Scholz for wood preservation

Autoclaves for the Wood Industry

Wood is one of the most important raw materials of today and the technical methods for the preservation or modification of wood are becoming more and more sophisticated. For this reason SCHOLZ continuously sets new standards in the areas of impregnation, fixation, pressure steaming and heat treatment. Together with our customers, we have the possibility to implement special processes in our company’s own laboratory facilities. 

Successful researches have been made, especially in the area of wood modification. The success is confirmed by the fact that: SCHOLZ has delivered more than 500 units worldwide.


Due to the technical facilities for manufacturing and 70 years of experience in the wood industry, SCHOLZ has become one of the most advanced and dependable suppliers in this segment. Therefore, we can manufacture autoclaves and systems for the most differing requirements such as size, physical load and chemical resistance. The following systems and processes belong to our standard program for the wood industry:


Impregnating vessels

Size, material, design, inspection and approval tests, according to customer-specification.

Pressure impregnation

for pressure impregnation with water-soluble preservatives (also transportable on articulated lorry semi-trailer).

  • naccording to the full-cell and Lowry process
  • according to the oscillating pressure process or for implementation with pulsating pressure for green and moist wood and/or for impregnation with mineral tar oil (Creosote) in accordance with the Rüping empty-cell und full-cell process
  • tilt vessel unit for creosote foot impregnation of poles
  • units for the resin impregnation of wood

Fixation

units for accelerated fixing of water-soluble preservatives in wood (patented special process)


Heat treatment

OHT-units for oil heat treatment of wood


Steaming

pressure steam units for colour modifications of wood, homogenisation of wood colour, improvement of the stress characteristic, dimensional stability, the sorption behaviour as well as hardening properties and glueing ability.


Fabrication

Construction and fabrication according to all European and international regulations


Quality Control System

Application of the most modern production facilities in connection with a proven system for the approval of the equipment through a notified body (e.g. TÜV, Lloyd’s etc.). All necessary tests can be carried out on-site. This guaranties high quality, proven product characteristics at the highest level of safety.



New developments

  • development of unit components at the company’s in-house laboratory facility for the modification of wood (acetylation, furfurylation, PLATO etc.)
  • development of a unit for the oil heat treatment of wood
  • participation in a research project for the pressure steaming of wood

All units can be equipped with our self-produced fully-automatic monitoring and controlling equipment

The autoclaves are available in all transportable diameters and lengths. Autoclaves with a diameter of 3,500 mm and a usable length of 30,000 mm have been built in the past.
