The concept of
compressing a gas by turning one involute form – or “scroll”
– against another around a common axis is nearly a century
old. It wasn’t until the late 1980s, however that one
company – Copeland – turned theory into practical reality,
using sophisticated, computer-assisted design and
manufacturing methods to achieve the critical tolerances
required. In the years since, Copeland has become the leader
in scroll compressor applications, with nine scroll
manufacturing facilities on three continents and millions of
units installed worldwide.
Copeland Scroll™
compressors employ two identical, concentric scrolls, one
inserted within the other. One scroll remains stationary as
the other orbits around it. This movement draws gas into the
compression chamber and moves it through successively
smaller “pockets” formed by the scroll’s rotation, until it
reaches maximum pressure at the center of the chamber.
There, it’s released through a discharge port in the fixed
scroll. During each orbit, several pockets are compressed
simultaneously, so operation is virtually continuous.
