WTM-Vaglio - Model APV -Vacuum Pressure Autoclaves

THE WTM VAGLIO TECHNOLOGY: VACUUM AND PRESSURE

The structure of the wood is similar to that of a sponge, with cavities and walls.

The aim of impregnating the wood is to cover the walls of these cavities with the impregnating agent to protect them from decay caused by fungi and insects.

The preservative penetrates deep into the wood thanks to the effect of pressure and vacuum. Initially, the vacuum removes the air from the cavities to create space for the impregnating solution, which is forced deep into the wood by strong pressure (Bethell or "full cell* process).

The excess impregnating solution is then removed from the surface of the wood by a final drying step.

The plants are equipped with a management system that automatically controls all stages of treatment.

At the end of each cycle a report is also generated that records all important data, including absorption (litres o preserving liquid absorbed by the wood), to ensure the traceability of each load and the compliance of the treatments with regulations.

Our pressure systems are designed, built and tested according to the Pressure Equipment Directive (PED).

We offer many optionals to meet the different needs of our customers:

• automated wagon extraction
• automated door
• preparation tank for preservative solutions
• automatic dosing system
• internal painting with epoxy enamels

Our team of engineers and technicians is always ready to study a solution to meet the most diverse requests!
