What is the advantage of using Forane ® 427A instead of R-407C for the retrofit of existing R-22 equipment? When retrofitting existing R-22 equipment with Forane® 427A, an oil change is. R-427A is a zeotropic HFC blend which has been designed to replace R-22 (HCFC) by conversion of existing systems or for use in new systems. This means that Forane® 427A is non-toxic and non-flammable. Forane® 427-A – An Alternative To R-22. Just looking for some thoughts on the pro's and cons of each. Dew and bubble point is used only for calculation of superheat and subcooling. safety data sheets / r-427a. R407C, R427A and R438A emerged as most attractive substitutes. Freon™ Refrigerants. Forane 427A and R-407C are very close in composition, with R-427A having the addition of R-143a for enhanced oil compatibility. Its useful for very close targets where fast target acquisition is needed, just put the big circle on your target inside of like 25m and your good. It facilitates easy retrofitting in which the technician simply recovers the R-22, replaces critical seals, charges the Freon™ MO99™ refrigerant, and monitors for leaks. Forane® 427A has been assigned A1 safety classification by ASHRAE Standard 34. HCFCs Compounds containing hydrogen, fluorine, chlorine, and carbon atoms. Freon™ MO59 (R-417A) refrigerant is a hydrofluorocarbon (HFC) retrofit alternative for R-22 in direct expansion (DX) stationary air conditioning (AC) and medium-temperature commercial refrigeration systems. R407C is a zeotropic mixture of R32, R125, and R134a in an amount of 23%, 25%, and 52% respectively. In this series from Chadwell Supply and Chadwell University's Vann Flippen, walk through the refrigerants available to replace R22 and understand the pros an. superheat and subcooling: R-427A; R-508B (Suva95); R-407F; R-1234yf; R-417C (Hot Shot 2). The R-410A can work at higher pressures than the R-22. It is essential that blend refrigerants be charged by removing only liquid from the cylinder. According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined. Freon™ 407A (R-407A) refrigerant is a reliable, stable, and nonflammable option for low- and medium-temperature refrigeration systems. A condensing unit can have a significant impact on the productivity, reliability and energy efficiency of your building.
