Modernization of existing plants: Product information

    VEM transresch are specialists when it comes to modernizing existing converter equipment.

    Where is modernization of interest?

    Modernization of existing DC drives is worth thinking of in all applications where complex medium-power and high-power analogue converters are being used, for example in rolling mills and cement plants, in paper-making machines, excavators and other installations.

    What will be part of the modernization?

    The extent of modernization will depend on the state of the existing equipment.

    • The old data and control electronics, including its hardware interface with the power circuit components will be replaced by high-grade digital data and control electronics using various bus systems for communication with the automation level.
    • Replacement of auxiliaries.
    • Replacement of power circuit components, if necessary.
    • Existing DC motors can also be included in the modernization project (examination and overhauling or alternatively supply of new DC motors).

    What will be customer’s benefits?

    • Short downtimes of the installation during reequipment.
    • Specific process requirements can be met.
    • Considerable cost reduction due to reusing high-cost parts of the euipment, such as cables, circuit breakers, transformers and, possibly, power circuit components.
