Performances are rated at:
Cooling: ambient air temperature 35 °C; evaporator water temperature in/out 12°C / 7 °C.
Free cooling: ambient air temperature 2 °C; water inlet temperature 15°C, glycol 20%, nominal waterflow, compressors switched off
(1): Sound power level according to ISO 3746.
(2): Sound pressure level measured at 10m from the unit in free field conditions: direction factor Q=2 (according to ISO 3746).
