Fin type (optional "t"): t — t: louvered fins (high-efficiency fin surface)
-
C
Fan rows (optional "Nx"): 2 — Catalogue: "Fan Row no." (number before x/X).
-
D
Number of fans per row: 2 — Digit 1-9; total fans = fan rows x this digit.
-
E
Fan diameter: 91 — Ø910 mm
-
G
Coil tube rows (2nd dimensional letter): B — 3 tube rows
-
H
Fin spacing: 1 — 2.1 mm
-
