Toscotec Launches Breakthrough in Steel Yankee Dryers for Sustainable Papermaking

Toscotec, the global market leader of Steel Yankee Dryers, introduces TT Induction SYD, a carbonreduction breakthrough that redefines Yankee dryer technology entirely. TT Induction SYD uses electrical induction instead of steam energy to dry the paper web, thereby cutting direct greenhouse gas emissions to zero.
In 2000, Toscotec pioneered a major technological innovation, TT SYD, the first Yankee dryer entirely made of steel. Steel Yankees have since surpassed their cast-iron equivalent to become the benchmark for drying efficiency and safety in the paper industry. TT Induction SYD is now set to be the new game changer in tissue for its capability to use clean energy and slash direct carbon emissions associated with the drying process.
A disruptive innovation for dry crepe and TAD tissue machines
With TT Induction SYD, the internal steam distribution and steam/condensate removal systems are entirely replaced by an induction system composed of static coils installed inside the shell and electrical controls and instrumentation located outside for easy maintenance and monitoring. As a result of precise coil geometry, the induction system delivers a very fast and accurate heating effect exactly on the areas of the shell where it is required, while preventing residual circulating currents in other areas.
Steam-heated Yankees use steam energy typically generated by burning fossil fuels. TT Induction SYD uses electrical energy that can be derived from renewable energy sources while delivering the same result, i.e. uniformly heating up the Yankee’s shell in contact with the paper web to achieve dryness. TT Induction SYD is suitable for installation on dry crepe as well as Through-Air-Drying (TAD) tissue lines.
Luca Ghelli, Toscotec R&D Director, says, “Sustainability is the guiding idea of TT Induction SYD’s design. As a proven industrial technology, an induction system offers multiple advantages when applied to the most energy-intensive section of the tissue machine. The efficiency of this cuttingedge technology will dramatically reduce the carbon footprint of papermaking. Based on our expertise in steam-heated TT SYD and induction systems, we succeeded in developing a more efficient and sustainable steel Yankee dryer.”
