Reliability  

Copeland Discus compressors are engineered for high quality and outstanding reliability.  Each Discus model series pass a grueling series of performance and durability tests.  This testing, combined with 20 years of real field experience, make the Discus an excellent choice for relibility.

Efficiency

Copeland Discus compressors have been the industry leaders in energy efficiency for the past 20 years. Patented Discus valve technology minimizes refrigerant re-expansion volume and is designed to meet a broad range of application requirements. It is the ideal choice for racks and single condensing units and is typically 10% more energy efficient than reed compressor technology.  

Compatability

Copeland Discus compressors perform in a variety of refrigeration application requirements from 50 degrees F down to -40 degrees F. The Discus compressor line offers a full range of 2 though 8 cylinder models that operate with a wide range of refrigerants.  

How it Works

The compression process begins with refrigerant entering the compressor through the service valve on the motor cover.  A precise quantity of the refrigeration (shown in red) is drawn through the motor to cool it for long life.  The remainder of the refrigerant flow (shown in orange) is routed outside the motor cavity to prevent absorption of heat, helping to optimize efficiency.

Another unique design feature of the Copeland Discus compressor is found in the valve plates. The patented Discus valve plate design allows gas to flow into the cylinders with a minimum amount of heat gain. The suction cavities are designed to smoothly route the gas to minimize turbulence. The puck-like Discus valve (shown in black) is the key to superior geometry and performance. Finally, compressed discharge gas (shown in red) flows through the cylinder head to exit.
