About Danfoss

Our Story

Engineering Since 1933

Danfoss was founded in 1933 in a small workshop in Nordborg, Denmark by Mads Clausen. From a single automatic expansion valve for refrigeration systems, the company has grown into a global technology group employing over 42,000 people across more than 100 countries.

Today, Danfoss develops and manufactures products and solutions spanning HVAC and refrigeration, drives, power conversion, and mobile hydraulics. Our technologies are found in hospitals, office towers, supermarkets, data centers, ships, and construction equipment on every continent.

The company remains headquartered in Nordborg, Denmark and continues to be majority-owned by the Bitten and Mads Clausen Foundation — a structure that prioritizes long-term investment in engineering research over short-term financial returns.

How We Work

Guiding Principles

Engineering excellence is not just a tagline at Danfoss — it is reflected in how we design products, certify quality, and serve customers across complex industrial environments.

No Compromise on Technical Integrity

Every Danfoss component is validated against published technical specifications before release. Where performance varies by installation or ambient conditions, our datasheets disclose the test methodology and applicable caveats. We do not publish marketing claims without supporting technical evidence.

Climate Mandate

Danfoss has committed to achieving carbon neutrality in its own operations by 2030 and supports customer decarbonization pathways through product energy efficiency improvements. Our low-GWP refrigerant adoption roadmap aligns with EU F-Gas regulation phase-down schedules.

Transparent Limitations

We explicitly communicate where our products are not the optimal solution. Danfoss drives, for example, deliver maximum savings in variable-torque applications such as centrifugal fans and pumps. In constant-torque applications, actual energy savings are considerably lower — a fact we communicate clearly to avoid mis-specified systems.

Long-Term Partnership Model

With no short-term shareholder pressure from public stock markets, Danfoss invests a higher-than-industry-average proportion of revenue into R&D. This allows us to develop platform technologies — like magnetic bearing compressors and digital displacement pumps — that require decade-scale investment horizons.
