Special-purpose equipment
Where standards end, our work begins. We build complex custom equipment, prototypes, and one-of-a-kind designs that are precisely tailored to your unique process engineering needs. Custom geometries and specialized material combinations are our specialty.
Maximum pressure resistance, consistently safe operation
We manufacture pressure vessels for a wide range of applications in the process industry, custom-built according to customer drawings and specific application requirements. They reliably withstand overpressure, vacuum, and aggressive media, and are designed for high operating pressures, fluctuating loads, and thermal cycles. Tight manufacturing tolerances, end-to-end material traceability, and comprehensive test documentation ensure that every vessel remains dimensionally stable and meets testing standards even under extreme conditions.
Manufacturing Details
There is no one-size-fits-all solution for custom equipment: geometry, material, and the scope of testing determine operational safety and durability. We manufacture each one-of-a-kind unit precisely according to your specifications and ensure quality at every stage of production through comprehensive material traceability and testing in accordance with industry standards.
Manufacturing up to these dimensions
Manufacturing up to the following dimensions:
Diameter up to 5 m, single-piece length up to 50 m, individual weight up to 150 t, wall thickness up to 100 mm
- Can be produced in multiple parts
- Also available in horizontal or vertical configurations
- Segment-based manufacturing optimized for transport of large tanks
- On-site assembly or assembly-friendly delivery available
In specific cases, we are happy to evaluate the feasibility of larger dimensions, special materials, and customized additional services. Please contact us—we will work with you to develop a suitable solution for your application.

Questions about custom equipment manufacturing
How does the development of a one-of-a-kind product work? What unusual materials can be processed? In these FAQs, we provide insight into how we work with you to implement customized special solutions—from the initial sketch to final acceptance.
How long does it take to develop a new piece of equipment or a new vessel? + − Development time varies depending on the complexity of the project. For simple vessels, the design can be completed in a few weeks, while more complex projects, such as custom-designed reactor vessels, can take several months. However, we always provide transparent project planning and keep all stakeholders informed of progress.
