Variable Speed Technology for Refrigeration Applications
Optimize performance, meet sustainability goals, and improve energy efficiencies with Copeland™ variable frequency drives and variable speed compression technologies.

The Copeland variable speed scroll compressors have double the capacity of a fixed speed compressor of the same size, while providing a 20–30% efficiency improvement. With a speed range of 1,000–7,000 rpm, it offers unparalleled levels of control, while reducing cycling rates and greatly improving reliability. With solutions for both low and medium-temperature applications, we are answering the call for more energy-efficient compression technology in the commercial refrigeration sector.
For OEMs of self-contained systems, meeting new design and sustainability requirements can present significant challenges. Achieving high energy efficiencies requires the use of large-capacity condenser coils that reduce available merchandising space. The placement of a standard vertical compressor can increase the case size, limit its aesthetic appeal, and create higher noise levels.
At roughly half the height of a vertical scroll, the low-profile Copeland horizontal variable speed scroll compressor solves known design challenges and represents the latest innovation in compliant scroll technology for refrigeration equipment.
The motor loads from heating, ventilation, air conditioning and refrigeration (HVACR) equipment are among the greatest consumers of electricity in the commercial building sector.
To reduce energy consumption and associated costs, building operators are installing Copeland variable frequency drives (VFDs) on their existing systems to deliver significant efficiency improvements and a quick return on investment (ROI). Copeland VFDs allow operators to retrofit their facilities by varying the motor speeds in fixed-speed HVACR motors – such as refrigeration compressors and evaporator/condenser fans.
Stand-alone commercial refrigeration equipment — such as medium- and low-temperature, reach-ins, walk-ins, food prep tables, and process chillers commonly used in restaurants, convenience stores (C-stores) and small-format food retailers — has been subjected to increasingly stringent energy requirements over the last decade.
Copeland variable speed reciprocating hermetic compressors are designed to deliver significant efficiency and performance improvements. Our variable solution is comprised of a Copeland variable speed reciprocating hermetic compressor and a variable speed drive with an embedded smart controller.
The Copeland horizontal variable speed scroll compressor has been recognized as a finalist in the annual AHR Expo Innovation Awards. This competition honors the most inventive HVACR products, systems and technologies.
