Thermal treatment plant / thermo-chamber for wood modification

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