All the performances (Cooling capacity, unit power input in cooling and EER) are based on the following conditions: evaporator 12.0/7.0°C; ambient
35.0°C, unit at full load operation; operating fluid: Water ; fouling factor = 0.
(*) IW: Ivory White; GPSS: Galvanized and Painted Steel Sheet; PHE: Plate Heat Exchanger; S&T: Single Pass Shell & Tube; MCH: Microchannel; CC:
Closed Cell; DPT: Direct Propeller Type; DOL: Direct On Line - VFD: Inverter - BRS: Brushless
(**) Sound power level (referred to evaporator 12/7°C, ambient 35°C full load operation) are measured in accordance with ISO 9614 and Eurovent 8/1
for Eurovent certified units. The certification refers only to the overall sound power level, the sound pressure is calculated from the sound power level and
are for information only and not considered binding.
The minimum capacity indicated is referred to unit operating at standard Eurovent conditions.
Dimensions and weights are for indication only and not
considered binding. Before designing the installation, consult the official drawings available from the factory at request. All the data are referred to
standard unit without options. Data are subject to change without notice.
