International technology Group ANDRITZ has successfully installed a new Multi Motor Drive (MMD) and drive control system for paper machine 3 at Hamburger Containerboard Group’s mill in Pitten, Austria (hamburger-containerboard.com), completing this demanding retrofit project within a very short time.
The installation and start-up of the ANDRITZ scope took less than two weeks.
As part of the upgrade, which aimed to increase operating efficiency and ensure spare parts availability, ANDRITZ replaced the existing DC drive system with a state-of-the-art AC drive system. To meet the customer’s tight schedule, ANDRITZ developed a concept using high-dynamic performance motors with approximately the same frame sizes as the existing ones, which reduced the need for mechanical modifications, adjustments to foundations and downtime to a minimum.
ANDRITZ’s scope of supply included the delivery of all motors, the Multi Motor Drive cabinets consisting of IGBT supply units and inverter units, as well as a tailor-made automation and safety system, all fully integrated into the mill-wide Distributed Control System. Installation services, commissioning, start-up, and subsequent optimization were also performed by ANDRITZ.
“Automation retrofit projects in our industry are often highly complex. So, it is useful to have a partner like ANDRITZ who has comprehensive process and technology know-how,” says Josef Krenn, Managing Director of Hamburger Containerboard, Austria. “ANDRITZ fully understood our challenges and handled them very well. Start-up went smoothly, and our PM3 is running to our full satisfaction.”
