TCC24X18G-18, TCC24X20G-18
(1) Based on AC units performance at 13/7°C return/supply temperatures, 35°C ambient, 100% water.All performance data is supplied in accordance with BS EN 14511-1:2013
(2) EER = DX cooling output / (compressor input power + fan input power)
(3) ESEER 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.
(9) Height based on standard fan, for optional fan dimensions please contact Airedale
