![]() Now that I have indicated that, it relieves a lot of pressure. Psia is absolute pressure, which means it is gauge pressure + 14.7 psi. Psig (inches of mercury) is equal to psia – 14.7 at sea level. Let’s take a look at our pressure chart below. In the off chance that you do come across a R-502 application then you will need to know the pressures. R-502 PT Chart Showing 1 to 37 of 37 entries Previous NextThe most common replacement refrigerant was the HFC R-404A, but now even 404A is being phased out due to it’s high Global Warming Potential. ![]() For on-site use, we include a printable …The most common replacement refrigerant was the HFC R-404A, but now even 404A is being phased out due to it’s high Global Warming Potential. Note: R134A is chemically named 1,1,1,2-Tetrafluoroethane. That’s very practical we always use a pressure gauge meter when measuring the pressure in refrigerant lines. The pressures in the PT chart are expressed in psig or gauge pressure.

Vapors, in case of leakage tend to accumulate at ground level. R-404A containers should be stored in a cool and ventilated area away from heat sources. AEL (Allowable Exposure Limit) is 1000 ppm (8-hour TWA). 3985.Toxicity of R-404A is very low even with long exposure time.
