EPA AIM Proposed Rule

This video discusses the latest EPA AIM proposed rule.

Navigating and staying compliant with all of the new retail and commercial refrigeration regulations can seem daunting…

Many of the hydrofluorocarbon (HFC) refrigerants used in commercial refrigeration produce environmentally harmful carbon emissions. As the industry looks for alternative refrigerants with lower global warming potential (GWP) and ozone depletion potential (ODP), questions arise concerning regulatory changes, refrigerant performance and safety. Don’t worry, Hillphoenix offers refrigeration expertise and solutions that satisfy the regulatory needs of today and tomorrow.

The information below offers an overview of important regulations, effective dates, and agencies involved. Links are also provided for additional information on specific regulations. If you have questions, email us at or call us at 770-285-3264.
