The Copeland™ ZFW variable speed scroll solution includes brushless permanent magnet (BPM) motor-based scrolls and variable frequency drives (VFDs) targeted for low-temperature, stationary refrigeration applications. The variable speed scroll provides better efficiency, precision, flexibility and reliability, while Copeland variable frequency drives, EVM/EVH Series complement Emerson compressors and controls. It has double the capacity of a fixed-speed compressor of the same size while providing a 20–30% efficiency improvement. With vapor injection technology and a speed range of 1,000–7,000 rpm, it offers unparalleled levels of control, while reducing cycling rates and greatly improving reliability. Optimized for use with new Copeland EVM variable frequency drives, the combination offers cutting-edge levels of performance. While intended for compression, EVM drives are also universally applicable for fans, pumps and other electric motors. With Bluetooth capability, commissioning is more streamlined than ever. To optimize ease of use, the Copeland EVM has been preconfigured for Emerson controls (iPro, E2, E3, Site Supervisor) and can be integrated universally with any controller. Available today with A1 refrigerants and moving toward A2L approval by 2024, the platform offers a robust design option for complying with current and future commercial refrigeration regulations.
