Renzmann

D.W.RENZMANN Apparatebau GmbH was founded in 1969. They are a medium-sized company that develops, manufactures and sells cleaning and solvent recovery systems for the graphic arts industry and the paint producing industry. In the first industry segment, they are market leader, in the latter segment, one of the world’s leading suppliers. Their equipment can be found on all continents of the world. And their high quality standards have earned them a good reputation in countries around the globe.

On August 1, 2005, D.W. Renzmann Apparatebau GmbH, Monzingen merged with the Swiss Riobeer AG Cleaning Solutions to form the Renzmann Group. With this step, D.W. Renzmann Apparatebau has completed its product portfolio. As a result of this merger, the Renzmann Group is now able to offer its customers a permanently wider range of washing machines and distillation units by one manufacturer. D.W. Renzmann Apparatebau will integrate the Riobeer cleaning systems into its own range of products in order to continue developing, manufacture and sell them. Riobeer AG Cleaning Solutions will focus its activities on providing service and supplying spare parts for the Riobeer systems and machines. In addition, it will support D.W. Renzmann Apparatebau in the sale and planning of Riobeer machines.




List Of Products

Distillation Units - Model ROTO

Distils solvents with a high concentration of solids. The heating surfaces are permanently cleaned by a rotating scraper system, no manual cleaning required. Once the residue has cooled, it is pasty or solid.   Recovers contaminated solvents and washing agents. The distillate is as effective as new solvent. 

Designed for batch operation and continuous operation.  Heating with thermal oil or steam provided by customer or with electrically heated thermal oil. 

Discharge of residue and effective self cleaning of heating surface by scaper system with wiper.  Distillation under vacuum to lower boiling point and heating temperature.  Automatic distillation with low attendance, automatic shut-off when reaching desired densification.

Various options to meet respective task, Ex-proof category ½ according to ATEX.


Distillation Units - Model ROTOmaX

The ROTOmaX recovers washing solvent and washing fluids and treats ink residues in the cylindrical distillation boiler featuring a steam-heated floor. 

The until is designed for batch operation and continuous operation.  High-boiling solvents can be distilled with the available vacuum technology.  An agitator/scaper 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 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.  The only waste remaining is a small quantity of concentrated sludge or solid residue. Reduction of energy costs by means of warm water heating or energy regeneration through condensation of vapor, i.e. the energy contained in the vapor (= vaporized liquid) is used to heat the unit.


Washing Machines - Model 150 – Top Loading

Cleans gravure cylinders with solvent.  Very good cleaning results due to rotation of the gravure cylinders and short spraying distances combined with a powerful washing pump.  The solvent tank is separated from the washing chamber; hence emissions are considerable reduced.

The machine can be adapted to various tasks with the appropriate accessories.  The washing machine is type-examined and explosion-proof in accordance with ATEX.
