International. Danfoss has recently announced the launch of its new EVR v2 solenoid valves, which come to complete the improvements introduced in its range of EVR valves throughout the past year.
Their empowerment and rationalization now allow the valves to accept higher refrigerant pressure and a wider range of applications, while reducing the number of references, the stock and the repair time.
Among the most notable advantages for professionals are their lower costs of application and operation without compromising reliability in all applications, from cold rooms to chillers and heat pumps, to give some examples. Thanks to the experience and the Danfoss solutions, it is possible to reduce the energy consumption up to 50%.
Increased opening differential pressure and new functions compatible with modern refrigerants
The range of EVR solenoid valves is present in a wide variety of air conditioning and refrigeration applications, such as large refrigeration chambers, display freezers and refrigerators, as well as chillers, rooftop equipment or for high density spaces (close control). Ten key functions have been applied to improve the robustness of the design in more applications, increase functionality and facilitate repairs.
In air conditioning, the same EVR solenoid valve model, designed to withstand a maximum maximum operating pressure of up to 45 bar, is compatible with higher pressure refrigerants such as R-410A and is valid for heat pumps or chillers that work at room temperature (up to 130 ° C for bypass and defrosting by hot gas) for maximum load. Its approval is provided in 2018 so that they can be used in other flammable and flammable refrigerants in larger chillers.
In refrigeration, this platform is approved for refrigerants with a lower global warming potential, such as R-290 (propane). The sealed closures of the solenoid protect the system and food, in addition to improving the flow to increase efficiency. In the liquid line, the tightness prevents the refrigerant from flowing back into the compression section.
