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.


HERGEN has just delivered two more

Yankee Dryers


Our Yankee Dryers manufacturing line presents the capability to produce cylinders with diameters up to 7.320 mm (24 ft) and face length up to 6.500 mm.

We are accredited to supply drying cylinders and pressure vessels that comply with the main international standards, such as ASME, PED and CUTR032 (Russia).

Therefore, we are now able to attend to any demand from this paper industry segment and definitely have established ourselves in the market as the major supplier of steel Yankee cylinders in Latin America.


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
