Danfoss adds to its extensive range of air conditioning system components qualified for future-ready R1234ze and oil-free systems with the newly qualified Danfoss EVR V2 solenoid valves.
Danfoss EVR V2 solenoid valves
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.
R1234ze 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 efficiency.
Oil-free operation
The oil-free operation additionally helps guarantee long-term performance at rated levels. Drew Turner, Global Marketing Manager for Danfoss’ cooling oil-free solutions stated, “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.
Drew Turner adds, “While other manufacturers test their components’ performance and reliability using air, Danfoss uses refrigerant in real-world conditions in its Application Development Centers. 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.”
High industry standards tested for reliability
Danfoss’ qualified components are not only tested to the highest industry standards for leading levels of reliability, but they’re also designed with the future in mind—with products like the ETS Colibri valve designed to work with both oiled and newer oil-free systems. The clear advantages of using R1234ze in oil-free systems means that Danfoss expects demand for these qualified components will only increase over time.
Luigi Zamana, Senior Director of Marketing at Danfoss said, “The high standards and rigour to which Danfoss tests its 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.”
