ANDRITZ FiberPulse

Advanced chip treatment - maximum performance

Unlock higher efficiency, lower energy consumption, and advanced pulp quality with FiberPulse, the innovative and patented pre‑treatment upgrade for all compression devices. Designed for Plug Screw Feeders, Chip Presses, and MSD Impressafiners, FiberPulse revolutionizes how chips are prepared for impregnation and lowest energy refining.

Transformative chip conditioning
FiberPulse increases the chips’ surface area through controlled maceration and delamination — enabling more efficient chemical penetration and faster heat transfer.

Significant energy reduction
By optimizing chip structure and reduced moisture content, FiberPulse cuts energy consumption by up to 70 kWh/t, unlocking major cost savings.

Superior impregnation performance
FiberPulse maximizes liquor uptake, enhancing chemical efficiency and reducing the amount of chemicals required — in some cases by up to 40%.

 

Significant steam reduction
FiberPulse ensures fastest heat transfer to the wood and significantly reduces the thermal energy consumption in the pre-heater (digester). 

 

Compatible with all major compression devices

Regardless of the OEM or setup, FiberPulse can be integrated into:

  • Plug Screw Feeders
  • MSD Impressafiners
  • Chip Presses

Upgrades can include new discharge ends, FiberPulse spools, shaft modifications, kicker flights, and optimized housings.

Improved end-product quality

  • Lower shive content (up to –50%)
  • Higher brightness (up to +10%)
  • Better fiber development thanks to highly pre-macerated chips

Cleaner process, fewer deposits
The high compression area reduces extractives and moisture increased the initial brightness and reduced the bleaching effort.

Extended equipment lifetime
FiberPulse upgrades reduce wear, resulting in twice the typical component lifetime, with maintenance-friendly, exchangeable high wear resistant spare parts.
