## What is EdgeSpace HVAC PT Chart?

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.
