Liq = liquid (bubble) (use for subcooling). Vap = vapor (dew) (use for superheat). Italic " = inches of mercury vacuum. Bold rows: 40 °F and 100 °F. Reference only: always verify with the manufacturer’s data and your gauges.
How to use
- Tick the refrigerants you work with, up to 6.
- Pick °F · psig or °C · kPa.
- Press Print chart. It fits one landscape page, Letter or A4. Laminate it or keep it in the van.
A PT card for the tool bag
Supply houses don’t hand out fold-out PT cards like they used to, so make your own. The °F chart lists every 2 °F from −40 to 150 °F; the °C chart lists every degree from −40 to 65 °C. Blends get a liquid and a vapor column. For every single degree, use the chart page for that refrigerant.
FAQ
Why only 6 refrigerants?
More columns would make the print too small to read on one page.
Can I print a full chart for one refrigerant?
Yes. Open its PT chart page and press Print pocket chart for every degree on one page.
