HydroLink™
Function
The Hydrolink™, combining a hydraulic separator with a
distribution manifold, is used in heating and air-conditioning
systems. It provides a chamber to hydraulically separate the
boiler (or chiller) circuit from the distribution circuits and also
provides a self-contained manifold station that supplies up
to four independently controlled load circuits with the same
supply temperature. Available configurations are compact,
and can be easily installed in any hydronic system, saving
space.
