Information regarding the corrosive effect of water on soldered plate heat exchangers
The soldered plate heat exchanger is made from stainless steel 316 or 304 and copper solder. In this case, the
resistance of both stainless steel and copper must be considered. Particular attention must be paid to compli-
ance with the values in the following table. In addition, mixed installations (especially with galvanized pipes)
must be avoided.

All specified details are for information only and cannot be used as a basis for warranty claims. To prevent pit-
ting below coverings, all types of incrustation and contamination must be avoided in the heat exchanger. Fur-
thermore, the water flow rate and contamination with S0
solution (a function of the oxidising compounds, such as oxygen, hypochlorous acid and sodium carbonate)
must also be observed. In practice, the fresh water module shows up to a value of 15 ° d hardness high resis-
tance to calcification. At higher values, a decalcification plant can reduce the maintenance interval
significantly!
