About Scroll Compressors
TestEquity Model 1027S, 1027C, and 3007C 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.
Copeland Scroll compressors are the most reliable compressors available.

Copeland Scroll compressors achieve high efficiencies due to 100% volumetric
efficiency during the compression process. Their patented scroll design operates
under continuous flank contact, maintained by centrifugal force. This minimizes
gas leakage and maximizes efficiency.

Reduced Sound Level
Copeland Scroll compressors function with fewer moving parts, and no discharge
or intake valves. The scroll design allows several pockets of gas to be compressed
simultaneously providing a smooth, nearly continuous compression cycle. This
enables the Copeland Scroll compressor to operate more smoothly and quietly,
with less vibration.

How a Scroll Compressor Works
Unlike reciprocating technology with many moving parts, the Copeland scroll
compressor has one scroll or spiral orbiting in path defined by a matching
fixed scroll. The fixed scroll is attached to the compressor body. The orbiting
scroll is couple to the crankshaft in orbit rather then rotated. The orbiting
motion creates a series of gas pockets traveling between the two scrolls. On
the outer portion of the scroll the pocket draw in gas, then move it to center
of the scroll where it’s discharged. As the gas moves in the increasing
smaller inner pocket, the temperature and pressure increase to the desired
