This is a copper-brazed plate heat exchanger. Copper is solder, which is equivalent to glue, and is used to weld each piece together. Therefore, there is also copper in the channel, which will come into contact with water. It is not recommended to use it if seawater is used, because seawater has a high salt content and contains microorganisms, which will not only corrode copper but also stainless steel.
