Innovative heat treatment solution for wood
WTT is currently introducing a second generation heat treatment solution, which brings treatment cost down to levels comparable with traditional biocide impregnation.
WTT developed and supplied its first thermo-treatment (TMT) plant in 2005. Two broad technologies for TMT exist, the so called open and closed system approaches. Open systems are essentially advanced traditional drying kilns which are simple and easy to manufacture. Therefore there are numerous suppliers of these types of kilns and increasing price competition between suppliers. The system modifies the timber by a pyrolysis process at high temperatures and normal atmospheric pressure.
WTT’s technology is based on the closed system approach. This system modifies timber by a hydrolysis process at high pressures but lower temperatures, so that pressure acts as a substitute for temperature. It requires advanced design and manufacturing capabilities. WTT is the only company which has successfully marketed the system on a commercial scale and so this technology faces very little competition.
WTT very recently developed a new generation of TMT which has improved its competitiveness significantly.
