2.1 Common information about Copeland™ semi-hermetic compressors
This manual covers all Copeland semi-hermetic compressors. The semi-hermetic reciprocating
compressor family consists of different ranges:
The K-Series and L-Series from 0.5 hp to 4 hp are available as air-cooled or water-cooled
versions and use reed valve technology.
The S-Series includes models 2S, 3S, 4S, 6S and 8S. It is suction gas-cooled and ranges
from 5 hp to 70 hp. It uses reed valve technology and offers cost-effective solutions.
The Discus™ series includes models 2D, 3D, 4D, 6D and 8D and ranges from 4 hp to 60 hp.
Its optimized Discus™ valve plate design provides the highest energy efficiency.
Special applications are addressed with a selected range of 2-stage, Booster and tandem
compressors.
Copeland compressors are suitable for a wide range of applications either in the form of single
compressors, condensing units or as multi-compressor equipment.
The compressor is only one component which must be combined with many others to build a
functional and efficient refrigeration system. Therefore the information in this manual relates
to all semi-hermetic compressors with standard equipment and accessories only.
