The new Ribbed Steel Yankee Dryer produced by Hergen was designed with the best manufacture techniques and concepts thus giving to this equipment a high operational security and dryness efficiency. The dryer's shell is manufactured in high mechanical resistant steel plates and receives a metal coating applied by an Arc Spray process resulting in a surface with excellent hardness and final roundness controlled to suite the creping conditions.
At Damapel Com. e Distr. de Papéis Ltda., company located in the city of Guarulhos, State of São Paulo, Brazil, the Yankee Cylinder supplied by Hergen was designed for a working speed up to 1500 m/min and maximum working pressure of 10,5 bar with a maximum nip load of 120 kN/m. 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.
