On behalf of Bosch, Berghof develops a method for manufacturing porous films for fuel cells, which Bosch then applies for a patent. The basis is the high-performance plastic polytetrafluoroethylene (PTFE) - commonly known under the name Teflon^®. This lays the economic and technological foundation stone for today's Berghof Fluoroplastic Technology division and for Berghof's successful development into a technology company. Today, porous PTFE as a pressure compensation membrane is successfully used in many technical applications: to protect vehicle headlamps, electronic assemblies, high-voltage accumulators and sensor systems.

Berghof continues its research into innovative membranes - and sets out to conquer new fields, such as medicine. For example, Berghof capillary membranes are an important component of the first artificial kidney that is being clinically tested during these years. Since 1975, Berghof has also been developing tubular membranes for the filtration of process and waste water - the technological foundation for today's Berghof Membranes division, which has since proven its great ability in more than 2,000 projects all over the world.

The know-how in the field of control systems will soon bear more fruit. At the beginning of the 1980s, Berghof also established itself as a developer of software solutions for logistics facilities. In 1982, it was again an order from Bosch that gave the initial spark for establishing another division: Berghof develops a test system for testing alternator regulators for Bosch - and uses the existing and new know-how to adress another field. Customers from the automotive industry in particular to this day still appreciate the intelligent and efficient Test and inspection technology from Berghof Automation, in which our experts combine high-quality industrial standards of measurement technology with our own products - thus ensuring the highest product quality and thus safety and reliability.

With the patent application for the non-contact in-situ temperature measurement method, Berghof Products + Instruments continues to successfully develop its own laboratory instruments. Later, the company develops a patented optical print control process. The big advantage: The instantaneous temperature and pressure measurement directly in the vessels offers significantly increased safety - because this allows spontaneous reactions to be intercepted before potentially serious and expensive accidents occur.

Another world's first, again Berghof Products + Instruments: With the first top-loader microwave, Berghof not only makes working in the laboratory more convenient, but also safer. In addition to the patented optical measurement methods for pressure and temperature already mentioned, Berghof microwaves thus offer additional important advantages.

The high performance and reliability of the "Operations Control System for Transshipment Stations" developed by Berghof - in short: BLU - is also causing more and more of an international sensation. In 2011, the division Process control and logistics from Berghof Automation secures the contract to equip a transshipment station in Poland. In 2016 the BLU from Berghof also conquers Norway: The state's rail traffic administration has the Berghof experts from Mühlhausen in Thuringia equip twelve Norwegian freight handling stations with intelligent and efficient electronic control technology.

Under the motto "50 years of innovation," Berghof celebrates its anniversary with numerous activities - and gives itself a new website as the crowning glory of its completely renewed image since 2013. As early as 2011, Johannes, Georg and Ulrich Maxim Zundel, in the spirit of their father, had worked together with the management team to develop a vision for the successful continued development of the Berghof Group in order to promote visionary ideas through the intensive exchange of creative minds from a wide variety of fields and the intensive partnership with customers - expressed through the common guiding theme: "Your Innovation Hub."

A Sustainable Investment in the Berghof Campus in Eningen. In 2021, the Berghof Group made a bold statement in favor of sustainability by launching a major renovation of its main building. Upgraded façades, modern energy-efficient windows, and a fully overhauled roof – all aligned with the latest energy standards – have significantly reduced the site’s energy consumption. A state-of-the-art combined heat and power plant now supplies the campus with eco-friendly energy. This forward-looking investment not only creates optimal conditions for the future but also highlights Berghof’s strong commitment to sustainable innovation.

The Berghof Group is made up of seven subsidiaries: Automation, Fluoroplastics, Gigahertz Optik, Membranes, Products + Instruments, Environmental Engineering, and, as of January 2025, the newly founded Berghof Process Control & Logistics GmbH. Across eight national and international locations, around 350 highly qualified specialists work in a dynamic environment dedicated to innovation and technological advancement. As a family-owned technology company with a long-term perspective, we focus on sustainable growth and strategic clarity. At the end of 2024, the Mühlhausen site—home to the energy storage testing division of Berghof Automation GmbH—was closed. At the same time, Berghof Process Control & Logistics GmbH was spun off as an independent company to sharpen our focus on profitable business areas. Our values – partnership, versatility, and high standards – form the foundation of strong, trust-based relationships with our customers and partners. Since our beginnings as a research laboratory, the drive to explore new frontiers has been not just part of our identity, but the engine behind our active role in shaping technological change.
