Abstract (en)
A method of coating an internal surface of an assembled heat exchanger is provided. The heat exchanger (2) comprising a first passage for a first heat exchange fluid, and a second passage for a second heat exchange fluid. The first and second passages are separated by at least one heat transfer element. The heat transfer element has a first surface facing the first passage. The method comprises; pre-treating the first surface by circulating at least one pre-treatment liquid through the first passage of the heat exchanger (2) and a pre-treatment liquid storage (38) separate from the heat exchanger, and electroless nickel plating the first surface by circulating a solution comprising nickel ions through the first passage of the heat exchanger (2) and a solution container (40) separate from the heat exchanger (2). A heat exchanger comprising a nickel plating is also disclosed.
