Notes: 1. Coil width = length in the direction of a coil header, typically vertical. 2. Coil length = length of coil in direction of the coil tubes, typically horizontal and perpendicular to airflow.
3. Unit sizes 17-30 have two stacked steam coils. 4. To prevent erosion/noise problems. 5. Coil width = length in the direction of a coil header, typically vertical. 6 . Coil length = length of
coil in direction of the coil tubes, typically horizontal and perpendicular to airflow. 7 . The minimum waterflow is to assure self venting of the coil. There is no minimum water flow limit
for coils that do not require self venting. 8. Minimum airflow limit is for units with hot water, steam, or electric heat. There is no minimum airflow for cooling only units. 9. Due to
moisture carryover limits. 10. Coil weight based on 12 fpi coil.
