We use the same successful collector type as the classic system. These are bar-type distributors, without joints, nickel-plated, brass, nominal diameter 1" or 1¼'' with ¾" thread (Eurocone). The inlet manifold has built-in Allen switches or flow meters, which adjust the flow of each circuit based on the system design. The return collector has a valve for the installation of electrothermal motors (actuators), for the autonomous operation of each circuit. In its supply we connect a 1'' supply nipple with a thermometer and to all the returns 3/4'' return nipples for a better and easier regulation of the circuits. At each output of the collector (input / return) the special TAF part (splitter) which has two Φ10 mechanical clamping sockets.
