Wood fibre insulation board manufacturer Gutex has produced their first fibres with their new Andritz fibre preparation system in Eschbach, Germany.

According to Andritz, this is the second system they have delivered to Gutex.

Oliver Bauch, plant manager, Gutex, said: “The new line will perfectly support the environmentally friendly production approach for our ecological insulation board products. Thanks to the excellent cooperation and the great effort of the whole Andritz team we were able to produce first fibres even ahead of schedule.”

Michael Rupp, vice-president for Panelboard Systems, Andritz, added: “We are proud that Gutex again chose to collaborate with us and that we had the opportunity to provide them with our complete front-end technology.”

The scope of supply comprised a complete fibre preparation line, including a debarking and chipping line as well as the steel structure, piping material and installation work.

The system processes softwood chips as raw material, and features the following technological highlights:

The Andritz RotaBarker debarking system and horizontally fed HHQ-Chipper for consistently good chip quality at high production rates; a fully automatic chip storage system with reclaiming and screening equipment; a high-consistency pressurised refining system to obtain high fibre quality and low specific energy consumption; and the Steam Recovery System (SRS) for efficient recovery of surplus steam and greater thermal efficiency of the fibre preparation system.

Gutex is a family business based in the German Black Forest, and started making wood fibre insulation products back in 1932.

In 2006, Gutex was the what was said to be the “first company” to start producing wood fibreboard insulation with a homogeneous raw density profile using an innovative drying process.

This technique allowed Gutex to manufacture single-layer wood fibre insulation board up to 240mm thickness.
