Description
The Rheem-Ruud RCHZ4821STANVU is a cased evaporator coil engineered for reliable, high-efficiency residential and light commercial cooling applications. Designed to pair seamlessly with compatible Rheem and Ruud condensing units, this coil comes factory-equipped with a thermostatic expansion valve (TXV) and an integrated drain pan, delivering a complete, installation-ready solution for HVAC professionals.
Precision Refrigerant Metering with Factory-Installed TXV
The factory-installed thermostatic expansion valve (TXV) provides precise refrigerant flow control, optimizing system efficiency across a wide range of operating conditions. Unlike fixed-orifice metering devices, the TXV automatically adjusts refrigerant flow in response to changing load demands — helping to maintain consistent superheat, protect the compressor, and maximize system SEER ratings.
Key Features
- Cased coil design for easy installation in upflow, downflow, or horizontal applications (verify orientation compatibility)
- Factory-installed TXV for accurate refrigerant metering and improved system efficiency
- Integrated drain pan for reliable condensate management and reduced installation time
- 21″ cabinet width designed to fit standard air handler and furnace configurations
- Engineered for compatibility with Rheem and Ruud condensing units and air handlers
- Durable construction built to Rheem-Ruud quality standards for long service life
- Designed for use with common residential refrigerants — verify system refrigerant compatibility prior to installation
Integrated Drain Pan
The built-in drain pan captures condensate produced during the cooling cycle, channeling moisture away from the air handler cabinet and surrounding structure. This factory-integrated feature simplifies installation and helps protect against water damage, making the RCHZ4821STANVU a practical choice for both new installations and system replacements.
Designed for System Compatibility
As part of the Rheem-Ruud product family, the RCHZ4821STANVU is engineered to work within matched system configurations, supporting optimal efficiency ratings when paired with approved outdoor condensing units. Always consult Rheem-Ruud’s approved system matchup documentation to confirm compatibility and certified efficiency ratings for your specific installation.
Applications
- Residential split-system air conditioning and heat pump installations
