There are lots of possible configurations, and our teams will be able to advise the most suitable high pressure wood treatment plant for you, according to your needs and budget.

Plants can be designed for any of the processes required by the timber impregnation industry: –

• Bethel (full cell) – this is the most  common for treatment of timber to Use Class 3 and 4
• Rueping (empty cell) – this process cycle is used for more  specialist lumber  treatments, such as creosote and copper oil, where the impregnation rate needs to be reduced on highly absorbent wood species
• Lowry
• Special cycles using any combination of vacuum, air pressure & fluid pressure phases, which can be designed on request

WHEN TO USE HIGH PRESSURE IMPREGNATION

High pressure treatment is widely used whenever deep impregnation of wood by a preservative required: –

• Sawn or round posts using water based copper chemicals (UC3 / UC4)
• Poles, sleepers, posts using creosote or some of the newer chemicals that are replacing creosote (copper oils)
• Construction timber with fire retardant chemical
• For specific applications, such as resin or furfural impregnation before curing
