Scroll Compressors

When Emerson first pioneered the use of scroll technology in compressors, it changed the industry forever. Since then, Copeland Scroll technology remains at the forefront for HVACR applications, impressing contractors and original equipment manufacturers (OEMs) with its superior efficiency, proven reliability and ease of installation.

Approximately 35 percent of the electrical energy consumed each year in the United States is used by HVACR systems. Compressors make up a vast majority of the energy used in air conditioning and refrigeration systems. That means compressor selection is key to improving the overall efficiency of HVACR systems. The inherent design of Copeland Scroll compressors makes them a preferred choice for more energy-efficient systems. In fact, Copeland Scroll compressors play a key role in helping the industry throught major transitions like the 1992 move to a 10 SEER standard and the industry's shift in 2006 to a 13 SEER minimum. As the industry prepares for another regulatory change - this time the phaseout of R-22 refrigerants in favor of the more environmentally friendly R-410A - it will benefit from the versatility and efficiency of scroll compressor technology.

As the industry transitions from R-22 refrigerants to the more environmentally friendly R-410A, a surprising event has occured. Adoption is taking place faster than anticipated. In fact, the market is already 50 percent higher in R-410A than expected. With nearly 10 million Copeland Scroll R-410A compressors installed worldwide, we have the industry's broadest line of environmentally friendly R-410A compressors.

Copeland Scroll compressors are known for their reliability because of theirPatented design features including:
  • 70 percent fewer moving parts
  • Ability to start under any system load, without start components
  • Compact, light-weight design
  • No complex internal suction and discharge valves for quieter operation and higher reliability
With the broadest product line in the industry, Copeland Scroll compressors range from1-60 HP and are installed in more than100 million installations around the world. They have become the compressor of choice to lead the industry through major transitions, including the13 SEER minimum-efficiency requirement and R-22 phaseout. Copeland Scroll compressors can be used in single or tandem configurations and can also be modulated for increased efficiency and homeowner comfort.

Design Benefits
Better Liquid Handling
Axial and radial compliance allow the scroll members to separate in the presence of liquid refrigerant, thus, providing protection against liquid damage
Greater Efficiency
More efficient over their entire operating range
Improved Sound
Operate at lower sound and vibration levels than traditional compressors
Unmatched Reliability
  • Easy to service and maintain due to their compact size and lightweight, simple design
  • Engineered for optimum performance with today's chlorine-free refrigerants
