Copeland Scroll™ Variable Speed Compressor for Commercial Applications

Breakthrough efficiency

Emerson’s Copeland Scroll™ variable speed compressors are designed to deliver maximum cooling and heating efficiency when you ​need it most. Whether designing for a roof-top unit in the United States or an air-cooled chiller in Europe or Asia, our latest variable speed compressor technology allows system manufacturers and building owners to achieve superior performance, including:

  • Expansive 1,500-7,200 RPM speed range for better light load efficiency and dehumidification
  • Highest part load efficiency in its class enabling significant energy savings and standards compliance
  • Capability to ‘tandemize’ for m​aximum flexibility in system design
  • Both compressor and drive are UL 60730 approved for reduced design time, cost, and speed to market
The unmatched efficiency of Copeland Scroll variable speed enables maximum efficiency

Proven Copeland Scroll™ Platform
– enhanced and optimized for variable speed
  • Optimized scroll elements for variable speed performance
  • Low oil circulation compressor plus scroll oil injection for low speed performance and reliability
  • BPM motor technology for highest efficiency
  • Sound reduction technology for reversible chiller transition and defrost

Expansive Control

The Copeland Scroll variable speed design enables system manufacturers, building owners, and contractors alike to experience a new level of control thanks to the following enhancements:
  • Expanded operating envelope providing the greatest flexibility in design and desired condition
  • Low turndown to 1500 RPM means less cycling for better dehumidification and light load efficiency
  • Enables precise temperature and humidity control across wide range of conditions
  • Proactive envelope control and resonance avoidance
  • AC drive controls motor stator heating thereby eliminating the need for a crankcase heater
Key Motor Drive Features
  • AC drive with optimized permanent magnet motor control for maximum performance and reliability
  • Dedicated compressor menu structure and parameters for quick and easy setup
  • Option range of multi-language click-in LCD keypads available for rapid set-up and superior diagnostics
  • RS485 Modbus® communications as standard
  • Slot for Smartcard / SD card for parameter cloning, storage, backup, and restore
  • Compact aluminum chassis allows flexible mounting, with built-in high performance extruded heat sink
  • System integration module slots for I/O, ethernet, and automation controller options

Comprehensive Protection

Copeland Scroll variable speed compressors take reliability to a new level with the integration of CoreSense™ technology. These active protection algorithms incorporated into the motor control drive safeguard the compressor and drive from many adverse operating conditions. The types of protection features include:
  • Motor & scroll temperature protection
  • Locked rotor detection
  • Phase protection and correction
  • Maximum operating current detection
  • Discharge line temperature protection
  • Anti-short cycling
This builds upon the reliability and proven performance from 25 years of scroll experience and more than 100 million installations around the world.
