Product Overview

Hydronic separator-manifold
HydroLink
™
series 559
Function
The Hydrolink, a new device combining a hydronic separator and
distribution manifold, is used in heating and air-conditioning
systems to allow different heat adjustments of the various rooms
when there is only one boiler or chiller.
The various configurations are compact, and can be easily fitted in
any kind of hydronic circuit, with the advantages of ease of
installation and a saving of useful living space.
