Based on AC units performance at 12/7°C return/supply temperatures, 35°C ambient, 100% water. All performance data is supplied in accordance
with BS EN 14511-1:2018.
(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 fi 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.
(6)
EC fans and no pumps.
(7)
Data quoted at design fl ow-rate, 7°C supply temperature and 35°C ambient, 100% water.
(8)
Starting amps refers to the direct on line connections.
Pump electrical data is available from Airedale upon request.
