Wallstein Holding GmbH & Co. KG

From sheet metal fabrication to highly complex pharmaceutical solutions: our sterilization tunnels are synonymous with precision and quality.


For over two decades, we have been a trusted partner to the pharmaceutical industry and have installed more than 1,000 sterilization tunnels worldwide. Every system is a bespoke solution – precisely manufactured to our customer specifications.

Our systems play a central role in the sterilzsation and depyrogenation of glass containers such as ampoules, cartridges and vials. A dry, hot air stream in a laminar flow reliably inactivates microorganisms and pyrogens thermally – using precisely defined temperature profiles.

The process in an overview:

  • Gentle handling and preheating at the inlet
  • Sterilization and depyrogenisation at over 300 °C in the heating section
  • Controlled cooling in the cooling section until transfer to the filling line

High-quality materials such as stainless steel, precise temperature measurement via thermocouples and uniform air flow ensure maximum process reliability. Intelligent conveyor systems with jam detection ensure gentle transport of the sensitive glass containers.

Thanks to their modular design, the sterilization tunnels can be flexibly integrated into existing lines – from small pharmaceutical plants to large production facilities.

Awards for quality, on-time delivery and cost-effectiveness, as well as our classification as an A-grade supplier by a leading manufacturer of filling and packaging technology, underscore our expertise and reliability.

Pharmaceutical technology of the highest standard – precise, safe and in use worldwide.
