AIRFLOW CAPACITIES
600-1,900 CFM
[283-897 L/s]
Rheem®Indoor Coils are designed for use with Rheem outdoor units and are available for vertical upflow or downflow,
and horizontal left or horizontal right airflow. When matched
with Rheem outdoor units, the coils provide a nominal
capacity of 24,000 to 60,000 BTU/HR [7.03 to 17.6 kW].
■ Constructed of aluminum fins bonded to internally
grooved copper tubing.
■ Coils are tested at the factory with an extensive refriger-
ant leak check.
■ Coils have sweat refrigerant connections.
■ Ideally suited for new installations or add on air
conditioning.
■ Feature two sets of
3
/4" [14.1 mm] N.P.T. Condensate
drain connections for ease of connection.
■ Coils are AHRI certified for system application with variety
of Rheem outdoor units.
■ Condensate drain pan is constructed of high grade, heat
resistant, corrosion free thermal-set material.
■ Compatible with Germicidal Light System (UV resistant)
■ Bi-Directional airflow eliminates the need to switch any
internal components from horizontal left to right.
■ Unique drain pan design maximizes application flexibility
and condensate removal.
