Rheem®Indoor Coils are designed for use with Rheem outdoor units and are available in upflow, downflow and horizontal configurations. All configurations are convertible to
any of the other airflow possibilities.
The MultiFlex
®
coils provide capacities ranging from 18,000
to 60,000 BTUH [5.27 to 17.58 kW].
The patented single-row, single-coil pleated concept results
in extremely low pressure drops and corresponding easy
cleaning.
Front refrigerant and drain connection add to ease of
installation. Coils can be field modified for left side refrigerant connections and side connections on some models.
Double stacked coils are side refrigerant connect only with
front condensate.
Engineering Features
■ Constructed of enhanced aluminum fins bonded to inner
grooved copper tubing.
■ Coils have sweat fitting refrigerant connections.
■ Primary condensate drain connections are
3
/4" [19 mm]
F.N.P.T.
■ Coils are A.R.I. certified for system application with a wide
variety of Rheem outdoor units.
■ Condensate drain pan is constructed of a high grade, heat
resistant, corrosion free polymer material.
■ Double-wall construction offers sturdiness along with
dead air space insulation and sound attenuation.
■ Internally checked TX valves are used on high efficiency
heat pump coils for quieter refrigerant metering.

RXCT- EXPANSION VALVE CONVERSION KIT FOR RCBA INDOOR COILS
Use an expansion valve kit to convert RCBA- indoor coils to RCGA-/RCGJ-/RCHA- and RCHJ- Coils
Kits may be used for conversion of side or front connect with the exception of the RXCT-CHF and RXCT-CHG, which is side connect only.
