Rheem-Ruud RCBA-3765T Evaporator Coil

The Rheem RCBA-3765T Evaporator Coil is an uncased Multiflex replacement coil engineered for precise performance in 30K to 36K BTU/h applications. Designed for maximum versatility, this 2.5 to 3 ton coil features a multiflex design compatible with upflow, downflow, and horizontal airflow configurations. The assembly utilizes high-grade copper tubing bonded to enhanced aluminum fins (18 FPI) to optimize thermal transfer and maintain system efficiency. With an airflow capacity ranging from 600 to 2000 CFM, this unit integrates seamlessly with Rheem outdoor units using either R-22 or R-410A refrigerants. As a direct replacement for legacy models RCBA-3765G and RCBA-3765A, it features a tin-plated coil construction to mitigate formicary corrosion and includes a high-temperature polymer condensate pan for long-term reliability. The sweat fitting connections and 3/4" F.N.P.T. primary drain facilitate efficient field installation for technical professionals.
