Voith is supplementing its proven Pluralis family with new Pluralis Hot Stock (HS) refiner fillings. Representing a significant advancement in refining technology, they are specifically designed to meet the demanding requirements of pulp mills and to minimize resource consumption. In addition, Pluralis HS refiner fillings can significantly improve paper quality, energy efficiency and overall pulp mill performance.

  • The latest solution in refining offers significant energy and raw material savings for pulp mills and hence promotes sustainability
  • Designed for high shive reduction and improved throughput
  • The use of an STT alloy provides increased abrasion resistance and longer service life

“The new Pluralis Hot Stock refiner fillings combine the high efficiency of the leading Pluralis technology with ideal shive reduction,” says Elias Fleschhut, Global Product Manager at Voith Paper. “Offering impressive shive reduction of 75 to 90 percent, HS fillings significantly increase fiber yield and reduce energy consumption.”

Designed for long service life and highest production throughput
The use of STT alloy provides increased abrasion resistance and longer service life, even under the harsh conditions of a pulp mill with operating temperatures above 90 °C and high throughput requirements. The arrangement of the bars in a non-parallel orientation ensures that the edges intersect at an optimal angle and treat the largest possible percentage of fibers. The design was developed specifically for high kappa pulps and offers the highest production throughput and high shive reduction with extended service life.
