Designed to op­timize drying and energy efficiency

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.

Air system that reduces emissions and optimizes energy efficiency

The Advantage AirCap Air system is dimensioned and designed to optimize energy efficiency and reduce emissions to the atmosphere.

  • Natural gas, LPG, steam, diesel oil, dual fuel burners, as well as steam and diathermic oil heated systems
  • Electric heaters – as an alternative to fossile fuels
  • Heat recovery systems for steam generation, combustion and make-up air, room ventilation, fresh and process water for the best utilisation of exhaust air energy
  • Possibility to utilise co-generation (CHP) exhaust gases

 

Effective moisture profile regulation

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.

Washable roof for a better work environment

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

The best drying uniformity and profiling capability with Advantage AirCap Heli

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.

Advantage BalanceControl™ (ABC)

With the Advantage BalanceControl you have the opportunity to further improve the drying process. Let us explain how:

  • It provides optimal and automatic balance control of hood and air system for any production range
  • The system boosts productivity while reducing and ultimately minimising energy consumption
  • Possibility to remote-control and modify parameters on-line, as well as to connect directly to Valmet experts for remote diagnostics on the drying process

Saving potentials

Advantage BalanceControl, burners for alternative fuels, the waste heat steam generator and air to water heat recovery can help you save water, energy and reducing CO2. And therefore lower the environmental footprint in your tissue production. Get in touch with us and we can discuss more in depth what it could mean for your mill.
