Examples of plants that form part of our business are creosote impregnation plants, SSV vacuum dryers, energy vacuum dryers for construction timber, impregnation plants, heat treatment plants, creosote impregnation plants, fixation plants, double vacuum impregnation plants and hot-oil treatment plants. So far 800 plants in 36 countries have been delivered and are being serviced within the industrial wood preservation industry.

Since 1985 the SSV vacuum dryer has been delivered to 250 customers worldwide for drying of first class hardwood and softwood. A new energy vacuum dryer has been available since 2003. Today these highly recognized vacuum drying plants are in use in almost every field of the wood drying industry. Continuous development is ensured in cooperation with leading institutes as for example the Holzfachschule Biel in Switzerland, BFA in Hamburg, and Forintec in Canada. Examples of recent developments of WTT are the heat treatment plants as well as plants for treatment with hot-oil (linseed oil).
