Construction details
Isolating the air vent valve
The air vent (A), replacement part number 501502, is isolated
manually, using a shut-off ball valve (B), replacement part number
NA39589.
Dirt removing element
The HYDROCAL dirt removing element
separates and collects any impurities
present in the system.
These impurities are removed by the
drain valve (C) replacement part number
NA39588, which can be connected to a
discharge pipe, the bottom of the
separator.
Insulation
The HYDROCAL is 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 HYDROCAL 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.
