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 downtimes. 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 shortfalls.

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. Integration of our patented magnetic locking device in our WF down coilers 


We can offer this reconstruction measure for our WF 651 and WF 801 coilers for the time being. For the WF 650 and WF 800 coilers the conversion kit will be available at the end of 2020. The new system minimizes the risk of breakdown of the WF coiler and is 100% maintenance-free, thus bearing the advantage of saving spare and wear parts costs required for the formerly used system (gear pair with modified center distance).

6. 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.

7. 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 adapted.

8. Reorganizing wire movement in our RM annealers by integration of ‘fluidic muscles’ 


Considerable improvement has been made in avoiding poor wire movement. The new solution is less susceptible to failures, at the same time increasing process reliability to a great extent. Thorough wire movement is substantial for longer life of the contact tubes.

9. 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.

10. Relocation service for NIEHOFF machinery

We recommend to use our professional NIEHOFF service for any kind of relocation/transfer of NIEHOFF machinery at your plant. In doing so, you can be 100 % sure to eliminate the high risk of considerable machine damage being caused by improper transport or inaccurate installation.
