DUPREX 3.0 - DuPont Refrigerant Expert™

What is DUPREX 3.0?

DUPREX 3.0 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

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

DUPREX 3.0 is available in:

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

The Benefits of DUPREX 3.0

• Single source for fluorocarbon 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
  

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