ZR COPELAND SCROLL™ COMPRESSORS Copeland 1 PRODUCT DESCRIPTION Until a few years ago, the problems of complex part geometries and precise tolerance requirements made scroll technology impossible to manufacture in high volumes at low costs. But after a ten-year effort, Copeland Corporation developed design and manufacturing technologies that solved these problems. Copeland achieved two major breakthroughs: the Copeland Scroll ™ and the exclusive manufacturing process required to produce this compliant scroll compressor. Compliance refers to the method in which the two scroll members interact to achieve high efficiency and durability simultaneously. Copeland's unique and patented approach, achieving both radial and axial compliance, has several advantages: • 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, eliminating high stress in the members and substantially improving durability of the compressor. • Axial compliance allows the scroll tips to remain in continuous contact in all normal operating conditions, ensuring minimal leakage . . . without the use of tip seals. Copeland Scroll performance will not degrade over time because there are no seals to wear and cause gas leakage. In fact, over time, the compressor's performance improves as the scrolls wear-in. Because of its compliant feature, Copeland's scroll has unprecedented liquid-handling capability. No accumulator or crankcase heater is required in most system applications. In addition, it is designed to start under any system load. This feature eliminates the need for start kits. Combined, these characteristics simplify system design and increase system reliability. Model selections, electrical choices and operating conditions can be found in the pages that follow. This 60 hertz book should better assist you with your final product selection. Copeland Corporation has a reputation for quality and technology leadership that has been earned through years of performance. Copeland has more than 5,000 employees around the world working to ensure the reliability of its products. At 20 manufacturing facilities in eleven countries, Copeland goes about its only business – making compressors. These efforts assure our customers they are purchasing the most advanced compressor products that are backed by Copeland quality.
