Invest in solid technology that grants quality tissue, optimum drying and energy saving.
Explore the Valmet Advantage™ AirCap™.
When investments are strongly driven by the need to be more competitive, improve product quality, while being environmentally responsible, Valmet Advantage AirCap (AAC) is the answer. We offer you our 50-year experience with more than 500 Yankee hoods successfully delivered worldwide, as well as our continuous research and product development.
The construction of the Advantage AirCap is well proven to optimize the distance between the hood and cylinder on the AirCap wrap at all operating temperatures. A controlled thermal expansion also ensures a long life cycle of the equipment, one of the longest in the industry. You can also choose a special construction that allows for operating temperatures up to 700°C.
The graph shows the correlation between gas consumption trend and hood/cylinder distance.
The Advantage AirCap Air system is dimensioned and designed to optimize energy efficiency and reduce emissions to the atmosphere.
On the Advantage Aircap you have a full profiling on the Wet End and additional profiling zones on the Dry End edges to control over- drying. You also have a manual or actuator-remote controlled profiling zones.
The Advantage AirCap has an automatic washing system to remove dust from the hood roof, thus preventing the risk of fires. Not only does it provides you with a healthier and safer working environment, it also reduces downtime needed for cleaning and maintenance.
This can also be integrated with the Dry End Dust Cap washable roof of the Advantage WetDust system
Valmet has developed a new Yankee hood which allows a perfectly even drying profile on one side and the possibility to correct a non-optimal moisture profile on the other. As a result, a better final product quality, with less converting problems and a higher profitability are achieved.
The arrangement of the crescent headers is normally oriented in Machine Direction. In the patented Advantage AirCap Heli the headers are tilted in Cross Direction. Therefore, the average drying intensity transferred to the paper is perfectly uniform in Cross Direction, thus eliminating the hood footprint in any working condition.
The new helical design determines a gradual average impingement speed variation with which the drying paper travels below the hood, as the crescent headers are at an angle and the paper always travels below two adjacent crescent headers.
With the Advantage BalanceControl you have the opportunity to further improve the drying process. Let us explain how:
