The Danfoss EVR v2 is a complete range of servo-operated solenoid valves for air conditioning and refrigeration systems. With connection sizes ranging from 1⁄4 in. to 2 1⁄8 in., EVR v2 valves were already one of the most versatile solenoid valves available; now that they can be used in oil-free and R-1234ze systems, EVR v2 valves are more adaptable than ever before.

R-1234ze is a viable, long-term refrigerant option for a wide range of applications, and enables OEMs and end users to reduce GWP, resulting in direct CO2 emissions and refrigerant cost reductions. What’s more, oil-free systems help meet energy efficiency requirements and increase reliability, with industry-leading part-load and excellent full-load efficiencies. The oil-free operation additionally guarantees long-term performance at rated levels.

Drew Turner, global marketing manager for oil-free solutions, Danfoss Cooling, stated: “Since we launched our pioneering Danfoss Turbocor® TG compressor in 2013 and expanded to a full range portfolio in 2017, we’ve been market leaders in R-1234ze and oil-free component qualification testing. While other manufacturers test their components’ performance and reliability using air, Danfoss uses refrigerant in real-world conditions in its Application Development Centers.”

The clear advantages of using R-1234ze in oil-free systems explain why Danfoss expects demand for these qualified components will only increase over time.

Luigi Zamana, senior director of marketing, said: “The high standards and rigor to which Danfoss tests components, combined with the sheer size of our component portfolio, means that we can offer leading levels of reliability along with the widest range of capabilities for OEMs.”
