Abstract: A magnetic water conditioner having a plurality of permanent magnet cores therein wherein each of the cores is shielded by an individual collector sleeve so that the magnetic lines of force produced by the respective magnets are isolated from each other. This results in the lines of force intersecting the water flowing through the treatment chambers in a more radial direction so as to treat the water more effectively. The unit is easily disassemblable and is adapted to have a plurality of empty sleeves mounted therein so as to bypass around the magnets a portion of the water flowing through the device.

Abstract: A device for the magnetic treatment of liquids, particularly water, wherein a bypass chamber is provided so that only a portion of the liquid passing through the conditioner is subjected to the magnetic field. The device comprises one or more elongated magnetic cores each having an elongated magnet encased within a tubular inner casing of non-magnetic material. The magnetic core is received within an elongated intermediate casing of magnetic material, such as an iron or steel galvanized pipe, and being radially spaced therefrom so as to form a generally annular treatment chamber having an inlet at one end and an outlet at the opposite end. The intermediate casing, since it is formed of a magnetic material, provides a return path for the magnetic field produced by the magnet to confine the magnetic field substantially to the treatment chamber.
