CASED COILS FOR GAS FURNACES

PRODUCT FEATURES

• Durastar Indoor Furnace cased coils are designed for use with Durastar
outdoor units and are available for vertical upflow or downflow, and horizontal
left or horizontal right airflow. When matched with Durastar outdoor units, the
coils provide a nominal capacity range from 18,000 BTU/HR [5.24 kW] to
60,000 BTU/HR [17.6 kW].

• Constructed of aluminum fins bonded to internally grooved aluminum tubing.

• Coils are tested at the factory with an extensive refrigerant leak check.

• Coils have copper sweat refrigerant connections.

• Feature two sets of 3/4" [14.1 mm] N.P.T. Condensate drain connections
for ease of connection.

• Chatleff metering device connections, at inlet and outlet of TXV and equalizer
connections.

• 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.

• N-Coil design maximizes performance and minimizes height
required at installation.

• Coils are AHRI certified for system application.

AIRFLOW CAPACITY:
600-1,900 CFM [283-897 L/s]
