Solstice® 452A (R-452A)

Solstice® 452A (R-452A) is a non-ozone-depleting, nonflammable, zeotropic blend designed to serve as a lower global-warming-potential (GWP) alternative to R-404A and R-507 for low- and medium-temperature applications in existing and new systems. A key feature of Solstice 452A is its matched compressor discharge temperature of R-404A and R-507 at both low- and medium-temperature conditions, helping to further minimize application and retrofit costs. Plus, it provides a close capacity match to R-404A and similar energy efficiency.

Solstice 452A is an excellent refrigerant option for direct expansion of refrigeration low- and medium-temperature applications, including commercial and industrial refrigeration, condensing units, plug-ins and transport refrigeration like trucks and trailers, powered vans or reefer containers. With 45% GWP reduction (IPCC 4) and close performance to R-404A, end-users can combine the same capacity and efficiency with more sustainable performance and lower environmental impact. In transport refrigeration, according to end users, R-452A has the same cooling capacity, fuel efficiency, reliability and refrigerant charge as R-404A.*
