  • Patent number: 7696490
    Abstract: A device for the UV treatment of fluids flowing in a flow channel, including a plurality of cylindrical low-pressure mercury UV emitters arranged in groups in the flow channel. The longitudinal axes of the UV emitters are disposed substantially parallel to one another such that the emitters of a given group are disposed in a plane. At least one elongated sensor arrangement monitors the operating state of the emitters, and is spaced from and parallel to one of the groups of the emitters. The sensor arrangement extends essentially transverse to the longitudinal axes of the emitters of the adjacent group, and is provided with a separate UV sensor for each emitter. At least one unit connected with the sensor arrangement controls and/or regulates the emitters.

  • Patent number: 7427763
    Abstract: A method of operating a UV disinfection device provided with at least one UV emitter, including supplying the emitter with an operating voltage for a firing and continuous operation thereof, modulating the operating voltage, an operating current, or an electrical power of the UV emitter, detecting the UV radiation emitted by the emitter with a UV sensor that is adapted to temporally resolve the modulation, evaluating the signal recorded by the UV sensor, and checking whether the modulation in the signal given off by the sensor corresponds to a desired value.

  • Patent number: 7061173
    Abstract: A UV lamp unit is provided and comprises a lamp in the form of a mercury low pressure amalgam lamp that is provided with at least one amalgam deposit. A cladding tube surrounds the lamp in such a way that an air gap is provided between the lamp and the cladding tube. An element is provided in one axial direction of the lamp, in the region of the at least one amalgam deposit, for influencing the temperature of the amalgam.

  • Patent number: 6906468
    Abstract: The invention relates to a novel ballast device for pre-heating, starting and operating at least one UV emitter, constructed in the form of a gas discharge lamp with two heating coils lying opposite each other in relation to a gas discharge path, whereby four electrical connections are provided in total for each of such gas discharge paths, namely two for each heating coil. According to the invention, switching means are provided for a parallel switching of both of said connectors of a heating coil, dependent upon operating conditions. A capacitive loading of the ballast device is thus avoided by means of the otherwise open connector line for the heating coil and the current feed to the coils is evenly distributed.

  • Publication number: 20030057868
    Abstract: The invention relates to a method and a ballast for feeding a UV light low pressure radiator. The UV light low pressure radiator is ignited and subsequently fed with direct current. The polarity of the direct current is changed at successive intervals which are greater than half the period of the conventional network frequency and smaller than a time until a lower threshold value for the operational temperature of the electrodes is reached, whereby said time is a result of the thermal time constant of the UV light low pressure radiator.
