Legend:
* 30H 043 to 280 unit range (see front cover)
** Net nominal cooling capacity = gross cooling capacity minus the water pump heat against the internal evaporator pressure drop
Nominal Eurovent conditions: evaporator entering/leaving water temperature 12°C and 7°C. Condenser entering/leaving water temperature 30°C and 35°C.
*** Standardised conditions: evaporator entering/leaving water temperature 12°C and 7°C.
Condensing temperature dew point 50°C. Fluid temperature = condensing temperature at dew point - refrigerant glide - 5 K subcooling.
**** The 30H* units have a nitrogen holding charge only.
