Model nomenclature

How to read the code of this model.

  • A
    Model code (series): EA — EA - general-purpose unit cooler
  • B
    Number of fans: 1 — Number of fans (one digit).
  • C
    Fan diameter: 63 — Ø630 mm
  • D
    Dimensional data - coil size letter: E — 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: 7 — Fin spacing about 7 mm
  • G
    Generation code: C — Generation C
  • H
    Fan data: 11 — Ø630: 400V/3Ph/50Hz, 4-pole

Performance

No glide: dew, mid and bubble point give the same rating.

TD (air − evaporating) must be within 4–10 K; air inlet −40…+20 °C.

R404A, dew point -8 °C, air inlet 0 °C (TD 8 K)

High speed (Δ)
12.430 kW
Low speed (Y)
10.809 kW
