Danfoss engineers technologies that enable the world of tomorrow to do more with less. We employ more than 25,000 people and serve customers in more than 100 countries.
Foundation and family ownership ensures a high degree of stability and continuity, as well as providing a long-term and strategic perspective in the development of Danfoss.
Our Engineering Tomorrow mindset dates back to 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 energy-efficient and innovative solutions.
The expansion valve was the very first Danfoss product, which Danfoss founder Mads Clausen developed in the early 1930s. The product was launched onto the market in 1933 and, today, the fifth generation of the valve is sold around the globe – helping to keep food fresh and buildings cool in various refrigeration and air-conditioning systems. We are now one of the world’s leading producers of expansion valves.
In the 1940s, we were one of the first companies in the world to design a radiator thermostat, helping house owners control the temperature in their living room – and avoid energy waste. The first mass-produced thermostats were launched onto the market in 1952.
Thanks to hermetic compressors in a new compact design, Danfoss founder Mads Clausen anticipated that all families would have their own refrigerator. The first compressors were sold under a license in 1952, but demand was strong, so we began to develop and sell our own compressors from 1956.
In 1968, we were the first company in the world to mass-produce frequency converters. The product helped control the speed of electrical motors by regulating the frequency. Today, we produce around a million VLT® frequency converters annually, which typically saves between 15 and 40% energy.
At the beginning of the 1960s, we entered the hydraulics business producing the so-called orbital motor under a license for use in agricultural and construction machines. Our hydraulic products have since helped support the living conditions of the world’s constantly growing population and, today, hydraulics makes up approx. a third of Danfoss’ activities.
For the past 80 years, we have engineered to create positive change, often improving performance, often reducing energy consumption. Today, we invest around 4 percent in innovation measured as a percentage of sales, ensuring the stream of new solutions continues. And on average, every day we are granted a new patent.
