Danfoss Radiator Thermostat

Danfoss is an internationally recognized engineering company founded in 1933 by Mads Clausen in Nordborg, Denmark, initially established as Dansk Køleautomatik- & Apparatfabrik. The company revolutionized home climate control in the mid-20th century by inventing and patenting the thermostatic radiator valve, which remains a staple in heating systems across Europe and worldwide.

Danfoss operates extensive manufacturing facilities globally, including major production sites across Denmark, Poland, and other European countries for its climate solutions and heating division. Today, the Danfoss Group remains privately owned, primarily by the Bitten & Mads Clausen Foundation along with the Clausen family, ensuring long-term Danish ownership and stewardship of the engineering giant.
