Emerson Climate Technologies Utilizes Environmentally-Friendly CO2 Refrigerant For Subcritical Refrigeration Applications

ST. LOUIS, April 14, 2008 – Emerson Climate Technologies, a business of Emerson (NYSE: EMR), announced today the launch of Copeland Scroll™ compressors designed for use with CO2 (Carbon Dioxide) refrigerant in low-temperature subcritical cascade cycle applications. The company is working with U.S. OEMs serving the supermarket refrigeration industry to test systems using the new Copeland Scroll compressors. Countries in Europe are increasing their usage of CO2 as a refrigerant due to its neutral impact on Global Warming and Ozone depletion, as well as harsher regulations than those in the United States on the use of other refrigerants.

“As a global company, we’ve kept a close watch on the use of CO2 as a refrigerant in refrigeration applications,” said Rajan Rajendran, director of applications engineering for Emerson Climate Technologies, Refrigeration Division. “For nearly all applications, we think the answer to minimizing environmental impact is still the use of high-efficiency equipment and the reduction of refrigerant leaks. HFC refrigerants often offer superior energy efficiency versus CO2. However, we are seeing that CO2 can offer comparable system efficiency when applied in a subcritical cascade refrigeration cycle, which can be applied in supermarket applications.”

Emerson Climate Technologies’ subcritical CO2 Copeland Scroll product line was previously launched in Europe to positive feedback. Emerson has received UL approval in the U.S. and is currently shipping samples and sharing product information with major U.S. supermarket OEMs and is working with retailers to test the CO2 systems.

The Copeland Scroll compressor is hermetically sealed, eliminating possible leak points found in reciprocating compressors (such as gaskets and bolted joints). This reduces the potential for direct refrigerant leaks. The compressor’s strong steel shell allows these compressors to withstand the high pressures associated with CO2 systems.

The most significant environmental impact of HVACR systems is derived from the byproducts of power generation needed to run the system. Also harmful are refrigerant leaks, a result of the lack of proper handling during service and disposal. These byproducts and leaked refrigerant play a role in Global Warming and Ozone depletion. A complete summary of the direct and indirect impact of different systems was detailed in a recent Emerson Climate Technologies webcast and can be viewed by visiting /refrigerant_webinar.htm.
