Dial-in performance for refrigeration and HVAC/R systems

In refrigeration and advanced HVAC/R applications, the difference between “running” and “running right” comes down to control. Danfoss® is a global leader in compressor controls, electronic valves, and sensing solutions that help systems maintain stable operation under changing load and ambient conditions.

Whether you’re replacing a failed part, optimizing superheat, improving defrost control, or troubleshooting nuisance trips, Danfoss components are built for accurate feedback and dependable actuation—supporting better temperature control, better protection, and better efficiency.

For the fastest match-up, verify part numbers, electrical requirements, refrigerant type, connection size, and control protocol where applicable.

Danfoss Controls & Components — FAQs

How do I match a Danfoss valve or sensor?

Match by part number, refrigerant type, connection size/type, pressure range (for transducers), and electrical/communication requirements (for controllers/EEVs).

Do electronic expansion valves require a controller?

In most applications, yes—EEVs are driven by a compatible controller using sensor feedback to regulate superheat and maintain stable performance.

What info do you need for a fast quote?

Provide the Danfoss part number, system application, refrigerant, voltage, and any connection or range details shown on the label/spec sheet.
