Safety for Industrial and functional buildings
Lightning and surge protection are important components for ensuring the function of electrical infrastructure in multifunctional buildings as well as systems and production processes in industrial buildings. Because where machines, systems or sensors are in constant communication with each other, a constant power supply and a continuous flow of information are essential.
Prevent unnecessary risks. Protect functional buildings and industrial production processes. We support you in this – with a holistic concept for lightning protection and surge protection, with our sophisticated and efficient products and with our more than 100 years of experience.

Lightning protection keeps your business running
For companies, the trouble-free operation of their production facilities, office or commercial buildings is of key economic importance. Processes, systems and communication technology must also function reliably in the event of lightning and surges.
Ensure the professional protection of energy and IT systems! With a holistic lightning and surge protection concept that covers the building envelope as well as the power supply and data technology. We are your reliable partner for all questions relating to internal and external lightning protection. Please get in touch with us! On request, we can support your project right from the planning phase and provide you with the optimum product composition for your requirements.

What other topics are of interest to you?

Maintaining infrastructure
Surge protection for applications in buildings ensures that your basic supply structures function stably and safely.

Securing power generation
Surge damage due to thunderstorms is one of the most frequent causes of damage to photovoltaic systems. Protection measures increase the availability of your system and secure the yield in the long term.

E-Mobility
From the wall box to AC/DC charging stations right through to high-power charging parks and bus charging stations: we offer comprehensive protection concepts and solutions to plan, build, check and operate these safely, efficiently and in a standard-compliant manner.
