New sealing technology from Voith: upgrade for ProRelease+
• Reduced fabric wear thanks to minimized deflection
• Faster production speeds through an optimized vacuum zone
• Greater durability of sealing strips and easier servicing
Voith’s new MultiSeal Plus sealing technology improves processes in the dryer section of paper machines. Thanks to a shorter high-vacuum zone, the fabric deflection is significantly reduced and fabric wear is decreased. In addition, the adjustable SkySeal Plus sealing strips consistently optimize fabric runs and extend maintenance intervals. The entire sealing technology upgrades the web stabilization system ProRelease+ and results in better performance and an increase in machine speed.
The MultiSeal Plus is the carrier system for the SkySeal sealing strips. A key innovation is the horizontal adjustability of the new strips, which can be re-adjusted by up to 12 mm depending on the amount of wear. As a result, the correct distance between fabric and sealing system is guaranteed at all times. The SkySeal is available in two models with different hardness levels, which makes it easier to accommodate the characteristics and requirements of the respective paper machine. As a result the sealing strips suffer less abrasion.
The MultiSeal Plus carrier systems can be adjusted to provide an optimum seal of the release zones in the ProRelease+ sealing systems. Thanks to the new technology, the high-vacuum zone can be shortened overall. This results in an increase in runnability and reduced energy costs. The entire upgrade for ProRelease+ should be suitable for all fast-running paper machines.
