Model nomenclature

How to read the model codes of this series, with an example.

A
Series OA/OB = OA = vertical, OB = horizontal oil cooler.
C
Fan rows (optional "Nx") — Catalogue: "Fan Row no." (number before x/X). — = absent: 1 fan row2x = 2 fan rows
D
Number of fans per row — Digit 1-9; total fans = fan rows x this digit.
E
Fan diameter — Two digits = diameter / 10 (91 = Ø910). 50 = Ø500 mm63 = Ø630 mm
G
Coil tube rows (2nd dimensional letter) C = 4 tube rowsD = 5 tube rows
H
Fin spacing — Catalogue fin-spacing code. 1 = 2.1 mm5 = 2.5 mm
I
Generation code — Catalogue: "Generation Code". A = generation A
J
Fan data (fan motor code) — Catalogue: "Fan Data". Two digits select the fan motor (supply, poles); the meaning is series-specific. 01 = single-phase 230 V 50 Hz, 6-pole AC fan (in this series)09 = single-phase 230 V 50 Hz, 4-pole AC fan (in this series)
