Varberg Timber
Upgrade of Fully Automated Impregnation Plant
Customer: Varberg Timber
Location: Varberg, Sweden
Upgrade period: 2025–2026
Plant category: CCA Impregnation
The Challenge
Varberg Timber wanted to upgrade and future-proof its existing fully automated impregnation plant and transport system. A key part of the project was to replace the existing autoclave with a pre-owned stainless-steel autoclave purchased by Varberg Timber from another sawmill.
At the same time, several mechanical components of the plant and transport system required upgrading to improve operational reliability and ensure the installation could continue to meet the demands of daily production.
The Solution
WTT carried out the complete upgrade and recommissioning of the fully automated impregnation plant and transport system.
The existing autoclave was replaced with the pre-owned stainless-steel autoclave. As part of the installation, the internal rails were replaced, new hydraulic clamps were installed, and the autoclave was pressure-tested to verify its condition and ensure compliance with applicable requirements.
The rail system for the automatic traverser was also upgraded with an adjustable design, following the same principle used in WTT’s new fully automated plants. This allows for precise alignment of the rails and significantly improves the reliability and operation of the automatic transport system.
Following installation, the complete system was tested and recommissioned by WTT.
The Benefits
With the upgrade, Varberg Timber gained:
A refurbished and future-ready fully automated impregnation plant
A stainless-steel autoclave integrated into the existing production system
New internal autoclave rails and timber hold-down systems
An upgraded adjustable rail system for improved transport reliability
Pressure testing and verification of the autoclave
Improved operational reliability and reduced risk of unplanned downtime
Continued WTT service and preventive maintenance through a service agreement
The Result
Varberg Timber now has a modernized and future-ready impregnation plant, combining existing equipment with carefully selected upgrades to extend the lifetime of the installation and improve day-to-day operational reliability.
Following the upgrade, Varberg Timber has also entered into a service agreement with WTT, allowing us to provide preventive maintenance and ongoing technical support with the objective of achieving the highest possible plant availability and uptime.
