🚧 Our Largest Diameter Autoclave to Date Has Left the Workshop 🚧
A big milestone for the team—our largest diameter autoclave we’ve ever manufactured has officially left the workshop and is on its way to site for IMPREGNA/ Rundvirke Poles AB.
This unit is a Ø3.2m x 22.0m high-pressure treatment autoclave, designed for demanding wood impregnation processes using Bethell & Lowry processes. Specifically engineered for the treatment of poles and sleepers, it’s built to handle large-scale industrial requirements.
From heavy-duty fabrication to precision engineering, this project has been a real team effort—showcasing the skill, experience, and attention to detail across the business.
Key highlights:
▪️ 22-metre length with a 179m³ capacity
▪️ Manufactured from 20mm thick steel
▪️ Designed for pressures from -1barg up to +14barg
▪️ Fully integrated hydraulic door system
Seeing projects of this scale leave the workshop is always a proud moment. Now onto installation and commissioning.
