Future with tradition

Janitza energy measurement technology. Made in Germany.

Nowadays, energy management is not only relevant for the environment and for society but is also a critical competitive factor. Only those who can keep a close eye on their energy consumption can reduce costs and increase efficiency.

This is a particular focal point for Janitza electronics GmbH, a german company based in the Hessian town of Lahnau which followed on in 1986 as a subsidiary of Eugen Janitza GmbH which was founded in 1961. The product range offered by Janitza provides complete system solutions for modern energy data management (e.g. ISO 50001), power quality and residual current monitoring.

Alongside measurement devices and software, Janitza also offers the associated services – a complete solution that guarantees efficient energy management. This includes: Energy measurement technology, class A network quality analysers compliant with standard EN 50160, energy management systems, digital integrated measurement devices, mobile power quality analysers, power factor controllers, harmonic filters and compensation systems. Alongside consultation and the development of technical solutions, Janitza also carries out commissioning, courses and training with customers and provides maintenance and support for the systems.

Janitza develops and manufactures the complete range of products (hardware and software) at their site in Lahnau, Germany – just as they always have.
