Purple Coil Detail

R-134a SI Detailed Chart — Purple Coil Detail

A copper coil contrasts with the purple header, with a white reference-state strip above three Celsius table blocks.

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 purple coil detail version covers -20 to 60°C in 1°C steps.

The strip above the table highlights the same reference state in temperature, psi gauge pressure, and bar gauge pressure for a quick unit comparison. The 81 listed reference points use Celsius, bar gauge, kPa absolute.

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.
