Abstract

The invention concerns an installation for stirring a low-conductivity fluid, comprising: a cylindrical chamber (1) for receiving the fluid; a first winding (5) including two first coils (51, 52) respectively formed around two separate first regions of the chamber (1) and connected oppositely in series, the terminals of the first winding (5) being adapted to be connected to the terminals of a first capacitor (C) and to the terminals of an alternating current voltage source (3); and at least a second winding (6) including two second coils (62, 62) respectively formed around two separate second regions of the chamber (1) and connected oppositely in series, one of which is located between the two separate first regions of the chamber, and connected oppositely in series, the terminals of the second winding (6) being adapted to be connected to the terminals of a second capacitor (C').
