FAQ

It's easy to get a quote: Contact us by email at vertrieb@dw-renzmann.de or call us on +49 (0) 6751 878-0. Together, we will analyze your needs - e.g. which parts you want to clean or which solvent you want to treat - and prepare a tailor-made offer for you.

Our sales staff will support you with their in-depth specialist knowledge. In addition, the sales staff work closely with our technical center so that application tests can also be carried out if required.

We have a worldwide sales network. You can find the contact person responsible for your region here. Alternatively, our sales team will be happy to help you directly and put you in touch. For customers in Germany (and selected other countries), sales are handled directly by our company headquarters in Monzingen.

Our consultation begins with an individual inquiry about your requirements and wishes. You tell us your requirements - for example, which parts, containers or solvents you use - and we recommend the right machine for you. For more complex requirements or uncertainties, we offer you washing or distillation tests in our technical center. This allows you to experience under real conditions which system is best suited for you. You can request an appointment for a washing or distillation test directly here.

We need some basic information to provide targeted advice: What is to be purified or distilled? In what quantities? How heavy is the contamination? Are there special geometries or requirements for the cleaning or recovery result? Describe your task to us by e-mail. We will then be happy to send you the appropriate questionnaire. Based on this query, we can create a customized concept for your application.

Our machines are based on proven technology, but can be adapted to customer-specific requirements at additional cost. These include, for example, special adapter systems, control concepts suitable for integration, adaptations to structural conditions or special process-related functions. Simply contact us - together we will check what is technically feasible and economically viable.

Yes, we deliver worldwide and have decades of experience in the production of machines for the international market. Our machines meet country-specific requirements, both in terms of technical standards and regulations as well as documentation. Our local sales partners also support you with communication and project management.

Generally, you will receive your quotation within a few working days. More complex projects that require technical consultation or trials in the technical center may take a little longer. We will keep you informed of the status in a transparent manner. Request a quote.

We supply ATEX-compliant machines for operation with flammable solvents. This is based on Directive 2014/34/EU (current version) and the associated guidelines of the EU Commission. With our distillation units, however, we go one step further than other suppliers. Unlike other manufacturers, we define Zone 0 inside our distillation units. This means that, in addition to all electrical devices, all moving mechanical parts inside the distillation bubble are also type-tested and approved for permanent operation in Ex Zone 0. You can find out more under "Our ATEX protection concept".

Sustainability is not an add-on for us, but part of our technology philosophy: our distillation units allow for the recovery and reuse of solvents, thereby reducing disposal costs and resource consumption. Our washing machines are designed so that cleaning media can be used efficiently and processes can be designed to conserve resources. The durability of our machines also contributes to the environmental footprint.

Some of our machines for washing and distillation tests are available in our technical center in Monzingen. You can experience them live during a test with your own materials. Alternatively, we will be happy to send you technical documentation or reference reports - we can also organize a digital viewing appointment on request. You can find out more about our technical center here.

You can contact us directly via our service hotline or by e-mail. Please have the serial number of the machine and a brief description of the fault to hand.

As a rule, we can respond within 72 hours, depending on the location and availability of our service technicians, prioritizing machine downtimes and associated downtime over all other activities.

Yes, many of our newer machines are equipped with remote diagnostics functions. Our support team can then carry out initial analyses and troubleshooting remotely.

We also offer the option of using AR data goggles (ATEX approved) to guide and support your maintenance staff directly in the field.

Please send your spare parts request by e-mail, stating the machine designation, machine number and part number, if available.

Yes, we offer individual maintenance contracts with different service levels. These include regular inspections, remote support and preferential on-site service. Request your maintenance contract here.

In addition to the inspection intervals specified in the operating instructions (daily, weekly, monthly), which must be carried out by the operator, we recommend annual maintenance by trained Renzmann personnel. You can find more information on this under "Service".

The maintenance intervals depend on the machine type and the intensity of use. As a rule, we recommend an annual inspection by our customer service department. This includes the following services:

• Checking the machines using checklists
• Exchange of standard replacement lines
• Recording of defects (repair as follow-up order)
• Process optimization
• Documentation of all activities carried out

Upon order confirmation you will receive information on the expected delivery time.

Yes, we will be happy to provide you with a digital copy of the operating instructions or technical documentation. Please state the machine serial number and write to us.

We train machine operators and maintenance staff - either at your premises or at our plant in Monzingen. We adapt the content to your individual needs. Simply contact us by e-mail.

As a rule, we guarantee the availability of spare parts for at least 10 years from the production date. We are happy to check the availability of older machines on an individual basis.

Yes, we offer retrofit and modernization solutions, e.g. to increase energy efficiency

The Renzmann technical center is your point of contact for practical washing and distillation trials with your own materials. You send us contaminated components or solvents; we test, analyze and advise - either on site or by means of a detailed analysis report. This enables you to find the right cleaning solution for your specific requirements. Request an offer for your washing or distillation trial here.

We carry out washing trials with ink-carrying parts such as doctor blades, hobbocks or containers - even with complex geometries. We also offer distillation tests with contaminated solvents. So that you can process and reuse them in future with your own distillation unit and thus reduce your disposal costs.

Our tests are based on your real contaminated media, provide practical results and enable a well-founded machine selection. By recovering solvents, we promote sustainable processes. The results help you to invest economically and in an environmentally friendly manner. Request an appointment for a washing and distillation trial here.

Our technical center in Monzingen is equipped with the following machines:

• WM 3400 - Cleaning of parts with hobbock spray lance and hose rinsing
• ROBUS, SKM, SP50 - for round or cubic containers with or without outlet
• ROTOmaX 30 - for the recovery of solvents with batch or refill operation.

All machines cover different requirements and container sizes. Details on the machines can be found here.

You contact us, receive a quote, send in your materials and decide whether you want to take part in person. We will then advise you on your optimum cleaning or distillation solution.
You will always receive a detailed report with before/after pictures. We will also be happy to send you solvent samples by prior arrangement.

If your current cleaning medium - whether solvent-based or aqueous-alkaline - does not deliver the desired results, we will advise you specifically on alternative solutions in the technical center. We can also carry out dissolution tests with various media on site as part of a washing trial. We always have a selection of common solvents available in small quantities so that we can react quickly and flexibly to your cleaning requirements. You can request your personal appointment at the technical center here .

The costs for washing and distillation tests are calculated individually and offset against the price when a machine is subsequently purchased - making the test a worthwhile investment.
