Emerson Climate Technologies Completes Testing, Performance Ratings on R-448A/R-449A

Lower GWP refrigerants serve as alternatives to potentially banned R-404A and R-507A

ST. LOUIS, March 19, 2015 — Emerson Climate Technologies, Inc., a company of Emerson (NYSE: EMR), announced it has completed material compatibility testing, application guideline verifications, UL approval qualification and extensive life testing with both R-448A and R-449A. These refrigerants have a lower global warming potential (GWP) and serve as replacements for potentially banned refrigerants R-404A and R-507A, which are commonly used in supermarkets, condensing units and commercial refrigeration equipment.

The U.S. EPA has announced plans to transition new applications away from refrigerants with high GWP, such as R-404A and R-507A, as part of its Significant New Alternatives Policy (SNAP). SNAP works in conjunction with the president’s Climate Action Plan to reduce the use of hydrofluorocarbons with high global warming potential. The rule as proposed would ban R-404A and R-507A in specific new and retrofit applications by January 1, 2016.

“It is critical that our customers have tested, proven and sustainable alternatives to refrigerants that have been targeted for delisting,” said Mitch Knapke, director, food retail marketing, Emerson Climate Technologies. “To help our customers lessen the resource constraints and costs associated with a shift of this magnitude, we have been working to develop products and equipment that will not only comply with this delisting proposal, but also those in the foreseeable future.”

Performance ratings for these new refrigerants can be accessed in OPI software or through Emerson Climate Technologies’ Production Selection Software. Application guidelines are similar to R-407A and can be found online in the OPI software as well. Capacity and efficiency are also comparable to R-407A, showing ratings within 3 percent around the operating envelope. Discus and Copeland Scroll products are approved at this time, and small reciprocating hermetic compressors will be approved later in 2015.
