Copeland Stream Semi-Hemertic Compressor

A brand new range of semi-hermetic four and six cylinder compressors. The series provides best in class performance for today’s HFC, natural and low GWP refrigerants, significantly reducing cost of operation and environmental impact compared to competing products.

The Stream Series Features

  • Range of 8 models from 62 to 153 m3/h for today’s HFC refrigerants
  • One model suits all applications as it is compatible with R404A, R407F, R448A, R449A, R22, R134a, R407A, and R407C
  • Improved product range versus Discus: three additional models and two specific models with extended cooling capacity providing the best selection flexibility
  • Range of 3 models for CO2-transcritical applications from 20 to 38 kW

Technical Highlights

  • Best-in class seasonal efficiencies, up to 15% higher than semi-hermetic reciprocating compressors known in the market
  • Reduced sound level for quiet operation up to 7dBA
  • Reduced dimensions and weight by up to 45 kg
  • Wide operating envelope, one model fits all refrigeration applications, medium and low temperature
  • Availability of 2 motor versions per displacement
  • No cooling fan required for low temperature (0°C Suction Gas Return Temperature) to keep applied cost low
  • Extremely low condensing temperatures for increased system efficiency
  • Emerson CoreSense Diagnostics technology providing advanced protection & diagnostics to ensure long compressor lifetime
  • Protection and sensing devices pre-installed to reduce applied system cost
  • Current sensor allowing for individual compressor power monitoring to stay on top of energy costs
  • Integrated status LEDs for local communication via colour and flash codes
  • Remote communication via Modbus for faster service
  • For CoreSense Diagnostics see separate data sheet for full details

All Stream compressors are released for two different options of capacity modulation:

  • Variable speed release from 30 to 70 Hz for capacity modulation related energy savings
  • Continuous modulation from 50-100% (4-cylinder) and 33-100% (6-cylinder) ensuring a perfect match of capacity to refrigeration load

Stream Technology And Its 5 Key Benefits

  1. Diagnostics
    CoreSense™ Diagnostics technology helps your refrigeration equipment last longer. This technology offers advanced compressor protection, diagnostics, communication and power consumption measurement.
  2. Efficiency
    Its unique valve technology makes Stream 10% more efficient than any other compressor and therefore helps you reduce the carbon footprint and running cost of your installation.
  3. Multi Refrigerant
    Its unique valve technology makes Stream a multi refrigerant compressor. One model suits all applications without any compromise on performance.
  4. Modulation
    Digital technology or operation with inverter makes Stream the most flexible choice for continuous capacity modulation.
  5. Low Sound
    Sound shell technology makes Stream the quietest compressor on the market for sound critical applications.
