The Copeland Discus Digital compressor is the latest addition to the Copeland Discus compressor family and is available for the three-cylinder Discus compressors. With continuous digital modulation from 10 percent to 100 percent, the compressor provides a precise method of capacity control, making it ideal for temperature-sensitive applications, according to representatives from Emerson Climate Technologies. The company also claims that introducing the Copeland Discus Digital compressors into a refrigeration system allows the system to specifically match the capacity being generated to the required load, providing the opportunity for the system to operate more efficiently, resulting in optimum system performance and control. The capacity modulation found in this compressor also reduces the suction pressure and temperature variation of the refrigerated space and provides a decrease in compressor cycling rates.
