Dans la première étape de rotation, lesdites aubes sont refroidies entre 0° et 10 °C environ. Dans une deuxième étape de rotation lesdites aubes sont mises en contact avec des moyens de balayage de réfrigérant qui retirent l'eau froide de la surface des aubes. Dans la troisième étape de rotation, lesdites aubes sont mises en contact avec le courant d'air et de la vapeur d'eau est condensée à la surface desdites aubes. Dans une quatrième étape de rotation, ladite eau condensée est collectée dans ledit contenant d'eau froide puis est finalement dirigée vers les moyens potabilisateurs.
