Flanged distribution manifolds allow the installation of DN 40, 50 and 65 distribution and regulating groups in heating and air-conditioning systems, connecting them to the heat generator, hydraulic separator or inertial buffer storage. The F06.DN40-50 series, with DN 100 main connections, is equipped with G 2 1/2 secondary connections with running nut and 300 mm centre distance between the outlets, for the connection to the DN 40 and DN 50 distribution and regulating groups. The F07.DN65 series, with DN 150 main connections, is equipped with DN 65 flanged secondary connections and 300 mm centre distance between the outlets, for the connection to the DN 65 distribution and regulating groups. The manifolds are made of painted steel and are equipped with insulation designed to be used in both heating and air-conditioning systems. The floor support is height-adjustable. The available accessories, such as reductions and elbow fittings, allow manifolds of different sizes to be connected together and systems to be created that rest on adjacent walls.
