Danfoss Parts & Automation Components

Danfoss was founded on September 1, 1933, when engineer Mads Clausen began manufacturing a thermostatic expansion valve of his own design in his parents' farmhouse in Nordborg, Denmark — a valve he'd first built the previous November, driven partly by a wartime ban on importing American valves. Originally named Dansk Køleautomatik- og Apparatfabrik, the company was renamed Danfoss in 1946 (combining "Dan" for Denmark and "foss," the Scandinavian word for a flowing river). Still headquartered next to the Clausen family farm — now home to the Danfoss Museum — the company remains majority family-owned through the Bitten og Mads Clausens Fond, employing nearly 42,000 people worldwide and serving customers in over 100 countries across refrigeration, HVAC, motor control and fluid power.
