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 (R744) systems.
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.
For ammonia heat pumps the higher pressure allows for a rise in the saturation temperature from 90°C to 102°C. This means you can have same capacity with fewer compressors and a higher supply temperature which enables the water to be used in a broader application range.
The new valve is available in sizes and connection variants:
The valve is based on the acknowledged SVL platform which above all is characterized by flexibility. Using just two basic valve housings – a straightway and an angle way – the platform offers five different functions. You will find that this simplicity offers you easy and time-saving usage in many processes.
Danfoss Flexline™ products offer an easy road to sustainability with low life-cycle costs, low emissions from leaks and approvals for use with low GWP refrigerants.
