R-1233zd(E) PT Chart

R-1233zd(E) saturation pressure, −40 to 150 °F−40 to 65 °C. Used in low-pressure centrifugal chillers.

Safety class A1Single component (HCFO)No glideNo glide

R-1233zd(E) runs below atmospheric pressure at normal chiller evaporator temperatures: the table shows 12.6 inHg vacuum at 40 °F, and 0 psig is not reached until about 65 °F. Values come from the table on this page.

Negative kPa = vacuum. Bold rows: 4 °C and 38 °C. Reference only: always verify with the manufacturer’s data and your gauges.

How to use

Choose Temperature or Pressure and type the number. The answer shows straight away.
Blends show two values: use vapor (dew) for superheat and liquid (bubble) for subcooling.
Tap °C · kPa for metric. Below 0 psig, pressure is in inches of mercury (inHg) vacuum.
Press Print pocket chart for a one-page chart (Letter or A4) for the van or the tool bag.

About this R-1233zd(E) chart

This R-1233zd(E) pressure temperature chart gives the saturation pressure for every degree, in psig with °F or kPa (gauge) with °C. Below 0 psig the °F table shows inches of mercury (inHg) vacuum.

Source: manufacturer and supplier charts (Arkema, A-Gas). Reference only: always verify with the manufacturer’s data and your gauges.

FAQ

What is the R-1233zd(E) pressure at 40 °F?

12.6 inHg vacuum at saturation, from the table above.

What is the R-1233zd(E) pressure at 100 °F?

14.5 psig at saturation.

Does R-1233zd(E) have glide?

No. R-1233zd(E) is a single-component refrigerant, so one saturation pressure works for both superheat and subcooling.
