EcoPaintJet painting refrigeration units for supermarkets

Dec 12, 2024

Refrigeration units instead of vehicle bodies: EcoPaintJet now being used in industrial applications. The Boxberg-based company PAN-DUR is using EcoPaintJet to paint the glass surfaces of its deep-freeze islands and multidecks for supermarkets. The overspray-free paint application not only eliminates the need for painstaking masking but also saves material and time.

These units are hard to miss in the supermarket: the large wall multidecks, cabinets, or counters, all with glass panels, showcasing a wide range of foodstuffs within easy reach of shoppers. To prevent the unsightly refrigeration technology at the edges of the glass from coming into view, decorative stripes are applied. PAN-DUR, which makes the glass elements for its refrigeration units from enhanced safety glass, previously used a screen printing process to apply the black, gray, or colored stripes – depending on the appearance of the respective food retailer – to the glass.

Now, EcoPaintJet is replacing screen printing. With this move, PAN-DUR is saving the time-consuming and costly process of changing screen templates before each new paint application. The EcoPaintJet applies the paint to each defined area and in each desired color without any overspray, doing so much more quickly and flexibly than screen printing.

PANDUR paints overspray-free with the EcoPaintJet from Dürr.

Dürr supplying the full range of process technology

Along with the paint applicator, Dürr also supplied all of the process technology to PAN-DUR, from the system for extracting the paint from the containers to the system for dosing it.

The components included the Fluid Board color dosing and color changing system, the cleaner for the applicator, and the AUC control unit, all designed to be “ready2integrate” into existing systems. PAN-DUR linked the individual components with the interfaces in use on its shop floor, developing its own new system adapted for mounting the EcoPaintJet.

The EcoPaintJet paints with sharp edges and without any overspray. As a result, PAN-DUR gains flexibility and speed in production and reduces paint costs.

Other industrial applications are also conceivable for the EcoPaintJet, for example in the wood industry, in window or kitchen construction, but also in the field of painting railway vehicles.

Painting glass is extremely challenging

The biggest challenge during the implementation was finding the right paint composition for use on glass surfaces. Dürr worked on this with specialist paint company Votteler, a long-standing partner of PAN-DUR. Project manager Uwe Schmidt explains: “Painting glass surfaces is very challenging. You need specially developed paints whose rheological properties, coverage, and particle distribution are perfectly tailored to the system. So we needed a few practice rounds until we found the right paint – but we were successful at last.”

Painting trains as a potential field of use

Other industrial fields of use are being planned for the paint applicator, such as in the timber industry and in window or kitchen building. Perhaps the most promising field of use is painting trains. To mask decorative stripes, for example, trains often spend days on the sidings. This could all change with the EcoPaintJet.
