Emerson Climate Technologies’ New Transcritical Compressors Receive Recognition from Underwriters Laboratories (UL)

New semi-hermetic line uses natural CO2 as its refrigerant, virtually eliminating its Global Warming Potential (GWP)

ST. LOUIS, January 27, 2013 — Emerson Climate Technologies, Inc., a business of Emerson (NYSE: EMR), today announced it has received Underwriters Laboratories (UL) recognition for its new line of semi-hermetic compressors. The new line of reciprocating compressors utilizes CO2 as its refrigerant, virtually eliminating its Global Warming Potential (GWP).

This new design is currently available in 12, 15, and 28 HP sizes, allowing it to be used in a variety of applications, such as grocery stores and supermarkets.

UL recognition is critically important in the refrigeration industry as it identifies compressors that meet global safety standards, ensuring products have been thoroughly tested and achieve a pre-determined set of international performance guidelines.

“For those customers who want compressors that use a natural refrigerant, Emerson’s new line of compressors are one of only a handful of transcritical units that have received UL recognition,” said Mitch Knapke, market manager, food retail, Emerson Climate Technologies. “And because CO2 runs hotter than other refrigerants, it becomes an excellent candidate for use in heat recovery.”

Transcritical compressors are the next step in the evolution of semi-hermetic designs. Similar to subcritical compressors, transcritical compressors can be used for both low- and medium-temperature applications, but without the limitations of requiring the refrigerant go through a phase change from liquid to gas.

Emerson has marketed transcritical compressors using natural refrigerants in Europe since January 2012. For more information about Emerson’s new line of transcritical compressors, please visit www.emersonclimate.com.
