01 · Prefabrication

Precisely prefabricated, assembled faster

Following preliminary planning and work preparation, we prefabricate the required components at our modern production facilities. Detailed design and prefabrication are the basis for smooth assembly.

Thanks to standardisation and precise prefabrication, we significantly shorten the build and assembly time of our vehicles and thus reduce costs considerably. Prefabrication under optimum conditions is the foundation for an end product of the highest quality. Motivated employees and processes certified to DIN EN ISO 9001 ensure this quality, combined with excellent adherence to schedules and short delivery times.

02 · Tank construction

Vacuum/pressure tanks from our own production

The right technology and experienced employees are the prerequisites for efficient production and consistently high quality — down to the last detail.

  • all vacuum/pressure tanks and non-pressurised tanks
  • in all weldable steels and in stainless steel
  • with factory or TÜV acceptance and all required documentation
  • exclusively for our own use
  • fully and semi-automatic rolling, trimming and welding systems
  • automated circumferential and longitudinal seam welding systems for perfect welds

Experienced welders additionally ensure a high degree of flexibility in the manufacture of our vacuum/pressure tanks.
