DCF Mechanical Data - Regular Quiet
(1) Based on units performance at 15/10°C return/supply temperatures, 35°C ambient, 20% Ethylene Glycol
(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 fitted 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
