Delivers unmatched energy efficiency:
5-20% Improvement
• Motor, scroll and bearing redesign minimize annual
energy consumption.
• Precision machined scrolls provide the highest isentropic
efficiency and wear-in for improved performance
over time.
• New valving technology adjusts the scroll compression
ratio based on operating condition, significantly
improving low ambient performance.
Superior reliability equipped with
™
CoreSense
• The Copeland Scroll compressor design has several
inherent reliability advantages:
- 70% fewer moving parts than reciprocating compressors
- Axial & radial scroll compliance provides improved
liquid handling capability
- Hermetic design reduces leak potential
• Redesigned suction gas flow results in lower oil circulation
and better motor cooling.
Diagnostics
• Using vapor injection improves system capacity by 50%
and efficiency by 20% on average at the low temperature
rating condition.
