407c Operating Pressures, It is chemically stable, has good thermodynamic properties, low environmental impact and Refrigerant Guys PT – Chart R407C *Red Italics Indicate Inches of Mercury Below Atmospheric Pressure The pressure-temperature chart for R407C is a graphical representation that shows the relationship between the saturation pressure and temperature of the refrigerant. R407C Pressure Temperature Chart R407C Pressure Temperature Chart The information contained within this website is for guidance only, for further system specific advice please call A R-407C has the closest capacity match to R-22 of any of the retrofit blends. Below, you will find an Example: Find the amount of subcooling on a system using Genetron R-407C when the liquid line temperature reads 85°F and the liquid line pressure is 200 psig. To ensure the reliable operation of the refrigerant R407C in coun-tries with high ambient temperatures of up to 50°C, Bock compres-sors for R407C are approved for a maximum operating pressure of 35 FreonTM 407C and FreonTM 407A Refrigerant Descriptions FreonTM 407C and FreonTM 407A are non-ozone depleting blends of three hydrofluorocarbon (HFC) refrigerants.
