Emerson Approves R-407A for Copeland Scroll in Medium, Low Temp Apps
Sources from Emerson Climate Technologies Inc., a business of Emerson, announced on June 9 that Emerson has approved the use of R-407A refrigerant for Copeland Scroll® refrigeration compressors in medium- and low-temperature applications, per the approved operating range.

Emerson engineers also recently approved R-407A for Copeland Discus® compressors. The latest approval for Copeland Scroll refrigeration compressors offers another option to use R-407A refrigerant in OEM refrigeration equipment. "With the phase-out of R-22, the commercial refrigeration industry continues to explore alternative refrigerants," says Leland Smith, director refrigeration marketing, Emerson Climate Technologies.

For low-temperature operation at higher condensing temperatures, economized vapor injection (EVI) with demand cooling liquid injection is required with the use of R-407A for Copeland Scroll compressors. A demand cooling module kit is available for this purpose.
