TestEquity Model 1027C and 1027S Temperature Chambers use Copeland Glacier™ Compliant Scroll® Compressors.

Copeland Corporation has long been the recognized world leader in scroll technology for air conditioning applications. This leadership role continues to expand, as Copeland is now the first U.S. manufacturer to introduce a scroll compressor line optimized for commercial refrigeration -- Glacier™ Compliant Scroll®.

With millions of installations and several scroll-dedicated manufacturing plants worldwide, Compliant Scroll® has proven to be the most reliable, most efficient and quietest compressor technology available today. Copeland's exclusive product design features both axial and radial compliance, which allows the compressor to be more tolerant of liquid refrigerant or debris. Compliant Scroll® compressors perform at higher efficiency levels than reciprocating compressors, and last longer over time. Copeland's scroll compressors have 50% fewer moving parts, which increases reliability and reduces sound levels. They also operate without suction valves, for added reliability and ease of maintenance.

How a Scroll Compressor Works

As the orbiting element contacts the stationary scroll, gas entering from the outside of the scroll is sealed by crescent shaped pockets that are formed. These pockets get smaller as they get closer to the center, compressing the gas continuously, until it is discharged through the center of the scroll.

• Continuous flank contact, maintained by centrifugal force, minimizes gas leakage and maximizes efficiency.
• Radial compliance allows the scroll members to separate in the presence of liquid refrigerant or debris, thereby substantially improving durability and reliability.
• Axial compliance allows the scroll to remain in continuous contact in all normal operating conditions, ensuring minimal leakage without the use of tip seals.
• Both radial and axial compliance allow the scroll members to actually "wear in" rather than wear out.

Copeland's Compliant Scroll® has unparalleled liquid-handling capability. In addition, it is designed to start under any system load. Combined, these characteristics simplify system design and increase system reliability.

Copeland's engineers have developed exclusive manufacturing processes required to produce the Compliant Scroll® compressor. And, Copeland has learned how to control the complex part geometries and precise tolerance requirements that make scroll compressor technology difficult to manufacture in high volumes at affordable costs. In designing the Compliant Scroll®, they developed proprietary computer models which result in optimum scroll geometry. Copeland engineers have also designed and developed advanced computer-controlled machinery to manufacture scroll forms cost effectively.
