Systematic modernization

Retrofitting Paper Machines

Paper machines are impressive steel structures. The drive switchgear, which is essential for operating the machines, is also remarkable. Before replacing an old switchgear, operators ask themselves a few questions:

Who can modernize it? How long will the downtime be? Which devices are suitable in the long term?

Our answers – short and sweet:

  • Expertise: We have 35 years of experience in modernizing paper machines, cross cutters, rolling mills, and coating machines. We offer a wide range of services, including drive technology, control systems, guidance systems, network technology, and our own safety department.
  • Downtime: As short as possible thanks to precise planning and an experienced team.
  • Equipment selection: Individual and tailor-made – we provide honest advice and take your preferences into account.

Side Note: Why ABB ACS880 Converters?

While Siemens is represented in many paper mills with SINAMICS converters and the PCS 7 control system, we would like to highlight a few advantages of ABB ACS880 converters at this point. ABB offers complete kits for installation in Rittal standard cabinets. The cabinets are designed so that all devices of a given size fit into the same cabinet – even a later replacement with a more powerful device is possible without any problems. Thanks to the variable width, old cabinets can be replaced 1:1 in the same location, which shortens the conversion time.

The large converters are mounted on casters for mobility and are connected via plug-in connections – installation time: 15 minutes. Smaller sizes are also guided by rails on the sides and do not simply fall out when replaced. DC switches and dU/dt filters are always housed in the same enclosure, and the self-explanatory control panel can be operated intuitively across generations. ABB converters do not necessarily require an ABB controller.

KRIKO has a solution with the KRIKO drive library based on S7, TIA, or PCS 7. We also couple our system with Damatic, ALSPA, or adapt existing controls to ACS880.
