Reconstructing, modernizing, upgrading and generally overhauling of NIEHOFF-machinery.

Machines made by NIEHOFF are renowned for high quality, top
performance, long lifetime and durability by the expert industries.
Therefore, our machines have always been well worth being overhauled and
put to a state-of-the-art condition by our NIEHOFF specialists even
after many years of operation.

NIEHOFF offers the following reconditioning measures:

  1. Changeover from S5 to S7-1500 control for all machine types
    (optionally upgrading all drives to modern AC technology, bearing up to
    15% energy-saving potential).
    Sudden failure of S5 controllers and modules bears considerable risks
    for production and may cause machine downtime’s. S5 components are no
    longer produced and cannot be delivered any longer.
  2. Mechanical overhaul of almost all machine types such as MMH and M85
    Mechanical overhaul includes replacement of all bearings, sealing
    flanges, labyrinth seals and all other required small parts, thus
    minimizing the risk of unexpected machine standstills and production
  3. Upgrade of the annealing controller
    SIVOLT A three-phase annealer controllers are no longer deliverable.
    Unexpected failure of the controller may cause machine standstill and
    imply high costs due to defective production. We, therefore, recommend
    to upgrade the annealing controller to type NAC developed by NIEHOFF.
  4. Modernizing the control panel
    Legacy operating panels such as PCS900 or LAUER are not delivered any
    longer. As a durable replacement, we offer to upgrade the control panel
    e.g. to type TP 1500 or TP 700. The solution will individually be
    adapted depending on the machine type.
  5. Replacement of the discontinued SIEMENS VC and MC drives
    We offer to convert all Siemens drives, be it VC or MC, to Sinamics
    systems installed either on site or delivered and integrated in form of
    a new switchboard cabinet.
  6. Replacement of discontinued Lenze drives
    Drives of the 8200 and 9300 series may be replaced by 8400 series
    drives. In most cases the operating software must not necessarily be
  7. Inspection and maintenance contract
    Service life of NIEHOFF machines is subject to adherence to the
    inspection and maintenance measures recommended by NIEHOFF, including
    regular servicing intervals and timely overhauls. This will guarantee
    full performance throughout the planned machine life.
  8. A sustainable approach

    With its spectrum of modernization measures, NIEHOFF renders maximum
    support to their customers contributing to energy savings and material
    efficiency in the production processes, with the customers benefiting
    from NIEHOFF’s efforts towards sustainability at the same time.
