Emerson Climate Technologies has introduced a lineup of compressors aimed to help contractors and manufacturers provide the R-410A equipment needed to comply with the 2010 phase-out of ozone-depleting machines. The commercial Copeland Scroll compressor line was recently expanded to include 13- 15- and 30-horsepower models, fully optimized for use with R-410A. Copeland Scroll Digital is now available in R-410A models through 12 horsepower for commercial air-conditioning applications. Copeland Scroll Digital offers the ability to infinitely modulate compressor capacity from 10 to 100 percent and is ideal for commercial applications with widely varying loads or a need to maintain precise temperature and humidity control. The Emerson C-Series thermal expansion valve is designed for use in R-410A systems.
