(a)Coil width = Length in the direction of a coil header, typically vertical.

(b)“Hydronic and DX coil data” width dimensions apply only to DX coils (all unit sizes), 1-row standard ca- pacity hydronic coils (unit sizes 012 through 036), and 4- and 6-row standard capacity hydronic coils (54 through 90).

(c)Coil length = Length of coil in direction of the coil tubes, typically horizontal and perpendicular to airflow.

(d)“High-capacity hydronic coil data” width dimensions apply only to 1-row standard capacity hydronic coils (unit sizes 054 through 090) and 2-, 4-, and 6-row high capacity hydronic coils (all unit sizes).

(e)The minimum waterflow at 1.5 fps tubeside velocity is to ensure the coil self-vents properly. There is no minimum waterflow limit for coils that do not require self venting.

(f)Maximum gpm limits are to prevent erosion and noise problems.

(g)DX coil height and width dimensions are same as comparable hydronic coils. Four- and six-row DX coil dry weight dimensions are same as comparable 4- and 6-row hydronic coils. A 3-row DX coil dry weight is 25% less than a comparable 4-row hydronic coil. Internal volumes are approximately 6% less than comparable hydronic coils.
