Oji Papéis Especiais invests in innovative solution from Voith that allows significant water and energy savings


Voith has a new order to supply its innovative lubrication system for suction roll sealing strips – HydroSeal – to Oji Papéis Especiais. The HydroSeal system prevents sheet rewetting and drastically reduces water consumption.

Operating in Piracicaba, in the state of São Paulo, Brazil, Oji’s specialty paper mill produces nearly 120,000 metric tons of thermal paper, carbonless copy paper and coated paper. The new HydroSeal is expected to operate from mid-September.

Once it is installed, HydroSeal will allow a considerable decrease in water consumption, as well as a performance improvement in the transfer suction roll operating between the second and third press of the Oji PM 2.

HydroSeal is an innovative option that replaces current conventional seals and lubricating showers installed in suction rolls in favor of a more efficient seal system that distributes the lubricant film more evenly over the entire width of the sealing strip. The system hence enables a significant decrease in the amount of water consumed while also minimizing sheet rewetting, which in turn improves the CD moisture profile. This system will allow paper manufacturers to disable conventional shower systems regardless of the suction roll type or manufacturer.

The patented sealing strip system with integrated water supply enables significant savings, and in some cases may also provide for drive power savings. Trials carried out in Germany demonstrate that by using HydroSeal, paper makers can achieve yearly savings of approximately € 100,000, since water and energy consumption can be reduced by up to 87% and 9% respectively.

Since its recent release, nine HydroSeal systems have been sold worldwide, including the one to Oji Papéis Especiais.
