  • Cooling capacity range: 7750 kW to 11400 kW
  • Counterflow centrifugal chillers with two stage compressor
  • Two efficiency packages - Standard and Premium (0.648kW/ton and 0.616 kW/ton respectively)
  • R-134a refrigerant


  • Chiller series counterflow arrangement provides the full load efficiency advantage of two separate chillers arranged for counter flow operation in a single compact unit. Also enabling each compressor to operate at lower head to increase the energy performance at full load
  • Daikin precision engineered gear driven design allows for lighter components, less vibration and ability to select gear ratio to provide optimum impeller speed based on building demand
  • *Evaporator water: 13.3/4.5°C – Condenser water: 35/40.5°C
  • Ensuring the lowest total cost of ownership in district cooling or large size cooling plants applications
  • The controls are pre-wired, adjusted and tested
  • Positive Pressure Design


  • 2 circuits arranged in series – counter flow (for each unit of the package)
  • Unique innovative 'back-to-back' impeller design resulting in reduction of 67% trust load and improved reliability and bearing life
  • Unique diffuser control to avoid surging resulting in 10% efficiency increase at part load versus hot gas bypass
  • Flooded & shell tubes evaporator and condenser, including two separate refrigerant circuits
  • BAS communication capability via LONMARK, Modbus or BACnet standard protocols for BAS manufacturers
  • Low noise and vibration with Daikin gear drive technology
  • Built-in redundancy with two of everything connected to the evaporator and condenser (2x drive lines, lubrication and control systems, expansion vales and economiser)
  • Packaged solution, bolt-together construction on single and dual compressor chillers
  • Optional factory disassembly to overcome site access restrictions

Certified in accordance with the AHRI Water-Cooled Water-Chilling Packages Certification Program, which is based on AHRI Standard 550/590 (I-P) and AHRI Standard 551/591 (SI). Certified units may be found in the AHRI Directory at www.ahridirectory.org
