Liquid = bubble (use for subcooling). Vapor = dew (use for superheat). Bold rows: 4 °C and 38 °C. Reference only: always verify with the manufacturer’s data and your gauges.

How to use

Choose Temperature or Pressure and type the number. The answer shows straight away.
Blends show two values: use vapor (dew) for superheat and liquid (bubble) for subcooling.
Tap °C · kPa for metric. Below 0 psig, pressure is in inches of mercury (inHg) vacuum.
Press Print pocket chart for a one-page chart (Letter or A4) for the van or the tool bag.

About this R-507A chart

This R-507A pressure temperature chart gives the saturation pressure for every degree, in psig with °F or kPa (gauge) with °C. As a blend, it has a liquid (bubble) and a vapor (dew) column.

Source: manufacturer and supplier charts (Chemours, Honeywell, Arkema, A-Gas). Reference only: always verify with the manufacturer’s data and your gauges.

FAQ

What is the R-507A pressure at 40 °F?

89.2 psig vapor (dew) and 89.2 psig liquid (bubble) at saturation, from the table above.

What is the R-507A pressure at 100 °F?

242.1 psig vapor (dew) and 242.3 psig liquid (bubble) at saturation.

Why does R-507A have two columns?

R-507A is a blend with very little glide (0.04 °F), so liquid (bubble) and vapor (dew) are almost the same. Use vapor for superheat and liquid for subcooling.
