Hydraulic characteristics
The hydronic separator should be sized according to the maximum
flow rate at the inlet. The selected design value must be the
greatest between the primary circuit and the secondary circuit.

Application
The hydronic separator creates a zone with a low pressure loss, which enables
the primary and secondary circuits connected to it to be hydraulically independent
of each other; the flow in one circuit does not create a flow in the other.
