Engineering data

A cast section protection function is integrated in the MGK. This prevents
stresses in the material by limiting the maximum temperature differential
between the flow and return. As of 28 K, the output is reduced. If 38 K is
nevertheless reached, the burner shuts down briefly without a fault message.
This characteristic must be taken into account when selecting the components
(e.g. pumps, heat exchanger and cylinder).
Excessive flow velocities may lead to erosion.
Maximum flow rate at Q
The following Wilo and Grundfos pumps represent recommendations in
conjunction with the installation of a MGK with a low loss header.
Select pumps in accordance with the respective system if no low loss header
is to be installed.
