Product Overview

Construction details
Isolating the air vent valve
In flanged separators, the air vent is
isolated manually, using a shut-off ball
valve. In union separators, however, the
air vent body is automatically isolated by
the check valve, which closes when the
air vent body is removed.
Dirt removing element
A vital function of the hydronic separator
is carried out by the dirt removing element
inside the device.This makes it possible
to separate and collect any impurities
which may be present in the system.
These impurities are removed by means
of the drain valve, which can be connected
to a discharge pipe, placed at the bottom
of the separator.
Insulation
Hydronic separators are available complete with a hot preformed
insulation shell. In the flanged series, up to 4”, the insulation is
made of a shell in expanded polyurethane foam covered with an
aluminium layer. In the threaded version the insulation is made of a
pre-formed shell in double density closed cell expanded PEX.
This insulation ensures not only perfect heat insulation but also the
tightness required to prevent atmospheric water vapors from entering
the unit. For these reasons, this type of insulation can also be used in
cooling water circuits, as it prevents the formation of condensate on the
surface of the separator body.
Hydraulic characteristics
The hydronic separator should be sized according to the maximum
flow rate value at the inlet.The selected design value must be the
greatest between the primary circuit and the secondary circuit.
