Simply ingenious - simply dynamic
Small flows during transit – lots of movement in the ring

With the KHS Multi-Circ Distributor Unit -dynamic- another step towards stagnation prevention has been achieved. With an additional component in the venturi nozzle, the dynamic distribution unit is capable of achieving a maximal flow through of the connected rings even with the smallest volume rates in the distribution / in the riser branch.

Explanation
During small volume flow in transit, ≈ 95 % volume flow is conducted through the ring!!

The KHS Multi-Circ Distributor Unit -dynamic- stands out from the well-known KHS Multi-Circ Distributor Unit -static- in that it reacts and works "dynamically".

In the "Circulation" function, transit is nearly completely closed. The ring is supplied ca. 95 % with circulation volume flow. Starting at the opening point, a continually increasing volume flow is achieved in the direction of transit, during which the ring continues to be strongly flooded. During consumption, transit is completely opened so that the volume flow required for the consumption in the distribution line / in the riser branch as well as the required circulation flow for covering the heat losses in the ring flows.

On account of the described operating principle, the KHS Multi-Circ Distributor Unit -dynamic- can be used in both the PWC as well as in the PWH system with great efficiency. Even at the lowest supply-side volume flows, a volume flows in the ring due to the available pressure difference.
