Product Data Summary and Thermodynamic Tables.Discharge Pressure +15 to +25 psi Cooling Capacity -2 to +2% Discharge Temperature -10 to -15 °F (-23.3 to -26.1 °C) Energy Efficiency Depends on equipment design; but, will be very similar to R-22 Will R-407C systems have different components than R-22 systems? Although the operating characteristics of R-407C are veryThe R-407C refrigerant consists of three HFC (hydrofluorocarbons) components. They include R-32 (difluoromethane), R-125 (Pentafluoromethane), and R134A, also known as 1, 1, 1, 2- tetrafluoroethane. Additionally, the refrigerant is environmentally friendly since it has a Global Warming Potential of 1774 and a zero …Most of you know R-32 as a necessary component in the widely popular HFC blend known as R-410A Puron. R-32 along with R-125 gets you that R-410A that is found in nearly every air conditioner today. However, in recent years there has been a push to slowly phase down R-410A. That is because of 410A's very high Global Warming Potential, or GWP.Liquid Pressure: 356.5 PSIG. Vapor Pressure: 116.1 PSIG. It should be noted that when using a zeotropic refrigerant (any refrigerant made up of two or more different types of refrigerants, each with different boiling points), care should be taken to observe the bubble point and dew point.It is the instructions to charge with the original R22 and has the charging charts if you want/need to switch an alternate suitable/approved gas. You will need to know the sea water temperature and the cabin air temperature as well as the high and low pressures. This site site will not let me attach a file that large.
