Model nomenclature
How to read the code of this model.
-
A
Model code (series): EK-K — EK-K - blast freezer
-
B
Fan direction: b — Blowing fan
-
C
Number of fans: 2 — Number of fans (one digit).
-
D
Fan diameter: 50 — Ø500 mm
-
E
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.
-

Dimensional data - tube rows: E — 6 tube rows
-
G
Fin spacing: 10 — Fin spacing about 10 mm
-
H
Generation code: B — Generation B
-
I
Fan data: 22 — Ø500: 400V/3Ph/50Hz, 4-pole
