Copeland ScrollTM
The Copeland ScrollTM compressor is the result of extensive research and development work that has been going on since 1979. This work has led to the production of the most advanced hermetic compressors currently available for air conditioning and heat pump applications in the 1.5 to 6.5 hp range. The Copeland ScrollTM compressors are manufactured in state-of-the-art factories in Belgium and Northern Ireland.

Why scroll compressors?
System manufacturers prefer scroll compressors over other technologies for the following 4 reasons:
Economy, reliability, durability and low noise levels.
High-efficiency compressors
The coefficient of performance (COP) values achieve up to 3.37 W/W under ARI conditions. This never before achieved
power efficiency is the result of
• a very high volumetric efficiency under all approved operating conditions as the tips and surfaces of the spiral largely avoid any dead space and re-expansion (no tip seals, effective axial and radial adaptation)
• minimised pressure losses due to a uniform seal in high speed operation as there is no valve plate
• reduced heat transfer losses due to improved separation of intake and pressurised gases.
Excellent noise values
The Copeland Compliant Scroll is the quietest compressor in its power range. Its noise level is 6 dB lower than that of the hermetic piston compressors:
• low operating noise as there are no pressure or intake valves
• minimal vibrations and pulsations due to a gentle and continuous seal resulting from the lack of abrupt piston movements.
Extreme reliability
This has been achieved by:
• a minimal number of moving parts
• tolerance for any liquids and particulate contaminants that get sucked in
• rigidly mounting the entire internal compressor
• low starting torque (unloaded start). A starting unit is not required for alternative current models.
• internal self-resetting temperature and current-sensitive motor protection on models ZR18K* ... ZR81K*
• protection against excessive pressurised gas temperatures (internal unit in models ZR18K* ... ZR81K*)
• the unique Compliance design means that the spiral surfaces adapt to each other and do not become out of phase.
