RENZMANN contribution to Circular Economy
At printing ink manufacturers, gravure printers and flexo printers we can find ink contamination of production vessels, gravure cylinders, anilox rollers and other printing press parts that need to be cleaned after use, very often with combustible solvents. These can be treated in a distillation unit after their use. In the field of flexographic printing, the washing out of clichés is also added as a further process. These solvents are also recycled and then used again.

Our products

Product category: Solvent recovery plants

Distillation unit type ROTOmaX

Distillation unit type ROTOmaX recovers washing solvent and washing fluids and treats ink residues in a cylindrical distillation boiler featuring a steam-heated floor. The unit is designed for batch operation and continuous operation. High-boiling solvents can be distilled with the available vacuum technology. An agitator/scraper system rotating slowly in the boiler permanently stirs the contents, keeps the heating surfaces clean to ensure an optimum heat transfer and, at the end of distillation, automatically discharges the residue through the open discharge valve at the bottom of the boiler. With the type-examined agitator/scraper system and other safety-related details, the unit meets ATEX requirements.
