Blue Molecular Medallion

R-134a SI Detailed Chart — Blue Molecular Medallion

A ball-and-stick medallion sits on a blue-to-teal heading above a dense multi-unit Celsius table.

Use this sheet when you need an R-134a reference at 1°C intervals. Read across a Celsius row to compare gauge pressure in bar with absolute pressure in kPa; those pressure columns use different reference points. This blue molecular medallion version covers -20 to 60°C in 1°C steps.

This multi-unit version includes additional pressure columns, allowing the same saturation row to be compared across more unit systems. The 81 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.
