* Standardised Eurovent conditions: evaporator entering/leaving water temperatures = 12°C/7°C, outside air temperature = 35°C
Net cooling capacity: Gross cooling capacity minus the water pump heat against the internal evaporator pressure drop.
** The compressor size corresponds to the nominal capacity in tons (1 ton = 3.517 kW).
