Low-loss header MVW DN 20 (3⁄4")

for boilers with integrated pump

By means of the conversion kit (item no. 3143), the modular distribution manifolds

get a bypass which connects the flow and return line without causing any resistance

(low-loss header).

It must be considered that the pump of the boiler circuit must deliver a higher flow

rate than the consumer pumps need in total. Otherwise, unwanted circulations occur

on the right or left end of the low-loss header. In that case a hydraulic separator (item

no. 3142 or 31421) must be installed below a distribution manifold.

Please note:

When you plan the system you must already check whether

a low-loss header can be used. In combination with central

heating boilers, hydraulic separators must be installed

below / upstream of a distribution manifold as the boiler

delivers a flow rate with a high temperature difference

(leads to unwanted circulation in low-loss headers).
