R448A is an azeotropic mixture, which is classified as a non-flammable replacement refrigerant with a low GWP value. 10.2. R448A is not toxic or flammable (A1), and has zero ODP and a GWP of 1390. PHYSICAL PROPERTIES Solstice® N40 (R-448A) is a zeotropic blend designed to serve as a replacement for R-404A/R-507, R-22, R-407 series and interim It was designed to serve as a replacement for R404A (and R22) in low and medium temperature systems, such as refrigeration solutions in supermarkets and vending machines connected to the power grid and so on..

For example, HCFC-22 is an acceptable substitute for R-502 in industrial process refrigeration. R448A refrigerant is an excellent low-GWP, highly energy efficient and non-flammable refrigerant for low and medium temperature in commercial refrigeration: supermarket systems, vending machines (plug-ins) and other applications. Solstice™ N40 composition was slightly modified, and it was then designated as R448A. REACH Registration No. It has a GWP of 1273 and provides 68% GWP reduction compared to R404A. Solstice® N40 (R-448A) is a nonflammable, reduced-GWP HFO blend for new supermarkets or R-404A retrofits, especially low- and medium-temp refrigeration. 2,3,3,3-Tetrafluoropropene, HFO-1234yf, is a hydrofluoroolefin (HFO) with the formula C H 2 =CFCF 3.It is also designated R-1234yf as the first of a new class of refrigerants: it is marketed under the name Opteon YF by Chemours and as Solstice YF by Honeywell.. HFO-1234yf has a global warming potential (GWP) of less than 1, compared to 1,430 for R-134a and 1 for carbon dioxide. Trade name : R448A, Honeywell™ Solstice ® N40 ... Chemical name Chemical formula Concentration CAS -No. R448A, while the heat transfer coefficient for R452B was more than 59 % larger than either R448A or R449A. Other information Other information: R448A Relative Vapour Density 2.98 (Air=1) Section 10: Stability and reactivity 10.1. Chemical stability Chemical stability: Stable under normal conditions. Stable at room temperature. At first, Honeywell created Solstice™ N40, which is a blend based on R1234ze(E) . As predicted by the modified model, the heat transfer coefficients for R448A and R449A are roughly between 26 % and 48 % less than that of R404A for most qualities between 10 % and 70 %. EC No. The The following tables show the percentage composition of refrigerant blends found acceptable acceptableThis designation means that a substitute may be used, without restriction, to replace the relevant ODS within the end-use specified. … Reactivity Reactivity: Stable under recommended transport or storage conditions. REFRIGERANT R448A Page: 6 9.2. Various chemical companies have produced HFC-HFO blends to substitute R404A . R448A Thermodynamic & Transport Properties (Based on Venus model) Name Category Pure/Mixture Short Name Full Name Molecular Weight Critical Temperature . Composition (wt%) R-32/R-125/R-134a = 20/40/40.
