Low pressure/double vacuum impregnation

WTT double vacuum process for impregnation of dimensionally stable components like, e.g. window frames, doors, and garden furniture.
In this plant the timber is preserved with organic wood preservatives (either water emulsion or organic solvent based) in a vacuum/low pressure process for hazard classes1-2.

Through double vacuum impregnation, a basic protection is given to the wood at a fairly low pressure of up to 2 bar.

WTT low pressure plants work with approx. 95% vacuum and a particularly quick filling in order to achieve better control of the absorbed wood preservative agent and to avoid excess uptake of impregnation material in the filling phase.
