Latin America. Danfoss announced that the newly qualified and tested EVR V2 solenoid valves add to its range of air conditioning components for oil-free and future-proof R1234ze systems.
EVR valves are designed for use in liquid, suction and hot gas lines. They are now compatible with R1234ze oil and refrigerant-free systems which is a viable long-term refrigerant option for a wide range of applications, enabling OEMs and end users to reduce GWP with direct CO2 emissions and reduced refrigerant costs. In addition, oil-free systems help meet energy efficiency requirements and increase industry-leading part-load reliability and excellent efficiency at full load. The oil-free operation also helps ensure long-term performance at nominal levels.
Drew Turner, Global Marketing Manager, Danfoss Cooling Free-Oil solutions stated that "since the launch of the pioneering Turbocor TG compressor in 2013 and our expansion into a full-range portfolio in 2017, we have been market leaders in R1234ze and in the oil-free component qualification test. While other manufacturers test the performance and reliability of their components using air, Danfoss uses refrigerant in real conditions in their Application Development Centers."
He added that testing on complete systems not only provides greater accuracy, but also improves reliability and energy efficiency, "this translates into benefits for our customers and, in fact, also for our customers' customers." The ETS Colibri valve was designed to work with both oil and oil-free. Oil-free compatibility also allows for significant sustainability advantages, with hermetically sealed components reducing the possibility of leakage.
The clear advantages of using R1234ze in oil-free systems mean that Danfoss expects the demand for these qualified components to increase over time. Luigi Zamana, Senior Director of Marketing said "the high standards and rigor with which Danfoss tests its components, means that we can offer leading levels of reliability along with the widest range of capabilities for OEMs."
