Model nomenclature
How to read the model codes of this series, with an example.
-
A
Model code (series) EM = EM - low-speed ceiling-type unit cooler
-
B
Number of fans — Number of fans (one digit).
-
C
Fan diameter — Fan diameter in cm (two digits; x10 = mm), e.g. 30=Ø300, 63=Ø630, 91=Ø910. 20 = Ø200 mm25 = Ø250 mm30 = Ø300 mm35 = Ø350 mm
-
D
Dimensional data - coil size letter — 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 — Second letter of the dimensional data = number of tube rows (coil depth): A=2, B=3, C=4, D=5, E=6, G=8, I=10, K=12 (alphabet position + 1). B = 3 tube rowsC = 4 tube rows
-
F
Fin spacing — Nominal fin spacing in mm (1-2 digits). Karyer catalogue: 4=4.20, 6=6.00. The exact pitch is per model (e.g. 4 covers 3.8 to 4.6 mm). 4 = Fin spacing about 4 mm
-
G
Generation code — Karyer design generation letter; Karyer publishes no further decoding. C = Generation C
-
H
Fan data 21 = Ø300: 230V/1Ph/50Hz, 4-pole; Ø350: 230V/1Ph/50Hz, 4-pole23 = Ø250: 230V/1Ph/50Hz, 4-pole25 = Ø200: 230V/1Ph/50Hz, 4-pole
