We design and build Carbon Steel Drying Cylinders for small and large machines, through a modern and rigorous process, within the highest quality standards required by the world market.
The many advantages of carbon steel construction
Carbon Steel, with its ductile nature, allows the use of smaller wall thicknesses in the cylinder liner, resulting in a higher heat transfer rate to the paper sheet.
Six of the 49 former Cast Iron Drying Cylinders were replaced by Hergen Carbon Steel Cylinders
Hergen Cylinders have a smaller difference between the saturated steam temperature and the Cylinder surface temperature, when compared to Cast Iron Cylinders.
Increase in usable width
The more compact construction of steel cylinders increases their usable width, which can solve wet edge problems in drying.
Carbon Steel construction eliminates the risk of explosion.
The covers are welded, eliminating the possibility of leaks.
