Abstract
A silver controller comprising a container, a core member fitted within the container, a filler material around the core member, and a fluid deflector extending around the filler material. The container has an inlet and an outlet and a base. The inlet is located at a higher level than the outlet. The core member has an aperture that is distal the base. The core member has a flange that extends outwardly above the aperture of the core member. The filler material is a metal above silver in the electromotive force series. The fluid deflector is connected to the flange and extends downwardly therefrom so as to be below the aperture in the core member. A plating shield is placed exterior of the fluid deflector. The plating shield is connected to the flange member at one end and generally abuts the bottom of the container at the other end. The plating shield is of a perforated metal suitable for allowing the passage of fluids therethrough. A conductive member is in electrical contact between the filler material and the plating shield.
