Impregnation with chromium-free salts
For the impregnation of wood, we focus on top quality for product & process.
Since 2023, the production and sale of wood posts/fences impregnated with tar oil/creosote has been banned throughout the EU. Peter Müller developed an environmentally friendly alternative to produce resistant and durable wooden posts for horse fences.
Pressure impregnation for comprehensive impregnation
Impregnation with non-contaminating, chromium-free salts protects wood against fungus, mildew and insects without damaging the environment. Impregnation is characterised by the light-green colour of the treated wood.
Salt-impregnated wood is ideal for all applications where humans come into contact with the wood.
Peter Müller impregnation cycle for class 4 wood
- Vacuum: The air is extracted from the boiler. The vacuum causes the pores in the wood to open. The impregnation agent is then sucked into the boiler.
- Pressure process: The agent is pressed into the wood.
- Final vacuum: The agent is let out and the wood can drain.
- The wood is removed from the boiler and dries for a day indoors. The product is fixed into the wood.
The fixing time can be reduced to 2-3 hours thanks to our hot-steam fast-fixing chamber.
ATG impregnation certificate
On request we can provide you with an ATG impregnation certificate. The certificate is useful for sawmills that, for example, have to deliver to a building site. Architects and housebuilders very often only accept impregnated wood that is certified.
