Panel-Tec
Innovative silos in modular construction
Custom-made silos with innovative flange design
Zeppelin Systems, as a global leader in plant engineering, also demonstrates exceptional expertise in the cost-effective construction of silos over 500 m³. The Panel-Tec design, featuring innovative flange design and well-thought-out assembly technologies, impresses with short assembly times while maintaining verifiable Zeppelin quality. The concept: individual silo segments are prefabricated as much as possible at our production facility and fitted with flanges. These segments are transported to the construction site in containers, where they are assembled and bolted together. The silos are then automatically welded from the inside. This ensures that the silos are ready for use in the shortest time, regardless of weather conditions. Additionally, they are expandable – if more storage capacity is needed in the future, the silo can be easily and quickly expanded.
Benefits
Special Highlights
Simple and Efficient Assembly
The silo systems are designed for quick and easy assembly, minimizing time and labor effort.
Optimal Bulk Material Flow
Thanks to the thoughtful design, a continuous and consistent flow of bulk materials is ensured, enhancing the efficiency of the entire system.
Lower Transport Costs
The compact design and modular silo segments ensure optimal utilization of transport vehicles, thereby reducing transportation costs.
Transport & Team
