Thermally modified wood is an alternative to the impregnated wood. Improved properties predetermine this material to much more applications than untreated wood, including use in difficult weather conditions or in the interior equipment.

Hightemperature Kilns type KHT

Hightemperature dryers are designed for thermal treatment of tree species at temperatures from 170 to 230 ° C. Due to the hightemperatures used and for reasons of resistance to the wood acids are made in stainless steel design with a hermetically closed inside space during the heat treatment process. The best quality is quaranteed by heavy – duty fans together with efficient fan motors placed outside of the kiln. Heating sources are gas/oil burners, hot oil fluid or option with electric power. The process is controlled by a fully automatic control system. Hightemperature kilns are supplied with rail trucks – wagons for treated material with capacity from 5 to 90 m3 in one load.

Key product properties
  • Massive stainless steel Design
  • Heating source-gas/oil burners, hot oil or electric heating
  • Fully automatic control of the drying process
  • Heavy-duty fans with a very durable propellers
  • Wagons and the floor also in stainless steel
Hightemperature dryers are designed for high stress environment.
Due to the extreme conditions during the process highly resistant components are used for the Design of these kilns.

Thermal modification of timber can permanently improve many properties of wood,
namely biological resistance, dimensional stability, acoustics as well as the equilibrium moisture content reducing, and more. High-temperature treated wood is naturally harmless - just heat and steam is used in the manufacturing process, not any additional chemicals and other ingredients added.

The process effects on wood chemical composition and therefore changes the properties of wood:
  • highly diminished shrinkage and swelling
  • improved dimensional stability
  • improved biological durability against insects
  • improved biological resistance to rot and mould
  • improved surface wearing
  • wood becomes lighter in weight
  • wood colour of changes into warm tone of brown colour uniformly throughout
  • the effect of the appearance of "tropical wood"
  • long-lasting service life
  • because of reduced deformation Hightemperature treated wood is good base for coating
Using a high-temperature treated wood from KATRES kilns:
  • landscaping
  • garden architecture
  • garden furniture
  • building components
  • external door and window components
  • noise barriers
  • shutter
  • wall panelling
  • sauna and bathroom etc.
