Autoclaves APCS: The Work Process

  • Initial situation: The opened APCS autoclave cover suspended from a hoist and which in turn is suspended from the load gabion with the material to be treated. Loose parts may be placed in the gabion holders or on pallets for their impregnation.

  • The APCS autoclave is filled with liquid up to the level set by the immersed volumes in the preceding loads.

  • The dual pipe hoist lifts the set that is the cover and the load gabion, and transfers it from the loading/unloading position and immerses it into the APCS autoclave resting the cover over the integrated elastic gasket.

  • The liquid level is adjusted from the appropriate point automatically, by decanting the liquid required to obtain the maximum level and so to commence with the extraction of air from the APCS autoclave and then starting the extraction of the internal air from the wood.

  • The amount of the impregnating product to be injected is calculated by the APCS autoclave program based on the data provided by the work order, depending on product type, intended treatment, wood species and its parameters, through a computer process.

  • On the basis of the processed data the atmospheric air inlet opens and upon reaching the sufficient quantity of supplied impregnating product, the cover opens and the extraction of the treated material takes place.

  • The processed material, applying our prior vacuum immersion technology, not only the application of overpressures is not required, but also allows one to sidestep the excess product recovery cycle, always necessary in the vacuum-pressure-vacuum method, seeing that the wood treated with our procedure does not "ooze out" once treated, all of which significantly shortens the carrying out of the impregnation process with a very substantial decrease in manufacturing costs.
