Your challenge – our answer
For products related to food and water, hygiene, process safety and compliance with standards are crucial.
We provide both standard solutions and stainless steel tanks and systems tailored to your specific requirements. We take hygiene and compliance with standards into account right from the start of the engineering phase, implement them consistently during production, and thus create the basis for minimal cleaning effort, smooth approvals and reliable operation.
Our services for the food industry
Storage tanks
Our storage tanks are designed for the safe storage of liquids such as water, dairy products, beverages, intermediates, or finished goods. Up to a diameter of 7.5 meters, tanks can be fully manufactured as one-piece units in the factory; larger sizes are realized through flexible on-site assembly.
The focus is on product safety, preservation of quality, and easy cleaning through hygienic design.
Silos
Our silos are designed for the hygienic storage of bulk materials such as flour, sugar, powders, or granulates. Constructed according to Eurocode 3 and available in ATEX-compliant design, they ensure safe handling of dust-explosive materials.
Optional discharge systems and sensor technology support controlled filling and emptying while maintaining product quality.
Tailor-made tanks
Whether aggressive cleaning media, special additives, or demanding process conditions – we supply tailor-made tanks designed for specific requirements.
All solutions are designed for seamless integration into complex process chains while meeting hygiene and environmental standards.
Process tanks
Our process tanks are designed for mixing, reaction, fermentation, and temperature control processes in food production. They are equipped with agitators, heating and cooling systems, and process instrumentation.
Designed according to EHEDG and GMP guidelines, all tanks support CIP cleaning and ensure consistent product quality and maximum yield.
Pressure vessels
Our pressure vessels are designed for the storage and processing of gases and liquids under pressure, such as CO₂ for beverage production or nitrogen for inerting. Certified according to PED and ASME, they ensure full regulatory compliance.
ATEX-compliant configurations are available for applications involving flammable or explosive media.
Tank accessories
In addition to their various applications, our tanks and systems can be equipped with a wide range of accessories tailored to your needs:
Walkway systems for safe access, insulation, agitators, and steel structures in stainless or carbon steel, as well as skid-mounted solutions.
Spare parts and global service ensure safe operation, high availability, and predictable lifecycle costs.
Process plants
Our process plants provide complete solutions including engineering, automation, and installation. They integrate conveying systems, control technology, and CIP systems into a fully coordinated overall concept.
The result is efficient processes, rapid commissioning, and reliable operation.
