Emerson, St. Louis, Mo., expanded its Copeland Discus III compressor line with new 4DA/4DE and 6DU/6DV/6DZ models.

The 4DA/4DE models are Copeland’s smallest capacity 4-cylinder Discus compressors, targeted toward foodservice and food retail applications such as condensing units, supermarket racks, environmental chambers and process chillers.

Meanwhile, the 6DU/6DV/6DZ models are Copeland’s largest capacity 6-cylinder Discus compressors intended for use in the foodservice and food retail space as well as scientific plants and laboratories. These models increase the 6-cylinder capacity by more than 20%, offering a significant capacity increase without increasing footprint.

With CoreSense technology, every Discus model is equipped with oil pressure, motor and discharge temperature protection as well as easily accessible fault information and LEDs for clear visual indication of faults. Operators can also obtain enhanced diagnostics and protection via advanced current-sensing algorithms.
