Copeland Discus Digital

Copeland Discus DigtalIn refrigeration applications, the quality of the end product is maintained by precisely controlling the temperature. However, the traditional technology requires compressor cycling and can lead to problems, including uneven cooling and reduced compressor life. That is why Emerson Climate Technologies developed the Copeland Discus DigitalTM compressor.

With the Copeland Discus Digital compressor, there is no compression taking place during the modulation off cycle; it allows the motor to move the crankshaft without any thermodynamic work, which in turn reduces power consumption up to 10%.

Copeland Discus Digital is the opportunity for wholesalers to retrofit rack and single compressor application with a new Discus Digital compressor or retrofit kit. Copeland Discus Digital is currently available in 3D with future plans to expand to other models.

More Information

Copeland Scroll ZRK5 Compressor

The Copeland Scroll® ZRK5 compressor has been designed for residential and light commercial air conditioning applications. With the addition of the ZRK5 compressor comes a replacement compressor built upon the quality and established scroll technology that only Copeland Scroll technology can deliver. The Copeland Scroll ZRK5 compressor includes 20 new design enhancements that provide enhanced temperature control and improved efficiency, which adds expert reliability and performance you can rely on.
Copeland Scroll Compressor

  1. Temperature operated disc – features a bimetallic disc that senses discharge temperature and opens at approximately 270 degrees Fahrenheit internal plenum temperature.
  2. Internal pressure relief – opens at approximately 400+/-50 pounds differential.
  3. Floating seal – separates the high side from the low side and also prevents the compressor from drawing into a vacuum, damaging the electrical terminal.
  4. Internal motor protector – senses both internal temperature and amperage. A tripped motor protector will exhibit a high shell temperature. Allow the compressor to cool to reset the motor protector.

Copeland Scroll ZRK5 offers a line of replacement compressors, available from 1.5 to 5 horsepower, which deliver new levels of performance. The compressor is optimized for R-22 and R-407C refrigerants, which are designed for post-2010 aftermarket service applications. Copeland Scroll has opened the door in the HVAC business by providing a compressor that is both environmentally friendly and innovative.

Due to the phase-out of hydrochlorofluorocarbons, Emerson focused on designing a product line for aftermarket replacement needs. The ZRK5 has been engineered with the latest in technology and innovation. ZRK5 is available with polyolester (POE) lubricants to increase compatibility with both R-22 and hydrofluorocarbon refrigerant applications like R-407C. The product line for the ZRK5 compressor has been consolidated from 51 to 12 models for easier compressor stocking.
