ED-DC (Double Flow)

A ED-DC - B 1 C 30 D A E C F 4 - G A H 21

• A
  Model code (series) ED-DC = ED-DC - double-flow CO₂ (R744) DX 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. 30 = 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). C = 4 tube rowsE = 6 tube rows
• F
  Fin spacing — Nominal fin spacing in mm (1-2 digits). Karyer catalogue: 4=4.00, 7=7.00. The exact pitch is per model (e.g. 4 covers 3.8 to 4.6 mm). 4 = Fin spacing about 4 mm7 = Fin spacing about 7 mm
• G
  Generation code — Karyer design generation letter; Karyer publishes no further decoding. A = Generation A
• H
  Fan data 21 = Ø300: 230V/1Ph/50Hz, 4-pole; Ø350: 230V/1Ph/50Hz, 4-pole
