The Orbia Fluor & Energy Materials Klea Edge R-444A is an economically priced, low-GWP refrigerant that is a direct replacement for R-1234yf.  Independent test data confirms faster pulldown times and superior cooling, according to the company.  With a best-in-class energy efficiency up to 10 percent higher than R-1234yf, R-444A improves fuel economy or EV driving range, while delivering colder air faster than incumbent refrigerants; all while meeting strict GWP targets and having zero ozone depletion potential (ODP). Rated A2L by ASHRAE/ISO, the same as R-1234yf, retrofitting for R-444A can occur without major system overhauls using common A/C service tools.
