A future with tradition
Today, energy management is not only relevant for the environment and society, but also a decisive competitive factor. Only those who keep an eye on energy consumption can reduce costs and increase efficiency.
Janitza offers complete system solutions for modern energy data management (e.g. in accordance with ISO 50001) as well as solutions for power quality and residual current monitoring. Janitza electronics GmbH, a German company based in Lahnau, Hesse, emerged in 1986 as a subsidiary of Eugen Janitza GmbH, which was founded in 1961.
In addition to measurement devices and software, Janitza also offers related services – a complete solution that guarantees efficient energy management. These include: Energy measurement technology, class A power quality analyzers in accordance with the EN 50160 standard, energy management systems, digital panel meters, mobile power quality analyzers, and load management controllers. In addition to providing advice and developing technical solutions, Janitza also carries out initial commissioning, training, and coaching with customers, and maintains and supports the systems.
Janitza develops and manufactures products at its Lahnau site in Germany.
