Chemours Suva R95, a PFC-based refrigerant, is the industry standard replacement for R-13 and R-503 in very low temperature applications [below -40F to -150F (-40C to -101C)] such as medical freezers and environmental chambers. It offers advantages over R-23, including significantly lower compressor discharge temperatures, making it the best choice to ensure optimum systems reliability for critical applications. Suva R95 can be used in new equipment and can also be used to retrofit existing systems.
