Model nomenclature
How to read the code of this model.
-
A
Model code (series): EB — EB - economical unit cooler
-
B
Number of fans: 4 — Number of fans (one digit).
-
C
Fan diameter: 25 — Ø250 mm
-
D
Dimensional data - coil size letter: A — First letter of Karyer's "dimensional data". With the fan count and diameter it fixes the finned coil length and the tubes per row (one casing size). It is a catalogue size index, not a measure: take dimensions from the model datasheet.
-
E
Dimensional data - tube rows: A — 2 tube rows
-
F
Fin spacing: 6 — Fin spacing about 6 mm
-
G
Generation code: B — Generation B
-
H
Fan data: 05 — Ø200: 230V/1Ph/50Hz, 4-pole; Ø250: 230V/1Ph/50Hz, 4-pole; Ø300: 230V/1Ph/50Hz, 4-pole
