METHODS OF FORMING PROTECTIVE SURFACE TREATMENTS ON HEAT EXCHANGERS IN-SITU

Disclosed is a method of in-situ application of a conformal surface treatment to an internal surface of a heat exchanger (20) of a chiller (300) comprising providing a surface treatment solution to an inlet of the heat exchanger (20) of the chiller (300), urging a flow of the surface treatment solut...

Zusammenfassung:Disclosed is a method of in-situ application of a conformal surface treatment to an internal surface of a heat exchanger (20) of a chiller (300) comprising providing a surface treatment solution to an inlet of the heat exchanger (20) of the chiller (300), urging a flow of the surface treatment solution along a flowpath (50) from the inlet past a plurality of heat transfer tubes (14) to an outlet of the heat exchanger (20) of the chiller (300), collecting the surface treatment solution, forming the conformal surface treatment along an internal surface of the first manifold (12), the plurality of heat transfer tubes (14), the second manifold (16), and a plurality of interconnections therebetween, stopping the flow of the surface treatment solution, and removing the surface treatment solution from the chiller (300).
