Commercial Refrigeration Compressors from Emerson Climate Technologies Designed to Meet New EPA Compliance Standards

ST. LOUIS, July 28, 2016 — With the commercial refrigeration industry taking a closer look at natural and alternative refrigerant options in the wake of the Significant New Alternatives Policy (SNAP) program set forth by the Environmental Protection Agency (EPA), Emerson Climate Technologies, Inc., a company of Emerson (NYSE: EMR), has updated its Copeland compressor lines to meet these new compliance standards.

The refrigeration industry is taking an even closer look at both CO2 (R-744) and propane (R-290); each has extremely low global warming potential.

In one back-to-back R-290 performance testing, Emerson saw an efficiency improvement of approximately 10 percent. Several compressors that utilize these natural alternatives have been released, including:
•Copeland semi-hermetic transcritical CO2 compressors
•Copeland Scroll™ compressors for subcritical CO2 applications
•Copeland hermetic compressors for R-290 to be used in small reach-in systems where the refrigerant charge is less than 150g

The majority of Copeland compressor platforms have also been validated for use with A1, hydrofluoroolefin blends, such as R-448A and R-449A. This includes both the Copeland Scroll and Copeland Discus™ semi-hermetic compressor lines. Later this year Emerson expects to validate its line of Copeland hermetic compressors for use with these blends as well.

Emerson has also invested in compressor evaluations using A2L (mildly flammable) refrigerants such as HFO-1234yf and HFO-1234ze. While the EPA has not yet listed A2Ls as an acceptable substitute, Emerson is preparing for their likely introduction into commercial refrigeration applications.


“It’s important to note that from a refrigerant perspective we’re not changing our core technology to achieve compatibility. We are continually improving our designs to optimize new refrigerant alternatives,” said Kurt Knapke, vice president, engineering and electronics, Emerson Climate Technologies.
