Solstice® 513A (R-513A)

Solstice® 513A is a non-ozone depleting, low global warming potential (GWP) hydrofluoroolefin (HFO)- based refrigerant developed to replace R-134a in positive displacement, direct expansion, medium-temperature commercial and industrial chillers, as well as flooded and/ or centrifugal chillers. Solstice 513A is an excellent capacity and efficiency match for R-134a in new systems, as well as for retrofit of existing systems, offering an optimal balance of properties including high energy efficiency and lower GWP, which is better for the environment.
