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)
60.673 kW
Low speed (Y)
51.823 kW

Capacity matrix [kW]

R404A, Dew point; rows: TD = air inlet − evaporating temperature, columns: air inlet temperature. The highlighted cell is the nominal point (SC2). "—": not rated by the manufacturer.
