SVW treatment facilities
High Pressure Treatment 1
Timber loaded into treatment vessel. Initial vacuum applied and the timber cells are evacuated of air. Vacuum held.
High Pressure Treatment Process 2
Cylinder flooded under vacuum with TANALITH wood preservative with TANATONE brown colourant if required.
High Pressure Treatment 3
Hydraulic pressure applied, forcing the preservative deep into the structure of the timber.
High Pressure Treatment 4
Final vacuum extracts excess preservative solution, which is pumped back to storage.
High Pressure Treatment 5
Low pressure inside timber draws in surface solution when vented to atmosphere. Treated timber is left to dry.
