Steel Yankee

With diameters up to 22 ft. and shell lengths up to 7.4 m, ANDRITZ is the technology leader for large steel Yankees. These high performance drying cylinders are made entirely of steel, resulting in greater safety and better machine performance than cast Yankees. Of the 50 ANDRITZ PrimeDry Steel Yankees already sold, 13 are in the large size range (> 18 ft. diam. and > 6 m shell length), amongst them the world’s largest steel Yankee in operation for tissue.


The performance of an ANDRITZ PrimeDry Steel Yankee exceeds the performance of a cast iron Yankee of the same size. Steel Yankees have an evaporation rate that is 10-15% higher than that of cast iron models, which results in 8-10% better machine performance.

Head insulation

Tissue machine Yankees often show significant heat losses at the head. The savings in steam using head insulation is in the range of 2-5%. The head insulation is not only for new Yankees, but can also be retrofitted to existing units.
