Hydronic separator-manifold
HydroLink™
Function
The Hydrolink, a new device combining a hydronic separator and
distribution manifold, is used in heating and air-conditioning
systems to allow di erent heat adjustments of the various rooms
when there is only one boiler or chiller.
The various
are compact, and can be easily
in
any kind of hydronic circuit, with the advantages of ease of
installation and a saving of useful living space.
