D.W. RENZMANN Apparatebau GmbH specializes in cleaning systems for print shops and paint producers, focusing on removing stubborn residues and handling flammable solvents or aggressive alkaline agents. They provide services such as profitability calculations, technical documentation, and worldwide service including installation and maintenance.
RENZMANN designs cleaning processes that comply with environmental and safety regulations. The cleaning involves dissolving residues with washing agents like solvents or alkaline agents, followed by mechanical removal using spray or high-pressure jets. The choice of cleaning technology depends on the items' shape, quantity, and soiling type.
Cleaning machines using flammable liquids must adhere to EN 12921-3 standards, classifying the interior of such machines as zone 0 due to potential explosive mixtures. RENZMANN machines meet ATEX category 2 for external and category 1 for internal explosion protection.
RENZMANN machines comply with directives such as the Machinery Directive 2006/42/EC, ATEX Directive 2014/34/EU, and EMC Directive 2014/30/EU, evidenced by the CE mark and a declaration of conformity.

- SKM: Suitable for large containers, with powerful centrifugal pumps and closed solvent reservoirs.
- Ergonomic outlet cleaning systems, floor plates, and brush hoods for low-emission washing.
- Solvent concentration measuring systems and nitrogen generators for inerting.
- Manual or pneumatic clamping devices and tilting platforms for ease of use.
- Ensure proper installation and maintenance of filters and pumps to prevent operational issues.
- Utilize the automatic washing programs for efficient cleaning cycles.
- Consider additional accessories for enhanced cleaning performance and safety.
The document describes a hydraulic washing chamber door that doubles as a loading platform with a rotating plate, driven by an explosion-proof gear motor. It includes specifications for container alignment, door operation, and internal cleaning mechanisms.
The door features interlocking guide rails for container centering and a polling sensor to ensure the container is locked before operation. The standard model includes conductive polyamide brush rollers for internal cleaning, driven by a hydraulic motor with adjustable speed and pressure.
Options include external cleaning with conductive brushes, a separate outlet cleaning system, warm air drying, a drying chamber to minimize solvent emissions, and a solvent concentration measuring system.
Three models (BKM Size 09/11, 12/13, 15/15) are detailed with specifications for container dimensions, washing pump capacity, air extraction system, and overall dimensions.
RENZMANN offers comprehensive services from planning to post-installation, including process diagrams, installation plans, profitability analysis, and testing in their laboratory. They provide documentation, training, maintenance, and support for regulatory compliance.
