The Dryer has steel heads bolted to its shell resulting in a harmonic assembly with high rigidity and dimensional stability. This new technology obtained by Damapel is operating since 10 June 2010. The PM that received the Yankee Cylinder is a Crescent Former type, also manufactured by Hergen, with a paper widht of 2880 mm and its drying system was upgraded to allow the machine to operate in a speed of 1300 m/min.
