Over the past few years, HERGEN has been supplying many Yankee Cylinders to the national and international markets.
Our manufacturing line has the capacity to build cylinders with diameters up to 7,320 mm (24ft) and with double width (up to 6,500 mm).
Therefore, we can meet almost any need in the paper industry segment, and we are definitely established in the market as the main supplier of Yankee Cylinders in Latin America.

Paper production consumes a lot of energy. In a Tissue paper machine, the drying process is responsible for about 70% of the machine's energy consumption. This means that a more efficient drying system results directly in significant energy savings.
Hergen Smart Yankee Dryer is made of Steel. Due to the mechanical properties of this material, its thickness can be significantly less than the ones made of Cast Iron, increasing the heat transfer by up to 35%, resulting in lower energy consumption for the same production.
NO rupture risk due construction in carbon steel
Increase 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 capscrew or welded to the cylinder shell
Metal surface with high hardness resulting in better creping quality
Excellent temperature profile
Steel plate material allows cylinders construction with any required diameter
Easy transportation: journals may be transported disassembled thus reducing the maximum load height
