We specialize in the design, construction, and technological advancement of plants for producing engineering plastics. Each installation is precisely tailored to your products and requirements. Our core expertise lies in integrating all components for conveying, mixing, dosing, storage, and dust removal into a cohesive system that centers on your high-quality bulk materials. Introducing product into reactors is also well within our capabilities, as we understand the unique demands of engineering plastics. With our extensive, long-standing experience in this sector, you can rely on Zeppelin Systems as your trusted partner. Together, we’ll maximize the performance of your processes—regardless of location and even under the most extreme conditions. Our commitment doesn’t end with plant delivery: we remain available after commissioning for trial runs, training, and service. With our 360° service, you’ll receive professional support at every phase of your project.

CAPEX in focus



Despite the complex demands of engineering plastics, there is significant potential for savings here as well. The key lies in efficient products and a cost-conscious approach. These foundations are established collaboratively at the very early stage of the project. Thanks to Zeppelin Systems’ outstanding global presence, local resources are leveraged to the fullest—across engineering, procurement, and on-site services.

Low OPEX



Our sophisticated solutions for a variety of products deliver larger batch capacities with the highest quality and low energy consumption. For example, hydraulic conveying ensures low operating costs—saving between 60 % and 80 % of energy costs compared to pneumatic systems. Other methods, such as strand conveying or IntraFlow, enable a significant reduction in gas volumes and, consequently, smaller pipe diameters.

High product quality is achievable



In the manufacture of plastics and in downstream logistics, the product is subjected to mechanical stress. We focus on the quality of the end product and the purity of the bulk material, selecting the optimal process for your product. Our proven sifters effectively remove dust particles, fibers, and ‘angel hair.’ Because engineering plastics can also generate substantial fiber formation, we have developed the VGS and FVS series to reliably separate oversized fibers. For cleaning plastic granules—such as removing fiber nests and strands—we use drum screens. Cyclone separators are employed to separate bulk solids from gas streams, for example in pneumatic conveying systems.

Deep Process Expertise with Attention to Detail



We are highly valued for the seamless integration of our systems and components into the overall process. We develop your entire material supply chain—from raw material to final product—whether it is bagged or shipped in bulk.

Process-Oriented Conveying Technology for Superior Product Quality



Conveying distances of up to 1,000 meters—or even beyond—are not uncommon for both commodity and engineering plastics. Our patented Cyclo Feeder, combined with hydraulic conveying, ensures extremely gentle product handling over such distances, with minimal abrasion or loss.

Tailored Degassing and Mixing Technology



In the world of engineering plastics, process or raw-material fluctuations need not result in variable product quality. We offer process silos for degassing, heating, and cooling, as well as mixers. Our mixing silos compensate for irregularities in good time: from Multi-Pipe and Multi-Channel units for large volumes, to the Multi-Flow version for small batches and technical plastics, and even fluid-bed mixers for bulk solids with particle sizes below 500 μm. Each installation is customized to your product requirements.
