Model nomenclature
How to read the code of this model.
-
A
Model code (series): ED — ED - double-flow ceiling unit cooler
-
B
Number of fans: 3 — Number of fans (one digit).
-
C
Fan diameter: 30 — Ø300 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: C — 4 tube rows
-
F
Fin spacing: 4 — Fin spacing about 4 mm
-
G
Generation code: C — Generation C
-
H
Fan data: 21 — Ø300: 230V/1Ph/50Hz, 4-pole; Ø350: 230V/1Ph/50Hz, 4-pole; Ø400: 230V/1Ph/50Hz, 4-pole; Ø500: 230V/1Ph/50Hz, 4-pole
