a-HWD2 102 - 902
a-HWD2 is the new ducted high head hydronic terminals range. The possibility of vertical and/or horizontal installation, compactness and the wide range of accessories or duct-work 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 referred to the unit with mounted valves and plenum with spigots.
