USA: Emerson has announced the introduction of a family of Copeland variable frequency drives for commercial and industrial refrigeration applications.
Emerson says its Copeland VFDs are designed with contractor ease of installation and use as a top priority, with many features such as quick-start menus included to streamline commissioning and service. In addition, they are said to integrate seamlessly with Emerson’s legacy E2 supervisory control, new Lumity E3 supervisory control, and Dixell refrigeration controllers.
One VFD model can be applied to multiple compressors as well as general purpose motors, greatly reducing the need to stock many SKUs to apply toward a wide range of applications.
Two ranges are available – the EVM and the EVH series. Copeland EVM VFDs cover from ½ to 30 horsepower, have single and three-phase input options, and are simple to use with Bluetooth onboard connectivity. EVM VFDs are said to be well-suited for chillers, medical refrigeration, display cases, walk-ins, reach-ins and other applications where less control functionality is needed.
Copeland EVH VFDs cover from 1 to 250hp and all standard three-phase options, including 575V. They have expanded control to handle applications requiring more functionality, such as centralised rack applications, CO2 booster systems, advanced chillers and industrial refrigeration.
Copeland EVM and EVH software has been optimised for Copeland compressor compatibility, but also offers the same functionalities commonly found in other industrial drives of competitive offerings. The VFD platform covers all Copeland compressors, including scroll, semi-hermetic and screw compression technologies.
