Safety concept D.W. RENZMANN Apparatebau GmbH Requirements for distillation equipment Explosion protection of the vacuum unit D.W.RENZMANN Apparatebau GmbH has been developing, manufacturing and selling cleaning and treatment systems for print shops and for paint and varnish producers for nearly 50 years. RENZMANN develops modern distillation processes and technologies that comply with today’s increasingly restrictive environmental and occupational safety regulations and reflect the aim of sustainable environmental protection. The vacuum unit extracts the explosive atmosphere above the...

Cylindrical, vacuum-tight distillation boiler consisting of an insulated dome (stainless steel) with a heating floor (standard steel) flanged to the bottom I nsulated, flat heating floor for heating with steam (10 bars, 185°C max.), consisting of a double-walled plate; the floor ensures an excellent heat transfer and full heating capacity regardless of the solvent level in the boiler Steam generator flanged to the heating floor, operated with electric power or with steam or thermal oil from an on-site network. Direct heating of the floor with steam or warm water is also possible...

Cylindrical, vacuum-tight distillation boiler consisting of an insulated dome (stainless steel) with a heating floor (standard steel) flanged to the bottom Batch distillation or continuous distillation Distillation unit The discharge height is adapted to the disposal container and/or a 200-l-barrel (on a pallet). Other heights are possible A viewing glass and an explosion-proof halogen lamp permit operators to observe the distillation process via mirrors ** water from a public system is used; depends on the water temperature and the boiling point of the solvent; If a closed cooling circuit...

Model ROTOmaX-W High-efficiency distillation unit (15-30 kW, 95% recovery rate) Powerful vacuum pump Two 1000-liter-containers for clean and used solvent Integrated drip pan All components and the entire unit are ATEX-certified The unit can be installed in an area that is not protected against explosions Avoiding waste water in cleaning processes The ROTOmaX-W distillation unit vaporizes soiled aqueous/alkaline washing and rinsing agents. The condensed clean distillate is admitted back into the rinsing water / washing agent circuit of the cleaning process. There is no waste water. The...

A1 Debinding chamber Once the workpieces (green compacts) have been loaded into the debinding chamber A1, the dry and solvent-free atmosphere of the chamber is evacuated and replaced with the solvent-laden atmosphere from buffer container B5 In the debinding phase, heated solvent (hexane) is circulated around the green compacts. Perforated plates at the inlet and outlet sides and the circulation of the solvent work together to create an evenly distributed current B5 Buffer chamber In the drying phase, the solvent atmosphere from the debinding chamber A1 is pumped into the previously...

What can you expect from RENZMANN? In the planning phase After you place your order In addition to the documents you have already received, we will provide you with the piping diagrams, pneumatic plans and circuit diagrams for your future equipment. We work with you to define the steps and responsibilities of the project and to determine what, if anything, needs to be done to prepare your premises for the installation of the equipment. During the quotation stage, we will already create process diagrams and installation plans and define the interfaces to on-site energy supply systems (power,...
