Engineering Excellence in Variable Frequency Drives

Founded in 2004 by a team of power electronics engineers, Danfoss VFD was built on a single conviction: that variable frequency drives should deliver measurable performance advantages under real operating conditions — not just on datasheets.

Over two decades, we have invested consistently in motor control algorithm R&D, functional safety engineering, and multi-protocol communication architecture. Today, our 120+ active patents span sensorless vector control, active harmonic mitigation, and IEC 61800-5-2 integrated safety — technologies that translate directly into energy savings, reduced downtime, and simplified system integration for our customers.

With three manufacturing sites, ISO 9001 and ISO 14001 certified quality systems, and a technical support network spanning 45 countries, we serve EPC contractors, system integrators, OEM machine builders, and industrial end users across HVAC, water treatment, oil and gas, mining, and general manufacturing sectors.
