AVAILABLE HEAD PRESSURE OF THE UNIT WITH INTEGRATED CIRCULATOR
We reporte below the Head pressure-Water flow characteristic curves without consideration of head losses of the hydronic kit
(which is consisting of the components describe in the Paragraph 5.10) at the maximum speed of the circulator. The optimal
operating point is indicated on each curve under the specified conditions indicated at apex (1) p. 16. The plant system must be
designed so as to ensure the nominal water flow rate corresponding to the operating points indicated below.
