Notes
- 1 Chilled water (with ethylene glycol at 30%) from 20 to 15°C, ambient air temperature 35°C.
- 2 Ambient air temperature at wich the cooling capacity indicated in point (1) is reached.
- 3 Sound pressure level measured in free field conditions at 1 m from the unit. According to ISO 3744.
- N.B. (1) The nominal inlet/outlet water temperature at note (1) is 3 degrees lower than nominal inlet/outlet water temperature on cooling door to take into account the presence of LPS Leak Prevention System.
