(1) Nominal Cooling Duties based on 12/7°C evaporator water and 30/35°C condensing water, where output is the chilled water
duty and input is the compressor input power.
All performance data is supplied in accordance with BS EN 14511-1:2013
(2) EER is the Cooling Duty  compressor input power.
(3) For minimum system volume refer to Minimum System Water Volume Calculations .
