EMERSON Copeland Compressor Electronics Technology
The Copeland compressor electronics technology features a modular design with
a base board and plug-in modules with advanced functionalities.
Copeland compressor electronics is an innovative technology for Copeland
compressors to monitor and interpret data inside the compressor in order to
enhance the reliability and operational performance of HVACR systems.
Built upon the success of CoreSense Diagnostics introduced a few years ago,
Emerson is now introducing the Copeland compressor electronics for semi-
hermetic compressors featuring a modular design using state-of-the-art
electronics. This modular design with plug-in modules gives the customers the
flexibility to choose the advanced features as per their system requirements.
Benefits throughout the value chain
Copeland compressor electronics comes with a great set of features that offer benefits to refrigeration system manufacturers, service engineers and operators. The benefits of compressor electronics goes beyond compressor protection by assisting in system diagnosis and optimization. Providing service engineers with detailed information at the right time, system-related problems can be diagnosed faster or even before they occur.
Compressor electronics optional plug-in modules with advanced control features and factory mounted sensors reduce the system complexity and applied costs for system manufacturers. Supermarket operators benefit from increased system uptime, reduction in food loss and reduced maintenance costs. It is an opportunity for consultants to help their clients to be at the forefront of technology.
Helping manufacturers keep applied system costs under control
Copeland compressor electronics integrates many functionalities of modern
refrigeration systems directly into the compressor. A few examples of such
features include liquid injection control, dynamic envelope monitoring,
discharge gas temperature control, and digital modulation control.
Being able to talk to system controllers via the integrated Modbus® protocol and Bluetooth® for wireless communication, the need for installing sensor cables is greatly reduced. Compressor electronics technology accelerates system manufacturing and eliminates the potential manufacturing errors.
Copeland compressor electronics measures compressor internal data right at the
heart of the compressor.
It maintains a data and alarm history together with compressor asset
information such as model and serial number.
A simple LED on the compressor terminals box provides status information
through LED colour and flash codes and the compressor electronics software and
mobile app enable on-site diagnostic analysis. Information is maintained in
onboard EEPROM memory and can be downloaded on-site or remotely. With
compressor electronics, the compressor turns into a maintenance engineer’s
assistant.
Freeing end-users’ mind to focus on the strategic part of their business
Hard to believe that your operation would not benefit from reduced installed
system cost, predictive maintenance or a better understanding of the system’s
power consumption.
Connectivity has become essential in our personal lives and in commercial
applications. Compressor electronics Bluetooth® and Modbus® communication
options give end users peace of mind by making sure food
is protected around the clock. Compressor electronics power monitoring
provides the right tool to keep refrigeration system operational costs under
control.
Advanced protection and diagnostics capabilities help ensure system
reliability and reduce equipment downtime by guiding service technicians,
enabling a quicker troubleshooting in case of failures.
With Copeland™ compressor electronics, you enable the team that builds,
maintains and operates refrigeration system to leverage on the best available
compressor technology.
