DuPont Refrigerant Expert™ (DUPREX)


What is DUPREX?

DUPREX Version 3.2 is a software tool from DuPont specifically developed to allow users to easily and quickly generate data for DuPont refrigerants, including:

  • thermodynamic properties
  • transport properties
  • theoretical refrigeration cycle calculations

Data can be calculated for a variety of direct expansion systems (single stage, single stage with internal heat exchanger, two stage cascade, and single stage heat pump).

DUPREX is available in:

  • 6 languages: English, German, French, Spanish, Italian, and Dutch
  • SI and ENG units of measure

What's New in DUPREX 3.2?

  • Updated to include ISCEON® MO99™ and ISCEON® MO49Plus™ refrigerants in Refrigerant selection menu.

  • Upgraded to include line sizing data in data generated for theoretical cycle calculations.

The Benefits of DUPREX 3.2

  • Single source for DuPont™ Suva®, ISCEON®, and Freon® refrigerant property data

  • Useful tool for assessing system performance with the most commonly used fluorocarbon refrigerants, including the extensive range of CFC and HCFC retrofit options available from DuPont Refrigerants

  • Facilitates quick and easy refrigerant selection at different operating conditions and system layouts for retrofit or new system design

  • Powerful system analysis tool to aid troubleshooting and diagnosis of system performance

  • Quick and easy tool to make multiple cycle calculations at various conditions

  • Generates custom thermodynamic and transport property data tables for specific projects or systems at defined saturated, superheat, and subcool ranges and intervals

  • Refrigeration cycle calculations consider compressor efficiencies, heat exchanger pressure drops, and suction line superheats to yield results that closely mimick actual systems

  • Theoretical cycle calculations include cycle properties and line sizing data

  • Program can be run from a memory stick for maximum convenience and flexibility
