About us
Swiss engineers who have spent three decades on one problem.
Systron EMV GmbH exists to make low-frequency magnetic fields predictable, controllable and compliant — for utilities, industry, healthcare, research and infrastructure worldwide.
30+ years experience
Founded in 1993, we have built one of the deepest project archives in low-frequency magnetic field engineering — and every new simulation is calibrated against it.
Swiss engineering
Precision, documentation discipline and independence. Working daily under ORNI, the world's strictest precautionary regime, sets our standard everywhere else.
Worldwide projects
Delivered in 35 countries across Europe, the Middle East, Asia and the Americas, with our own supervisors on site.
Turnkey solutions
Measurement, simulation, engineering, prefabrication, installation and verification under one contract and one responsibility.
