Danfoss R-1234ze and Oil-Free Components
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.
