It should be noted that decalcification by means of ion exchange does not reduce the con-
ductivity. For this reason, use a full stainless steel exchanger from 500 µS/cm. It can roughly
be calculated that 14° dH corresponds to a conductivity of 14° dH * 35 = 490 μS/cm. Thus,
as a precaution, a full stainless steel exchanger must be used. In addition, fresh water
stations must be grounded so that no current flow over the plate heat exchanger or the piping
is performed.
