The Danfoss journey to Engineering Tomorrow began on September 1, 1933, when Mads Clausen founded Danfoss in his parents’ farmhouse in Nordborg, Denmark. Since then, the business has grown from a solo enterprise into one of the world’s leading suppliers of innovative and energy-efficient solutions. Passion for innovative customer solutions has been ingrained at Danfoss since Mads Clausen’s very first inventions. From the thermostatic expansion valve for refrigeration systems, to one of the world’s first radiator thermostats for regulating heating, to the world’s first mass-produced frequency converters, all the way to today's telematics used for precision farming.
