A distributor unit comprises elongated cuboid hollow columns having side walls (7, 8), the interior of which is subdivided by a partition (9) into a flow chamber (11) and a return chamber (12) of a circular flow. All the hollow columns arranged in a panel plane are connected to two transverse distributors (71 and 72) which for each hollow column have a tubular sleeve (75) with an opening (81), which are provided at both ends with oppositely directed internal threads and are coupled by means of bush-shaped coupling nipples (78) in such a way that the hollow columns are also thereby contracted. Also seated in the internal thread is a slide bush (82) which enables adjustment of the cross-section of the opening (81) for the purpose of tuning the volumes in the individual circular flows. The fittings can optionally be provided inside the hollow columns or outside by means of external connections, and the column chambers (11 and 12) can also be arranged consecutively, in particular when they are open towards opposite sides. <IMAGE>
