Success Stories made by SAUERESSIG Engineering

SAUERESSIG Engineering – our most important milestones & the success stories that define us.

Discover our developments in engineering with a special focus on machines and components in the field of energy storage – from scalable solutions for the battery industry for which we design and build specialty equipment for the large-scale production of lithium-ion batteries up to efficient systems intended for suppliers of hydrogen fuel cell components, for instance to produce flexible bipolar plates.

As an experienced special machine manufacturer and provider of calender systems we realize individual solutions that are unique worldwide.

The driving force behind our success stories? It’s you. Due to the close cooperation between our engineers on site, our research and development department and your individual requirements, innovative developments can be made – and new milestones be reached.

Together with you, we keep on writing our engineering success stories.

  • With OLBRICH GmbH, further competencies for the growing energy storage market are added to the portfolio – for the production of hydrogen fuel cell components (large-scale production lines for gas diffusion layers, coated catalyst membrane) as well as for battery production (equipment for coating electrodes using wet and dry processes, separator films and battery wrapping lines).
  • Opening of SAUERESSIG Engineering’s new service facility in San Antonio, USA, designed for reconditioning of rollers which are mainly coming to use in specialty equipment for the production of batteries.
  • With Terrella Energy Systems, a supplier of primarily stack ready graphite bipolar plates in small quantities (prototype development), further expertise on the energy and storage market in the field of hydrogen fuel cell systems joins the team, and thus complements existing processes for the production of flexible bipolar plates at SAUERESSIG.
  • Upgrading and expansion of the Competence Center, which functions as a link between lab and large-scale production and offers comprehensive testing facilities, including developments for the battery industry.
