Benefits of Copeland scroll compressors:
Only three moving parts--fewer moving parts means less maintenance needed. By contrast, other reciprocating compressors can have up to nine moving parts in each cylinder.
No complex internal valves--the simplified design resists liquid refrigerant slugging, debris and failure,
Higher efficiency--Copeland was one of the first companies to create partial load operation across its compressor line. Their scroll compressors tend to be more efficient across its entire operating range.
Lower vibration levels--this means not just less noise, but also less wear and tear on components.
