Cast Iron Dryers
Heavy-duty cast iron drying cylinders for long service life and consistent heat transfer.
Heavy-duty cast iron drying cylinders for long service life and consistent heat transfer.
Cast iron dryer cylinders represent proven technology that has served the paper industry for generations, delivering reliable thermal performance through the inherent material properties of quality alloy castings. Parason's cast iron dryers combine traditional manufacturing excellence with modern engineering practices.
The thermal characteristics of cast iron—with conductivity of 45-55 W/m·K—provide good heat transfer from steam to paper surface. The substantial shell thickness of 25-35mm provides mechanical strength for safe operation at rated pressures.
Our cast iron dryers incorporate optimized condensate removal systems with quality alloy compositions and precision manufacturing ensuring uniform heat transfer across the cylinder face.
