Model nomenclature

How to read the code of this model.

  • A
    Model code (series): EA-DI — EA-DI - cold-store evaporator, fans inclined 45° to the coil
  • B
    Number of fans: 2 — Number of fans (one digit).
  • C
    Fan diameter: 91 — Ø910 mm
  • D
    Dimensional data - coil size letter: G — 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: E — 6 tube rows
  • F
    Fin spacing: 4 — Fin spacing about 4 mm
  • G
    Generation code: A — Generation A
  • H
    Fan data: 04 — Ø910: 400V/3Ph/50Hz, 6-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)
80.890 kW
Low speed (Y)
