Title (EN) ICE MAKING WATER TREATMENT
(FR) TRAITEMENT D'EAU DESTINEE A LA PRODUCTION DE GLACE
Abstract:
(EN) The invention includes a source for hot and/or cold water and a conduit (22, 24) coupling the source to a hose (26) or other outlet. Water flowing through the conduit (22) is treated with electromagnetic radiation generated from one or more electromagnetic coils (34) located proximate the conduit (22) which act as radiofrequency antennae and/or by direct injection into the water of electromagnetic radiation having a preselected frequency through a conductor (119).
(FR) L'invention comprend une source d'eau chaude et/ou froide ainsi qu'un conduit (22, 24) raccordant la source à un tuyau (26) ou à une autre sortie. L'eau s'écoulant dans le conduit (22) est traitée par exposition à un rayonnement électromagnétique généré par une ou plusieurs bobines électromagnétiques (34) situées à proximité du conduit (22) faisant office d'antennes haute fréquence et/ou par injection directe dans l'eau, par l'intermédiaire d'un conducteur (119), d'un rayonnement électromagnétique ayant une fréquence présélectionnée.
