EdgeSpace HVAC PT Chart
Pressure Temp Refrigerant
$4.99 · Designed for iPad. Not verified for macOS.
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.
