a-HWD2 are the new Climaveneta ducted high head hydronic terminals. The possibility of vertical and / or horizontal installation, compactness and the wide range of accessories or ductwork panels, make these units very flexible in installation and adaptable to any system type. The internal insulation of a-HWD2 units ensures operation with excellent acoustic comfort.
P.S. The picture is refered to the unit with mounted valves and plenum with spigots.
