Dew + Bubble
Pressure range (psig)
-54.6 to 138.3
Temperature range (°F)
-15 to 435
Note: PT points are stored in psig and °F. For blends, bubble and dew represent different saturation states. Always follow OEM charging procedures.
Quick actions
These routes are designed to be technician-friendly: minimal taps, prefilled context, and predictable URLs for bookmarks and sharing.
Pressure → Saturation temperature (quick)
Linear interpolation between nearest points. Out-of-range values show “—”.
| Pressure (psig) | Sat Temp (°F) | Source |
|---|---|---|
| 0 | 23.9 | linear |
| 25 | 57.1 | linear |
| 50 | 103.8 | linear |
| 75 | 167.5 | linear |
| 100 | 252.4 | linear |
Temperature → Saturation pressure (quick)
Useful for “I have a target saturation temp—what pressure should I see?” checks.
| Temp (°F) | Sat Pressure (psig) | Source |
|---|---|---|
| 0 | -27.2 | linear |
| 20 | -3.6 | linear |
| 40 | 13.4 | linear |
| 60 | 26.8 | linear |
| 80 | 38.2 | linear |
| 100 | 48.2 | linear |
| 120 | 57.1 | linear |
| 140 | 65.2 | linear |
