Forane 407a r 407a is a non ozone depleting zeotropic blend of hfc refrigerants r 32 r 125 and r 134a. So when the refrigerant type is not specified or required by specification please indicate r410a.

Consult your copeland wholesaler for the proper part. R 407c pressure temperature chart n. Freon 407a r 407a refrigerant is a reliable stable and nonflammable option for low and medium temperature refrigeration systems. If your system has moduload the valve plate assembly must be changed.

R 404a rose to prominence in the late 1990 s with the phasing out of cfc and hcfc refrigerants like r 12 and r 502. Red italics indicate inches of mercury below atmospheric pressure saturation pressure temperature data for r407a psig. 404a s reign however was short lived.
