Updated DuPrex 4.0 refrigerant comparison software

DuPont has now made an updated version of its DuPontâ„¢ Refrigerant Expert 4.0 (DuPrex 4.0) refrigerant comparison software available on the new Opteon® homepage to mark the sales launch of its new Opteon® product range.

Once a simple registration process has been completed at
, this free program enables rapid and effective comparison of numerous refrigerants in different refrigeration circuits in order to identify the best possible alternative for a particular application. In a world first for software of this kind, the program also contains new HFO-based refrigerant blends, such as Opteon® XP10, XP40 and XP44 together with the mildly flammable development products XL40 and XL41 which will be available in the near future. This will give users an insight into the next generation of refrigerants and enable longer term planning of applications.

Refrigeration service providers and operators can also find general information about the new refrigerants Opteon® XP10 (R-513A), XP40 (R-449A) and XP44 (R-452A) on the web page. These refrigerants  are suitable for retrofitting various stationary or transport refrigeration applications in which many currently used refrigerants, such as R-404A, are reaching the end of the road because of the European F-gases Regulation 517/2014. The new replacements have a particularly low GWP and allow simple conversion of existing systems, in many cases even with improved energy efficiency.

The web page also includes a directory of suppliers of Opteon® products, a summary of the European F-gases Regulation 517/2014, product specifications, conversion guidelines and reports describing successfully completed pilot projects.

DuPont (NYSE: DD) has been bringing world-class science and engineering to the global marketplace in the form of innovative products, materials, and services since 1802. The company believes that by collaborating with customers, governments, NGOs, and thought leaders we can help find solutions to such global challenges as providing enough healthy food for people everywhere, decreasing dependence on fossil fuels, and protecting life and the environment.
