Company historyEdit

  • Danfoss founder Mads Clausen was born in 1905 on a farm in the southern part of Denmark, near the German border. In 1933, after graduating in engineering, he returned to his birthplace and started up a company in the attic of his parents’ farm house.
  • In the 1930s, helped by high customs barriers and import bans on certain products, Clausen was successful in producing and selling a long list of automatic valves for refrigeration plants, which had previously been imported from the United States.
  • In the 1940s an expansion of the factory was completed, and Danfoss agents were set up in Belgium, Norway, Finland, Spain, Sweden, the Netherlands and England.
  • In the 1950s piecework was introduced at the factory and the number of employees rose above 2,000.
  • In 1966 Mads Clausen died of a heart attack at the age of 60. His widow, Bitten Clausen, continued to lead the company as chairman of the board with Andreas Jepsen as president and CEO.
  • In 1983 Danfoss celebrated its 50th anniversary and the 1,000th employee to reach 25 years of service.
  • In 1996 Jørgen M. Clausen, son of Mads Clausen, was appointed president and CEO of the Danfoss Group.
  • In 1997 sales exceeded €2,200 million and the number of employees reached 18,200.
  • In 2000 Danfoss’s business segment Mobile Hydraulics merged with the German company Sauer, Inc. to form Sauer-Danfoss. Jørgen M. Clausen became chairman of this company. Danfoss currently owns 55.4% of the stock, which is traded on New York Stock Exchange.
  • In 2007 the Danfoss group expanded its facilities in Denmark, Canada, China, United States, Romania, Poland and France  with about 130,000 sq m of production, warehouse and office facilities.
  • In 2008 Danfoss celebrated its 75th anniversary and the 40th anniversary of the VLT frequency converter. Jørgen M. Clausen retired as CEO at his 60th birthday. Niels B. Christiansen became the new CEO.
  • In 2010 Munich-based industrial holding company Aurelius AG acquired Danfoss Compressors GmbH from the Danfoss Group, Denmark. The agreement to take over the Danfoss Compressors business was signed in July 2010. In connection with the new ownership Danfoss Compressors has changed its name to Secop GmbH.[citation needed]
