Abstract (en)

The object of the present invention is an electrostatic powder coating method for metal tanks (1) internally provided with a coil-wound heat exchanger (5). The method provides for an application step of the powder during which the powder dispensing lance runs exclusively through a stretch (H1) just sufficient to deposit powder on the entire surface of said coil (5) optionally followed by further steps in which said powder dispensing lance operates in stretches (H2, H3) different from the stretches (H1, H2) run through in previous steps.
