Common information about Copeland Scroll compressors
The Scroll compressor has been under development at Emerson since 1979. It is the most efficient
and durable compressor Emerson has ever developed for air conditioning, refrigeration and
heating applications.
These application guidelines deal with vertical single Copeland Scroll compressors
ZB50KCE to ZB114KCE & ZB66K5E to ZB114K5E for medium temperature refrigeration
applications, and ZF25K5E to ZF54K5E for low temperature refrigeration applications.
These compressors have one scroll compression set driven by a three-phase induction motor.
The scroll set is mounted at the upper end of the rotor shaft of the motor. The rotor shaft axis is in
the vertical plane.
