Vacuum-Drying Plant
Fast, Gentle, and Environmentally Friendly Drying
Pioneers in Vacuum-Drying Technology
WTT revolutionized the wood drying industry in the late 1970s with the invention of modern vacuum drying. Since then, we’ve delivered over 250 vacuum-drying plants worldwide, and the technology continues to lead the way in performance, quality, and sustainability.
Our vacuum-drying (VD) technology offers three key advantages over traditional kiln drying – making it the preferred choice in industries where speed, color preservation, and environmental responsibility are paramount.
Why Choose WTT Vacuum-Drying?
Up to 5x Faster Drying – With Lower Energy Use
Vacuum drying works 3 to 5 times faster than conventional kilns and uses significantly less energy. This makes it ideal for meeting tight deadlines and shifting production demands – without compromising on quality.
Natural Color Retention
Traditional drying often darkens the wood. WTT’s vacuum process maintains the wood’s natural color – for example, beech stays bright and white – a growing advantage as market preferences shift toward lighter wood tones.
Sustainable and Clean Process
Vacuum drying is a closed system. While traditional kilns can emit 1,000–5,000 metric tons of VOCs annually, our system captures most volatile compounds like turpentine in the condensate. As environmental regulations tighten, this technology becomes an even more competitive and responsible choice.
