Model nomenclature
How to read the code of this model.
-
A
Model code (series): EA-DA — EA-DA - fruit and vegetable unit cooler (blowing fans)
-
C
Number of fans: 4 — Number of fans (one digit).
-
D
Fan diameter: 50 — Ø500 mm
-
E
Dimensional data - coil size letter: B — 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.
-
F
Dimensional data - tube rows: E — 6 tube rows
-
G
Fin spacing: 7 — Fin spacing about 7 mm
-
H
Generation code: B — Generation B
-
I
Fan data: 21 — Ø350: 230V/1Ph/50Hz, 4-pole; Ø500: 230V/1Ph/50Hz, 4-pole
