Impregnation plant

Classical method

Pressure treatment by chromated copper arsenate (CCA) is by far the most widely used method for wood protection
Disadvantage: CCA treated wood is banned or to be phased out in most countries due to environmental reasons

A superior Supercritical CO2 Wood Treatment Process has been developed by FLS (Denmark) and a commercial plant was set up in cooperation with NATEX:

  • CO2 instead of an organic solvent
  • use of organic fungicides (Tebukonazole, Propikonazole)
  • much shorter impregnation time 
  • no drop-off or evaporation
  • no change in the wood or in moisture content
