Thermal treatment system / thermal chamber for the modification of wood

The WTT thermal chamber is a system for the thermal modification of wood. It enables efficient treatment of 2 to 3 batches per day, depending on the thickness and type of wood. The system has a powerful energy and heat transfer system and works with a gas or oil-fired boiler system that uses thermal oil as a heat transfer medium.
