Model nomenclature
How to read the code of this model.
-
A
Series: BC/BD — BC = vertical, BD = horizontal dry cooler (air flow bottom to top).
-
B
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: 3 — Digit 1-9; total fans = fan rows x this digit.
-
E
Fan diameter: 80 — Ø800 mm
-
G
Coil tube rows (2nd dimensional letter): C — 4 tube rows
-
H
Fin spacing: 5 — 2.5 mm
-
I
Generation code: B — generation B
-
J
Fan data (fan motor code): 01 — fan motor code; supply/poles vary with diameter
