Copper Molecular Medallion
R-134a SI Overview Chart — Copper Molecular Medallion
A molecular medallion fills the right side of the copper header above three blocks of multi-unit Celsius data.
Start with the Celsius column to find an R-134a saturation temperature, then read across for the equivalent Fahrenheit temperature and pressure. Its 2°C spacing is useful when you want a broad metric reference on one sheet. This copper molecular medallion version covers -40 to 80°C in 2°C steps.
This multi-unit version includes additional pressure columns, allowing the same saturation row to be compared across more unit systems. The 61 listed reference points use Celsius, Fahrenheit, bar gauge, psi gauge, kPa absolute.
Using this reference
The PDF preserves the one-page print layout. The matching Image is a full-resolution WebP rendering. These are finished reference sheets with fixed data and illustrations.
Gauge pressure uses a 101.325 kPa atmospheric reference. Saturation values describe the refrigerant relationship; equipment instructions determine operating and charging targets.
