Description
The Rheem-Ruud RCFZ4821STANMC is a 4-ton cased evaporator coil engineered for dependable residential and light-commercial cooling applications. Designed to pair with Rheem-Ruud split-system air conditioners and heat pumps, this coil delivers consistent, efficient heat transfer and is factory-equipped with a thermostatic expansion valve (TEV) for precise refrigerant metering and optimized system performance across a wide range of operating conditions.
Key Features
- 4-ton (48,000 BTU/hr) nominal cooling capacity
- Cased design for easy installation in upflow, downflow, or horizontal applications (verify orientation compatibility)
- Factory-installed thermostatic expansion valve (TEV) for accurate refrigerant flow control and improved efficiency
- Designed for use with Rheem-Ruud split-system air conditioners and heat pumps
- Durable construction with high-quality coil materials for long service life
- Engineered for compatibility with current Rheem-Ruud condensing units
Why Choose a TEV-Equipped Coil?
A thermostatic expansion valve actively modulates refrigerant flow in response to changing load conditions, maintaining optimal superheat at the coil outlet. This results in more stable system operation, improved energy efficiency, and reduced risk of compressor damage from liquid slugging — making it the preferred choice over fixed-orifice metering devices in modern HVAC installations.
Applications
- Residential split-system central air conditioning
- Heat pump systems requiring a matched indoor coil
- Replacement or new-construction installations requiring a 4-ton indoor coil
- Compatible with Rheem-Ruud air handlers and furnace-coil configurations
