The world of industrial refrigeration is developing rapidly with the usage of various refrigerant changes and new ways of designing systems emerging. To embrace the new developments, Danfoss is pleased to introduce a new range of SVL valves approved up to 65 bar and has a temperature range from - 60°c to 150°c. The characteristics of the new valve make it perfectly suited for the requirements of industrial ammonia (R717) heat recovery systems as well as subcritical CO2
Using a higher pressure has several advantages. For subcritical CO2
systems, the higher pressure means that smaller stand-still units can be used or left out entirely as the saturation temperature rises from 16°C to 25,5°C. Furthermore, the higher pressure enables hot gas to be taken from the transcritical side.
