Characteristics of the treatment:

The application is done on wood of any essence through a cycle that includes vacuum phases and phases of pressure forced into the autoclave.
The timber is stowed on trolleys and inserted into a large cylindrical tank airtight. Here, under close supervision, is subjected to the following processing steps:

  • Period of depression of about 1 hour at a pressure of -1.0 Bar,
  • Injection of the exclusive mixture Tanalith: ecological solution which is introduced into the wood through a pressure which reaches 16 bar for the duration of about 3 hours (depends on the type of wood to be treated).
  • Period of depression of about 1 hour at a pressure of -1 Bar with the aim to eliminate the excess of liquid in the timber.
  • At the end of the cycle, the timber is dried, preferably outdoor, if there are times, or by forced drying controlled.
  • The treatment follows a strict operative protocol and is guaranteed by scrupulous periodic checks by the TÜV SÜD. We can obtain the pattern and a summary of data related to each cycle of impregnation.
