranges
- Externally equalized design compensates for pressure drop across the evaporator, ensuring accurate superheat control
- Straight body configuration for straightforward inline installation
- 5/8″ x 7/8″ ODF sweat connections for secure, leak-free brazed joints
- 5-foot capillary tube provides flexible bulb placement for optimal sensing
- Sweat (solder) end connections for compatibility with standard copper tubing
Application
Designed for medium-temperature commercial refrigeration systems including walk-in coolers, reach-in cases, and display cases. The external equalizer port makes this TXV ideal for evaporators with significant refrigerant-side pressure drop, ensuring consistent superheat control even under variable load conditions.
