„Have you already tapped into your potential? This workshop will provide you with the answer.“

Sebastian Hook, Strategic Sales Manager,

What drives you? And what drives you crazy?


Our design engineers are closely networked with in-house production and international research. Here we develop innovative, technically feasible and affordable products for future markets.

Software development

Software development

system solutions

Our embedded real-time systems utilise model-based software development with Matlab/Simulink and Targetlink. Rapid control prototyping ensures fast development of control systems.

The software quality is ensured through the implementation of modern code analysis tools; customer-specific diagnostic functions make servicing easier.

Testing equipment development

Testing equipment development

Product-specific and fully
integrated into production

An experienced in-house team of testing and analysis specialists is responsible for the highest possible quality – product-specific and totally according to your requirements. The testing equipment is linked in to the production processes and automated production centers.

In-circuit-tests, function tests and product-specific tests ensure 100% testing coverage.


Hardware development

Complete systems at the
highest level

PRUFREX develops high-performance control units and ignition spark generators. Our hardware guarantees minimum dimensions due to maximum integration densities. Featuring an EMC robust design, it provides support for all popular interfaces and protocols.

Our Hardware development team work closely with our in-house production to ensure efficient prototyping and production-oriented engineering from the outset.



From concept to production

With our own product and tool design we support development from the first concept through design safety and prototyping all the way to the first production run.

RAPID prototyping with own 3D printer, CAD/CAE development and a broad spectrum of further analysis, simulation and design tools ensure the fulfilment of technical and budgetary requirements.

Test und Analyse

Testing and analysis

Modern test stations, developed by Prufrex

Environmental tests, materials analyses, shock resistance measurements, thermal gradient tests, endurance runs - our testing and analysis department rates, tests and qualifies components and products under realistic conditions.

We safeguard all development phases with wide-ranging tests and account for reliability of 100% in the final application.
