Refrigerant PT Chart Saturation
Interactive refrigerant PT chart calculator for R-410A, R-32, R-134a, R-22, R-404A. Convert gauge PSI to saturation boiling temperature.
Technical Engineering Guide & Field Diagnostic Practices
A Pressure-Temperature (PT) chart is the foundational diagnostic tool for refrigeration engineers. By measuring operating gauge pressure at the suction and liquid service valves, technicians determine the exact boiling and condensing saturation temperatures inside the evaporator and condenser coils.
