This unique thermo treatment plant is designed for heat treatment of 2 to 3 batches per day, depending on thickness and wood species. The plant is therefore equipped with a high performance energy and heat transfer system.
The heat is produced by a gas- or oil-fired boiler that heats thermal oil. The oil is used as heat transfer media in both the heating and cooling phase. In the cooling phase the heat is ejected in a dry cooler.
The product is pressurized in a controlled, oxygen free atmosphere during the heating and cooling phases, and with only a small amount of water steam.
The plant is controlled by the unique WTT ExoT control system which enables an unchallenged degree of control of the modification process.
The plant is the most advanced and most competitive solution on the market today.
