About Danfoss

Few names carry as much weight in the world of refrigeration and climate control as Danfoss. Founded in 1933 by Mads Clausen in Nordborg, Denmark, what began as a modest workshop producing compressor valves has grown into one of the world's foremost suppliers of energy-efficient engineering solutions. Today, Danfoss operates across dozens of countries, serving industries that range from food retail and cold chain logistics to commercial HVAC, industrial automation, and beyond.

Danfoss built its reputation on a straightforward principle: deliver precise, reliable technology that reduces energy consumption without sacrificing performance. That philosophy is embedded in every product line the company offers, making Danfoss components a go-to choice for engineers, technicians, and system integrators who demand dependability under demanding conditions.

Refrigeration & Compression Expertise

At the heart of the Danfoss catalog is an extensive lineup of hermetic and reciprocating compressors — the mechanical workhorses that pressurize refrigerant and keep cooling systems running efficiently. Danfoss compressors are engineered for tight tolerances, quiet operation, and long service life, making them a preferred choice in commercial refrigeration cabinets, walk-in coolers, and light commercial cooling systems worldwide. Their compressor technology traces directly back to the company's founding roots, and decades of refinement show in the performance consistency technicians rely on.

For automotive and mobile climate applications, Danfoss also produces A/C compressors built to withstand the vibration, temperature swings, and variable load demands inherent to vehicle environments. These units are engineered to integrate cleanly with OEM-style systems, providing efficient, consistent cabin cooling.

Parts, Accessories & Electrical Components

A complete cooling system is only as strong as its supporting components. Danfoss offers a broad selection of A/C and refrigeration parts and accessories — including expansion valves, solenoid valves, pressure controls, and fittings — that keep systems balanced and running at peak efficiency. These components reflect the same engineering rigor as Danfoss's larger assemblies: precise actuation, durable materials, and compatibility across a wide range of system configurations.

Electrical reliability is equally critical in any HVAC/R system. Danfoss run and start capacitors are designed to provide the precise electrical boost motors need at startup and the steady support required during continuous operation. Properly rated capacitors reduce motor strain and extend equipment life — a detail that professional technicians appreciate when specifying replacement components.
