7. HYDRONIC GROUP DATA
7.1
USEFUL HEAD
The characteristic head-flow curves net of pressure drops of the hydronic kit are shown below. On each curve the optimal working point corre-
sponding to condition (1) of the technical data table is highlighted.
The system must be designed in such a way as to guarantee the nominal flow rate relative to the working points shown below.
