Thermal treatment plant / thermal chamber for modification of wood

The WTT thermal chamber is a system for the thermal modification of wood. It enables efficient processing of 2 to 3 batches per day, depending on wood thickness and species. The system features a high-performance energy and heat transfer system and operates with a gas- or oil-fired boiler, using thermal oil as the heat transfer medium.
