Semi-Hermetic Compressors

Copeland Discus Delivers Best in Class Performance

Copeland Discus compressors have been the unquestioned leader in commercial refrigeration for over 25 years. Combining world class efficiency and reliability, Discus is the compressor of choice to meet your refrigeration needs. The unique Discus valve design provides improved efficiency at operating conditions where most semi-hermetic compressors run. Grueling life testing and 25 years of field experience make Discus compressors the most reliable compressor in the industry.

Continued Technology Leadership on the Discus Platform

Emerson Climate Technologies engineers have continued to develop new and exciting technologies to leverage the established Discus platform. One example stems from the challenge end users have always faced with the ability to match compressor capacity to the load requirements of the refrigerated space. Copeland Discus Digital compressors were designed to specifically meet that challenge. With the ability to modulate infinitely between 10-100% of rated capacity, Discus Digital compressors match the system load requirements precisely while consuming less energy and increasing the life of compressor and other system components.

Protect Your Investment with Copeland Discus Compressors

End users want cold and they want it reliably. Even the most robust industry leading compressors, such as Discus, can fail or not function properly under adverse conditions, like poor installations. Facing this challenge, Emerson Climate Technologies engineers have developed innovative technologies via compressor electronics to increase compressor reliability and life. All new Discus compressors are shipped with CoreSense technology onboard. Through innovative and proprietary algorithms the compressor is used as a sensor to protect and diagnose the compressor. When adverse conditions exist, CoreSense technology can proactively shut down the compressor to prevent future damage until the condition is no longer present, enabling longer compressor life and sustained product integrity while protecting the refrigeration investment.
