19 HYDRAULIC SEPARATOR KIT MEASUREMENTS AND FITTINGS (OPTIONAL)

The hydraulic separator (compensator) is a particularly signif-
icant part inside the hydraulic circuits.
It is an open manifold (1) which places system flow and return
in communication, creating 2 circuits: a primary circuit (boiler
- manifold) and a secondary circuit (manifold-system).
The former circulates by the boiler pump, while the latter runs
on the correct thermal gradient (and therefore the correct water
flow rate), as defined by the system's design.

The above graph provides information to enable you to choose the
most appropriate separator based on the design data.
Example:
let us assume you have two VICTRIX PRO 120 1 I with a heat output
of 243.4 kW (209.364 kcal/h) for 50/30 °C.
1st case: The design ∆T of the system is 20 °C, with a flow rate of
10.468 l/h. The ideal separator is the 200 kW separator kit code
3.021377 (see the area between the horizontal yellow line and the
pink one).
2nd case: The design ∆T of the system is 15 °C, with a flow rate of
13.957 l/h. The separator that can be used is the 350 kW separator
kit, code 3.023965 (we are at the limit of the pink and black hori-
zontal line).
3rd case: The design ∆T of the system is 10 °C, with a flow rate of
20.936 l/h. The ideal separator is the 400 kW separator kit code
3.021378 (see the area between the horizontal black line and light
blue one).
4th case: The design ∆T of the system is 7 °C, with a flow rate of
29.909 l/h. The ideal separator is the 600 kW separator kit code
3.023962 (see the area between the horizontal light blue line and
the orange one).

It is advisable to include a hydraulic compensator (1) every time
the overall flow rate required by the system is greater than what
the boiler is able to supply. The maximum flow rate at the inlet
is the generally adopted sizing method (see the graph below for
separator selection).
