DuPont Refrigerants has provided cooling solutions for air conditioning and refrigeration applications since the beginning of modern-day supermarkets.

Supermarkets are facing increasing pressure to reduce their environmental footprint by moving refrigeration equipment away from ozone-depleting HCFC refrigerants. R-22 is subject to phaseout as an HCFC under the Montreal Protocol. Please read the file (U.S. only), U.S. R-22 Outlook: The time to act is now to transition from R-22, to learn about the reasons why it is important for you to plan now for changes in refrigeration and air conditioning.
