Daikin Centrifugal Chiller DWDC is a water cooled two in one chiller solution designed for outstanding part-load efficiency and system redundancy.

  • Cooling capacity range: 2100-9000kW (R134a e R513A) / 1580-6700kW (R1234ze)


  • Two single stage centrifugal compressors
  • Optional Variable Frequency Drive (VFD) starter for high part load efficiency
  • Unloading to 5% of full load provides chilled water temperature stability and ensures compressors’ durability, thanks to less harmful cycling
  • High efficiency flooded type shell and tube evaporator/condensers 
  • Simplified maintenance procedures: the main components can be removed or repaired with no need to shut down the unit as the chiller has back up components (compressors, lubrication systems, control systems and starters)
  • Low equipment, installation and annual operating costs than two single compressor chillers 


  • Positive pressure system design eliminating air and moisture contamination providing sustainable performance and troublefree ownership 
  • Daikin precision engineered gear driven design allows for lighter components, less vibration and ability to select gear ratio to provide optimum impeller speed specific to your application 
  • A standalone lubrication system featuring an electric oil pump supplying the lubrication at controlled temperature and pressure to all bearing surfaces, and to act as the source of hydraulic pressure for capacity control system 
  • Quiet operation using the unique liquid injection by taking a small amount of liquid refrigerant injected into the compressor discharge area where the droplet absorbs sound energy and reduces the compressors overall sound level 
  • Quieter operation sound level as chiller unloads using Daikin compressor design 
  • 20% more performance achieved within the same footprint as comparative competitor products  


  • Marine water boxes providing tube access for inspection and cleaning without dismantling water piping 
  • ANSI raised face flanges on either the evaporator or condenser (Victaulic connections as standard) 
  • Water side high pressure water system up to 300 PSI 
  • Refrigerant leak detector  
  • Sound attenuation package
