R1233zd(E) pressure temperature chart (PT)
R1233zd(E) saturation pressure vs temperature (PT chart): a CoolProp-generated reference table in kPa(a), bar(a), and psi(a), plus safe interpretation notes (not diagnostic targets).
An R1233zd(E) pressure temperature chart (PT chart) is a saturation lookup for R1233zd(E): it relates temperature and saturation pressure when liquid and vapor coexist in equilibrium. This is useful for thermodynamic interpretation, but it is not a universal "normal running pressure" diagnostic chart.
Pressure basis: absolute vs gauge
The table below is absolute pressure (kPa(a), bar(a), psi(a)). Many gauges display gauge pressure (relative to ambient). Converting requires local atmospheric pressure:
Pabs = Pgauge + Patm

Safety note
Refrigerants have safety classifications (toxicity/flammability) and their use is governed by codes and local regulations. This page is educational and provides property reference data only -- always follow OEM procedures and applicable safety requirements.
R1233zd(E) saturation pressure vs temperature (reference table)
Generated using CoolProp (the same property engine used by FluidTool) at Q=0 saturation. Values are rounded for readability.

How to verify any row in FluidTool
- Open FluidTool with R1233zd(E) selected: /?fluid=R1233zd(E)
- Choose a Two-phase input pair (Temperature & Quality / T + Q).
- Set Q=0 and enter the temperature from the table to read Psat.
