This is for the cooled and cooling water (DP = pressure drop from pressure drop curves).A filter strainer must be added in the water circuit of the evaporator and the condensor. A flow switch must be providedat the evaporator side. Min. water volume system applicable at nominal conditions.Nominal cooling capacities are based on the following conditions: Evaporator: 12 °C/7 °C, condenser 30 °C/35 °CThe sound power level is an absolute value indicating the ’’power’’ which a sound source generates.The sound data is valid at nominal operation condition dB(A) = A-weighted sound power level (A-scale according to IEC)Reference acoustic pressure 0 dB = 1 pW.
