(1) Based on FC units performance at 16/10°C return/supply temperatures, 35°C ambient, 20% ethylene glycol.
(2) EER = DX cooling output / (compressor input power + fan input power)
(3) ESEER / SEER based upon unit operating at 12 / 7 °C return / supply temperature, 35°C ambient.
(4) Nominal Free Cooling output at 16/10°C return/supply temperatures, 2°C ambient, 20% ethylene glycol.
(5) Ambient temperature that maximum nominal DX duty can be achieved using Free Cooling only.
(6) This is a nominal figure based on full compressor duty, actual turndown depends on both condensing and evaporating temperatures.
(7) Based on standard unit without options, machine weight includes refrigerant charge, operating weight includes refrigerant charge and water volume.
For unit weights with waterside options fitted please contact Airedale.
(8) For minimum system water volume calculation, refer to Design Features & Information - Minimum System Water Volume Calculations.
