Claims5
A method for providing heat transfer plates with a layer of plastic protecting material which comprises assembling a plurality of heat transfer plates to form a plate heat exchanger having plate interspaces for the through flow of heat exchange fluids, vaporizing said protective material to bring it into the gaseous phase, introducing a gaseous medium comprising said surface protecting material in gaseous form into at least one plate interspace of said plate heat exchanger and causing said material to condense on the surfaces of the heat transfer plates forming said plate interspace.
