Three Yankee safety solutions, one trusted partner
Improve safety and ensure stable, efficient operations with Yankee dryer inspections designed to identify potential risks early. We offer three proven solutions:
- Annual inspections to detect cracks, corrosion, steam leaks, and valve issues.
- Fitness for service every 10 years to validate structural integrity and overall condition.
- Non‑routine inspections tailored to your needs, including ultrasonic, material, and Infinikote testing.
Improving Yankee surface finish for enhanced performance
The condition of the Yankee surface is critical to tissue quality and stable production. Even minor surface defects can impact the paper web, leading to breaks, quality issues, and lost efficiency. Regular surface restoration helps maintain optimal performance, extend dryer lifetime, and delay the need for full grinding.
Valmet offers advanced solutions to restore a smooth, high‑performance Yankee surface:
- Yankee surface polishing – removes buildup and chatter marks to improve sheet quality
- On-site Yankee profile grinding – restores surface geometry and running stability
- Thermal coating – protects the surface, ensuring long-term performance and extended dryer life
Smarter energy use at the Yankee
The most effective way to save energy is to reduce demand—and recover what’s left behind. Valmet’s optimized Yankee head insulation and hood and air systems help lower overall energy demand, while smart heat recovery solutions, including waste heat steam generation, turn unavoidable losses into valuable energy. The result is lower operating costs, improved sustainability, and more efficient tissue production.
Yankee metallization for stable performance
Valmet Infinikote‑2 Yankee metallization is applied on a newly ground Yankee surface to create a durable, uniform metallized layer that improves sheet adhesion, supports ceramic doctor blades, and extends Yankee lifetime. The layer is typically about 0.5-1.5 mm thick after application and final grinding. The solution is 100% chrome‑free, enabling stable operation, high tissue quality, and environmentally responsible performance
Valmet Infinikote Yankee Metallizing is the most successful thermal sprayed coating for Yankee cylinders in existence with more than 500 references globally on both cast iron and steel Yankee cylinders
