Effective corrosion protection coating for brazed plate heat exchangers

Modern heating systems are accompanied by the treatment of heating water to avoid undesirable calcifications. The water treatment according to VDI 2035 specifies demineralized or softened water for heating systems. The so-called deionized water (fully demineralized water) increases the probability of corrosion for the essential component of the system - the copper-brazed plate heat exchanger.

VAU Thermotech has developed an effective corrosion protection coating for copper-brazed plate heat exchangers together with a cooperation partner which prevents detaching of metal ions and guarantees resistance to demineralized water.

This innovative solution offers the advantage that water which is not in the range for copper-brazed plate heat exchangers can also be used.  Our entire brazed product range is available with anti-corrosion coating. There is no need to rebuild the existing connections when switching to a corrosion protection coated heat exchanger. The new type of heat exchanger smoothly fits in the existing system.

We proudly present cost-optimized efficient coated stainless steel plate heat exchanger without non-ferrous metals.
