We've taken the traditional paper P/T chart you've relied on for so many years and adapted it for the technology of today. The DuPont Pressure-Temperature calculator mobile app gives HVACR service technicians handy and accurate refrigerant data on the go, enabling quick and reliable systems diagnostics and response. Refrigerant options on the app include all major refrigerant products including DuPont(TM) Freon(R) 22 and Freon(R) 12, as well as their common replacements like DuPont(TM) SUVA(R) 410A, 404A, and DuPont(TM) ISCEON(R) MO99(TM) refrigerants. Data available for each refrigerant includes: % composition, physical, chemical, environmental properties, temperature glide, typcial use applications and lubricant recommendations. The DuPont PT calc will display the corresponding pressure when a temperature is input or provide the temperature for a given pressure reading. For refrigerant blends, both the saturated vapor and saturated liquid values are provided. The user can specify the data in either English or metric units. In addition the DuPont PT calc also quickly calculates the superheat and/or subcooling from an operating system based on input from the service contractor in the field, allowing quick and accurate charging, start up, and/or troubleshooting HVAC systems. This is a free app from DuPont Refrigerants.
