As part of Danfoss’ wide range of servo-operated solenoid valves, its newly-qualified EVR valves have been designed to be used in liquid, suction, and hot gas lines, and are now compatible with R1234ze refrigerant and oil-free systems.

“Since we launched our pioneering Turbocor TG compressor in 2013 and expanded to a full range portfolio in 2017, we’ve been market-leaders in R1234ze and oil-free component
qualification testing,” claimed Drew Turner, Global Marketing Manager for Danfoss cooling oil-free solutions.

“While other manufacturers test their components’ performance and reliability using air, Danfoss uses refrigerant in real-world conditions in its application development centres. We
believe testing in complete systems not only delivers greater accuracy, but also improves reliability and energy efficiency—a win-win situation for our customers, and indeed, their customers too.”
