Rheem-Ruud RCBA-2457T Evaporator Coil

The Rheem RCBA-2457T Uncased Multiflex Evaporator Coil is a high-efficiency slab-coil design engineered for versatility in residential and light commercial HVAC applications. This 1.5 to 2-ton replacement coil delivers a nominal cooling capacity of 18,000 to 24,000 BTU/h and is the certified direct replacement for the obsolete RCBA-2457G and RCBA-2457GP models. Designed for professional installation, it features bi-directional airflow capabilities, allowing for seamless integration into upflow, downflow, and horizontal (left or right) configurations without complex internal component modification.

Constructed with tin-plated copper tubing and high-performance aluminum fins (18 FPI), the RCBA-2457T provides superior corrosion resistance in harsh environments. The unit includes a high-grade, heat-resistant, thermal-set drain pan and is fully compatible with R-410A and R-22 refrigerants. Professional-grade front refrigerant and drain connections facilitate faster sweat-type installations and maintenance in tight 14-inch furnace cabinets.

Key Benefits:

• Corrosion-Resistant Construction: Features tin-plated copper headers and tubing to prevent formicary corrosion and extend service life.
• Multiflex Installation: Supports vertical and horizontal airflow configurations with included universal duct flanges.
• Optimized Heat Transfer: Aluminum fins bonded to internally grooved copper maximize thermal exchange and dehumidification performance.
• UV Resistance: Compatible with germicidal UV light systems to maintain indoor air quality.
• Low Pressure Drop: Engineered for 600–800 CFM to maintain system efficiency and reduce blower motor strain.

Common Questions:

Is the RCBA-2457T compatible with older R-22 systems?
Yes, this coil is designed for dual compatibility with R-22 and R-410A refrigerants, provided the appropriate metering device is used for the specific outdoor unit match-up.

Does this unit include the metering device?
The unit comes factory-installed with a #57 orifice piston. For high-efficiency SEER requirements, it may be converted to a TXV (Thermal Expansion Valve) using a field-installed kit.

Will this fit in a standard 14-inch furnace cabinet?
Yes, with a width of 13.13 inches and an uncased design, it is specifically sized for standard narrow-width furnace applications.
