Model nomenclature

How to read the code of this model.

  • A
    Model code (series): EK-K — EK-K - blast freezer
  • B
    Fan direction: s — Sucking (suction) fan
  • C
    Number of fans: 6 — Number of fans (one digit).
  • D
    Fan diameter: 50 — Ø500 mm
  • E
    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.
  • F
    Dimensional data - tube rows: G — 8 tube rows
  • G
    Fin spacing: 10 — Fin spacing about 10 mm
  • H
    Generation code: B — Generation B
  • I
    Fan data: 10 — Ø500: 400V/3Ph/50Hz, 4-pole
