Yankee Dryers
The quality of the Smart Yankee Dryer fabricated by HERGEN is attested by the many cylinders supplied to the tissue market in Brazil and abroad.
These cylinders are fabricated in carbon steel and feature ribbed internal surface, characteristics that allow higher heat transfer and therefore higher drying efficiency.

Cylinders advantages
NO rupture risk due construction in carbon steel
Increased production: : HIGHER HEAT TRANSFER UP TO 35% AS COMPARED WITH CAST IRON CYLINDERS resulting in higher paper evaporation ratio
Innovative condensate extraction system
Higher reliability with no risk inherent to the casting process, such as porosities or discontinuities
Two construction options for Head Covers: mounted with cap-screw or welded to the cylinder shell
Metal surface with high hardness resulting in better creping quality
Excellent temperature profile
