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: 45 — Ø450 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.
-
