A halogen generator produces a halogen sanitizing agent to sanitize water in a spa or other water feature. A coaxial wall fitting desirably couples the halogen generator to the water feature. The halogen generator desirably includes a bipolar electrolytic cell in which a center electrode plate rotates between stationary anode and cathode plates. The bipolar electrode includes a plurality of vanes which motivate water flow between the anode and the cathode. The vanes on the rotating electrode also produce a flow of water through the generator. In this manner, the bipolar electrode functions as a impeller to pump water through the halogen generator. The vanes are positioned between the electrode and cathode, and are sufficiently spaced from the cathode to inhibit scale formation on the cathode. The vanes, however, generally do not contact the cathode when rotating. The rotational direction of the electrode relative to the cathode may be reversed periodically and/or the gap spacing between electrode and the cathode may be decreased periodically to enhance removal of scale.
A fitting assembly for coupling a halogen generator to a spa body, said fitting assembly comprising:
A wall fitting assembly for coupling together a spa and a halogen generator disposed externally of said spa, said wall fitting assembly comprising a first member having a peripheral wall and connected to an end cap, and a second member having a peripheral wall engaged with said peripheral wall of said first member, a first fluid passage being surrounded by said peripheral walls of said first and second members and a second fluid passage being surrounded by said peripheral walls of said first and second members, said first fluid passage directly communicating at one end with at least a first orifice formed through said end cap and at an opposite end with a first port, and said second fluid passage directly communicating at one end with at least a second orifice formed through said end cap and at an opposite end with an second port, each of said first and second ports being intended to communicate with either an inlet or an outlet of a halogen generator.
A wall fitting assembly for coupling together a spa and a halogen generator disposed externally of said spa, said wall fitting assembly comprising a first member having a generally annular section, a second member having a generally annular section releasably engaged with said generally annular section of said first member, said annular sections of said first and second members surrounding at least a portion of a first conduit and at least a portion of a second conduit which extends through said first conduit, said first conduit being intended to communicate with the spa with at least a first orifice in said first member and intended to communicate with the halogen generator through a first port of said wall fitting, and said second conduit being intended to communicate with the spa with at least a second orifice in said first member and intended to communicate with the halogen generator through a second port of said wall fitting.
