Washing machine SPF

On our homepage, you can start by specifying the type of material you need to clean. Do you want to clean parts, containers, or rollers and cylinders? You will then see an initial selection of our available machines.

In addition to the type of items being washed, the quantity, degree of soiling, and your production process are also key factors. For container washers, important considerations include the container’s shape (cubic or round) and whether it has a spout.

We offer washing machines equipped with brushes or spray bars. Additionally, it is important to consider whether you are cleaning with solvents or alkaline solutions. We would be happy to provide personalized advice tailored to your specific needs. You also have the option to schedule a test run at our technical center and clean your actual soiled parts in our machines. This will allow you to see for yourself how efficient and safe our machines are.

A container washing machine automatically cleans industrial containers such as mixing tanks, IBCs, batching tanks, and many others using rotating spray systems or modern brush technology, as well as suitable cleaning agents. Depending on the application, it can remove paints, varnishes, resins, or printing inks. Automated container cleaning ensures consistent cleaning results and significantly reduces manual labor. Downtime is minimized and manufacturing processes are optimized. Explosion-proof cleaning systems, such as those from Renzmann, also offer a very high level of safety when cleaning with solvents.

Modern container washers are suitable for cleaning a wide variety of industrial containers. These include mixing tanks, mixing vessels, batching tanks, transport containers, printing ink tanks, stainless steel containers, and IBC containers (made of steel). A special cleaning solution is also available for bunghole drums.

Depending on the container size, degree of soiling, and cleaning requirements, different cleaning methods and machine designs are used.

RENZMANN’s container cleaning systems can be designed for a variety of container geometries and applications. Even containers with attachments, outlets, or complex internal contours can be cleaned efficiently and consistently. This allows for the reliable removal of coatings, paints, printing inks, adhesives, and other production residues.

Choosing the right container washer depends, among other things, on the container dimensions, the media used, and the requirements for industrial container cleaning. For more information, see“Which machines clean containers?”

Depending on the machine, containers of very different sizes and shapes can be cleaned. Our washing machines for smaller transport containers can clean containers with a diameter as small as 350 mm. The minimum height of the container to be cleaned is 200 mm. However, common diameters for mixing tanks and containers range from 600 mm to 1,700 mm. Container heights range from 700 mm up to 1,700 mm. Our Robus can clean containers with a diameter of up to 2,050 mm; the maximum container height is 1,700 mm.

Do you have specific requirements? Please feel free to contact us. We regularly customize our machines to meet individual customer needs and can advise you on which solutions make the most sense from both a technical and economic standpoint.

The duration of a cleaning cycle depends on various factors. The most critical factors include the type and degree of contamination, the container’s geometry, the cleaning agents used, and the requirements for the cleaning result.

In addition to the actual washing time, the on-site exhaust air capacity and the logistics of the items being cleaned also affect the total cycle time. For example, the time required for exhaust ventilation after the washing process, as well as the time needed to load and unload the containers or parts, all impact the overall cleaning process.

Depending on the degree of contamination, system configuration, and operating conditions, container and parts cleaning machines can typically perform between two and four cleaning cycles per hour. Automating container cleaning ensures consistent cleaning results and a high level of process reliability.

Renzmann helps customers design the right cleaning solution to ensure that cleaning performance, throughput, and cost-effectiveness are optimally tailored to their specific production requirements.

We offer a variety of washing machines for container cleaning. The right choice depends on the size of the containers to be cleaned, their exact shape (round or cubic, with or without an outlet), the available space, and the cleaning agent used (solvents or aqueous cleaners).

Washing machines for solvent cleaning:

Our ROBUS, RIO-VSmarT, SP, and BKM models are suitable for round containers with spouts. While the ROBUS combines a spray system with brush cleaning, the RIO-VSmarT relies solely on brush cleaning. The SP features high-pressure cleaning via a spray head and nozzles. The BKM combines brush rollers and a spray system, cleaning not only the interior but also the exterior (optional).

Our SKM is particularly well-suited for cleaning both the interior and exterior of round containers, with or without a spout, especially those with a large diameter. It cleans the interior using a rotating spray lance.

Our 6090 is ideal for round containers without a spout and with a small diameter. It cleans both the inside and outside with brushes.

Our SP is suitable for cubic containers such as steel IBCs.

Washing machines for cleaning with aqueous alkaline solutions:

Here, too, our SP70 is the right choice. It uses a spray pressure of 70 bar to tackle stubborn dirt and is therefore suitable for use with aqueous alkaline solutions.

Using an automated container washing machine can help companies significantly reduce the costs of container cleaning. Compared to manual cleaning, this approach allows for the standardization of cleaning processes, shorter cleaning times, and more efficient use of personnel resources.

In addition, it is possible to optimize the use of cleaning agents, avoid waste caused by inadequately cleaned containers, and reduce production downtime. Automated container cleaning ensures consistent cleaning results, greater process reliability, and consistent cleaning quality.

Additional cost-saving opportunities arise from combining a container washing machine with a distillation system. This allows used solvents to be recycled and reintroduced into the cleaning process. This closed-loop system reduces the consumption of new solvents, lowers disposal costs, and helps companies implement sustainable circular economy concepts.

In addition to the economic benefits, automated container cleaning also helps improve workplace safety. Employees come into contact with cleaning agents, solvent fumes, or contaminated containers much less frequently, which improves working conditions and reduces potential health risks.

The actual savings potential depends on factors such as the number of containers to be cleaned, the degree of soiling, the cleaning agents used, and operational processes. Renzmann helps customers find a cost-effective and sustainable cleaning solution that is optimally tailored to their specific requirements.

Container washing machines are designed to reliably remove a wide variety of production residues. Depending on the application and the cleaning agent used, these machines can remove, among other things, lacquers, paints, printing inks, resins, adhesives, coating materials, and solvent-based or water-based residues from containers.

The use of tailored cleaning processes allows even stubborn dirt and dried-on product residues to be effectively removed. Modern container cleaning systems ensure consistently high cleaning quality and reproducible results.

The types of contaminants that can be removed depend on factors such as the cleaning medium used, the degree of contamination, and the tank geometry. For demanding applications, Renzmann offers customized solutions for industrial tank cleaning. At Renzmann’s in-house technical center, you can also have your actual contaminated tanks cleaned to find the perfect solution for your needs.

Depending on the application and the type of contamination, container washers can use a variety of cleaning agents. These include, in particular, solvents as well as aqueous cleaning agents based on alkaline or specialized detergents.

The choice of an appropriate cleaning agent depends on various factors, such as the residues to be removed, the production materials used, and the cleaning quality requirements. While solvents are often suitable for removing paints, printing inks, resins, or adhesives, aqueous cleaning methods are primarily used for water-based products and certain industrial applications.

Renzmann offers solutions for both solvent-based and aqueous tank cleaning and helps companies select the optimal cleaning method for their specific process.
