HVAC Refrigerant PT vs Mavens Tools

HVAC Refrigerant PT™ is the pressure–temperature reference built for working HVAC/R technicians and engineers. PT charts, superheat and subcooling calculations, and refrigerant data for 55 refrigerants — fast, accurate, and fully offline. No account, no ads, no internet required at the job site. PRESSURE–TEMPERATURE CHARTS Scroll or jump to any temperature and read saturation pressure instantly. Zeotropic blends show bubble (liquid) and dew (vapor) pressures side by side on the same line, so you charge and troubleshoot with the correct value — not an average. Temperature glide is right where you need it. SUPERHEAT & SUBCOOLING CALCULATOR Enter your gauge pressure and line temperature to get measured superheat or subcooling in seconds. For fixed-orifice systems, enter indoor wet-bulb and outdoor dry-bulb to get target superheat and a clear charge verdict. TXV/EEV systems check subcooling against the manufacturer's target. A reverse saturation lookup converts any pressure to its bubble and dew temperatures. REFRIGERANT DATA Every refrigerant includes classification, safety rating, cylinder color code, critical temperature and pressure, liquid and vapor density, specific heat, heat of vaporization, ozone depletion potential, GWP, common applications, and recommended lubricant. YOUR UNITS, YOUR STANDARDS Fahrenheit or Celsius. Seven pressure units: psig, psia, kPa, inHg, atm, bara, barg — matched to your gauges and local code. 55 REFRIGERANTS R-11, R-12, R-13, R-22, R-23, R-32, R-123, R-124, R-134a, R-290, R-401A, R-401B, R-402A, R-402B, R-403B, R-404A, R-407A, R-407C, R-407F, R-408A, R-409A, R-410A, R-414B, R-416A, R-417A, R-417C, R-422A, R-422B, R-422C, R-422D, R-427A, R-430A, R-431A, R-436A, R-438A, R-448A, R-449A, R-452A, R-452B, R-454B, R-454C, R-455A, R-500, R-502, R-503, R-507, R-508B, R-513A, R-514A, R-600a, R-717, R-744, R-1233zd, R-1234yf, R-1234ze From legacy CFCs and HCFCs for service work to today's low-GWP A2L refrigerants (R-32, R-454B, R-1234yf) and naturals (R-290 propane, R-717 ammonia, R-744 CO₂) — the refrigerants on your truck are in here.
