EdgeSpace HVAC PT Chart

Field PT chart: R-410A & more. Psig/kPa / °F/°C, glide notes, dual-scale chart. Offline — $4.99, no ads.

EdgeSpace HVAC PT Chart is an offline saturation pressure–temperature lookup for HVAC technicians — not a BTU or load calculator.

Pick a refrigerant (R-410A, R-22, R-134a, R-32, R-404A, R-407C), enter gauge pressure (psig / kPa / bar) or temperature (°F / °C), and read bubble and dew saturation values plus glide for zeotropes. Dual-scale chart, PDF snapshot, history, and favorites.

Saturation ancillaries are from the open CoolProp fluid library (MIT) with EOS citations on each fluid — not scraped manufacturer pocket charts.

WHAT YOU GET • Pressure → saturation temperature (and reverse) • Bubble / dew for blends with glide notes • Dual-scale PT chart view • Share, copy, and PDF • History and favorites • Fully offline — no account, no ads, no subscription

Approximate field reference. Verify with manufacturer PT chart and gauges. Not for charging by guess.
