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.

Typical Specification
Furnish and install on the plans and described herein, a Caleffi Hydro Separator
as manufactured by Caleffi. Each separator must be designed with an epoxy
resin painted steel body, a chrome plated brass blowdown drain valve with hose
connection and automatic brass air vent. The separator design must include
sweat or NPT union fittings. Each separator shall be Caleffi model NA548 or
approved equal. (See product instructions for specific installation information.)

Flow Capacity
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.
