The present invention relates to a device for conditioning water containing calcite and an installation constructed with this device. This device essentially comprises an inner tubular element (10), an outer tubular element (11) and two end tips (12 and 13). These elements are arranged so as to provide an annular space (18) between the tubular element (10) and the tubular element (11). The inlet tip (12) comprises a central hole (19) and at least one lateral opening for providing communication of the central hole with the annular space (18). The outlet tip (13) comprises a central hole (21) and at least one lateral opening for receiving the water circulating through the annular space (18). The lateral opening or openings of the inlet tip are arranged so as to develop a helicoidal circulation of the water in the annular space (18) whatever the operating rate may be.

Device for conditioning water containing calcium carbonate by circulating the water along a helicoidal path across a permanent magnetic field, comprising: a first tubular element made of electrically insulating material, an axial stack of permanent magnets in the first tubular element, the magnets being arranged with like poles of adjacent magnets adjacent each other; intercalated blocks in the first tubular element and placed for separating the magnets; a second tubular element arranged coaxially around the first tubular element to define an annular space for circulation of water between the first and the second tubular elements; and inlet and outlet tip elements mounted respectively at both ends of the tubular elements for closing the first tubular element and for holding both tubular elements in their respective relationship, each tip element having an axial bore and having at least one lateral opening providing communication between the axial bore of the tip element and the annular space between the tubular elements; the at least one lateral opening of the inlet tip element comprising a first lateral opening which is directed substantially tangentially with respect to the axial bore and which has a first axis forming an angle of about 90°with the axial direction of the device, and a second lateral opening which is also directed substantially tangentially with respect to the axial bore but which has a second axis that is inclined to form an angle smaller than 90°with the axial direction of the device, wherein respective projections of the first and second axes in a plane perpendicular to the axial direction of the device form with each other an angle in the range from 60°to 80°, and whereby the angles of the first and the second lateral openings generate a helicoidal path of water flowing in the annular space. Installation for conditioning water containing calcium carbonate by circulating the water along a helicoidal path across a permanent magnetic field, comprising: a first tubular element made of electrically insulating material, an axial stack of permanent magnets in the first tubular element, the magnets being arranged with like poles of adjacent magnets adjacent each other; intercalated blocks in the first tubular element and placed for separating the magnets; a second tubular element arranged coaxially around the first tubular element to define an annular space for circulation of water between the first and the second tubular elements; an inlet and an outlet tip mounted respectively at both ends of the tubular elements for closing the first tubular elements and for holding both tubular elements in their respective relationship, each tip having an axial bore and having at least one lateral opening providing communication between the axial bore and the annular space; and two parallel helical walls defining first and second helical channels in the annular space between the inlet tip and the outlet tip, the second helical channel having a larger cross-section than the first helical channel; wherein the outlet tip comprises a shutter which is movable by a predetermined water pressure in the annular space from a closing position wherein the outlet tip axial bore communicates with the first helical channel but not with the second one, to an opening position wherein the axial bore communicates with both helical channels.
