We play an active role in the main growth themes in a world that is rapidly changing: infrastructure, food, energy and climate are the focus of our business. Cities for millions that touch the sky. A richer harvest to feed a growing world. Keeping food fresh and our children warm in a world that can make more out of less.
Our Aspiration: We are Engineering Tomorrow. We passionately push boundaries on results and reputation.
Our Promise: We earn customer loyalty through excellence in Quality, Reliability and Innovation.Our Behaviour: We build our business on trust and integrity. We are innovative in our ambition to exceed expectations. We are global and embrace diversity. We treasure sustainable results.
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.
We strive to deliver solid and sustainable financial results. Find the latest information about our financial performance here, or browse through the archive of reports, presentations and press releases.

The following types of hydrocarbons are commonly used as refrigerants:
A number of other hydrocarbons, such as blends containing ethane, propane or butane, are also used as refrigerants.
Propane has been discussed since the late 1980s as a replacement for CFCs and HCFCs. It has a long history in refrigeration and is thus an interesting candidate. However, its flammability has limited its use. While isobutane (R600a) was introduced in household appliances in some parts of the world from the start of CFC phase out, R290 was introduced later and replaced R134a, R22 or R404A in some appliances.
Hydrocarbons are highly flammable and must be handled with care. If they are used responsibly, hydrocarbons can be employed in a variety of refrigeration and air conditioning applications. In order to ensure safety, hydrocarbon applications are governed by various international, regional and national standards and regulation. Hydrocarbons can only pose an explosion risk if the concentration is between the lower and upper flammability limits. When following the safety standards the concentration of leaked refrigerant will not get above LFL where ignition sources can ignite it, even in extreme situations. The necessary safety precautions and system design depend on the refrigerant charge. In general ignition sources inside the application must be avoided. Most hydrocarbons are non-toxic, with the main safety risk coming from their flammability, although gaseous hydrocarbons are heavier than air and will displace air in lungs.
