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.
(1) In accordance with standard EN14825:2013, comfort low temperature, average climate. SEER and µs values applicable Ecodesign regulation: (EU) No
2016/2281.
(2) PHE: Plate Heat Exchanger; S&T: Single Pass Shell & Tube; MCH: Microchannel; DPT: Direct Propeller Type; DOL: Direct On Line - VFD: Inverter
(3) 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. All data are subject to change without notice.
(4) The value refers to the pressure drops in the evaporator only.
(5) Option FANMOD consist in Continuous Fan Speed Regulation and improves part load operation. Single-V units are standardly equipped with continuous
fan control. Multi-V units require opt 99 – VFD fans
