RITTER energy concepts – for a safe and precise supply.

We can provide power where it is needed for buildings, machinery and lighting. Safely, accurately, and without interruption. For you this means: we will develop a needs-based concept and then ensure a competent implementation.


Corresponding systems are delivered and assembled professionally. If desired, we will then train your team in dealing with the new technology and will continue to be your contact partner for repairs, maintenance and servicing. Our scope of services also includes retrofitting measures for the expansion and modernisation of existing plants.

Designed for reliability – our facilities and systems.

Solutions for highly particular requirements are our speciality. Thanks to many years of experience, we know the requirements of different industries. For example, we provide reliable power supply to hospitals or for drive technology in industry.


With lightning and surge protection, equipotential bonding, earthing systems and structural fire protection, we can maximise the safety of your energy supply. Our services also include emergency backup systems, line filters, grid switching facilities, IT power grids, and much more. Contact us and learn all about our wide range of products and services!
