International technology group Andritz has received an order from Lignatherm AG to supply a pressurized refining system for a new insulation board production plant in Küssnacht am Rigi, Switzerland.
This greenfield plant will use exclusively wood chips from local forests to produce eco-friendly insulation board. The new line, with a capacity of 10 bdmt/h, will comprise a pressurized refining system with a 44-1C(P) single-disc refiner and a pressurized digester with counter flow and steam regulation including a C-feeder at its core. A 14” Andritz plug screw feeder will ensure excellent dewatering leading to improved fiber quality at reduced electrical and thermal energy consumption.

Lignatherm is a subsidiary of Schilliger Holz AG, a company operating sawmills and wood processing plants at three locations in Switzerland and France.
