Suva® 95 refrigerant
DuPont™ Suva® 95, a PFC-based refrigerant, is the industry standard replacement for R-13 and R-503 in very low temperature applications [below -40°F to -150°F (-40°C to -101°C)] 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® 95 can be used in new equipment and can also be used to retrofit existing systems.
