Solstice N15 (R-515B) is a nonflammable azeotropic blend designed for chillers, heat pumps and high-ambient air conditioning systems.
With a GWP of 293 (4th IPCC), this hydrofluoroolefin (HFO) blend demonstrates environmental and performance benefits in new systems whilst its similar product design to R1234ze provides a long-term solution that is suitable for both A1 and A2L refrigerants.
