PT Lookup
v1

Select refrigerant, choose bubble/dew (for blends), enter pressure or temperature, and get an interpolated saturation value.

Data is loaded from /assets/pt/v1/…
Mode
Units here are gauge pressure (psig/kPa(g)) and temperature (°F/°C).
Curve (bubble/dew)
For blends, dew is often used for evaporator saturation and bubble for condenser saturation. OEM procedures come first.
Enter gauge pressure. If using vacuum (negative psig), enter a negative number.
Enter temperature in your chosen unit.
