First class impregnation of wood in record time

The full-automatic high pressure timber impregnation plant from WTT has been developed with the aim to operate up to 16 hours without supervision. The annual capacity of the full-automatic plants varies from 26,000 m³ to 60,000 m³ of wood.

Durability class insured with minimal work force. The impregnation process insures the wood durability classes 3 and 4 and can be managed by only one operator for 8 hours. The job of the operator contains in just loading and unloading the charging area.

Tilting system. The autoclave is tilted 5 degrees during the process, which facilitates the dripping of superfluous impregnation solvents via grooves and shipways. After exiting the plant through the chain track, the wood packets are tilted transversely at 5 degrees, in order for the solvent to drip off. 

After approx. 16 hours on the chain track the wood is already dried enough to be safely transported to the storage area. All the rest of superfluous impregnation solvent is lead back to the storage tanks by using the steel plate underneath the dripping area.

How does it work? All information about the wood packets (width, thickness, length and volume) is scanned by a bar code reader and automatically sent to the control system, that chooses the impregnation program according to the information sent. When the process is completed, the data regarding the impregnation date and uptake amount (kg/m³) is returned to the bar code.
