DCC Mechanical Data - Extra Quiet
(1) Based on units performance at 12/7°C return/supply temperatures, 35°C ambient, 100% water. All performance data supplied in accordance with BBS EN14511-1:2013
(2) EER = DX Cooling Output / (Compressor input power + Fan Input Power),
(3) Based on standard unit without options, operating weight includes refrigerant charge and water volume.
For unit weights with waterside options tted please refer to Airedale.
(4) For minimum system volume, refer to Design Features & Information - Minimum System Water Volume Calculations
(5) Ambient temperature that full Freecool capacity can be achieved
