Single Screw Inverter driven Chiller using VVR technology for high efficiency and reduced footprint for application and replacement projects - R-134a refrigerant

A. Battisti - Area Sales Manager


  • Cooling capacity range between 449-2074 kW 
  • Full flexibility with 3 efficiency versions: Silver, Gold, Platinum  
  • ESEER and EER up to 9.08 and 5.93 respectively 
  • Inverter driven Single Screw Compressor with Variable Volume Ratio (VVR) technology   
  • Low noise option, sound configurations: Standard, Low and Reduced 
  • R-134a Refrigerant  
  • 40% foot print reduction and unit width of 865m, Convenient for you replacement project.   



  • Outstanding reliability with the option of one or two truly independent refrigerant circuits  
  • Stepless capacity control by means of inverter driving the compressor motor 
  • Variable Volume Ratio (VVR) technology allows the compressor to adapt the discharge pressure of the refrigerant to the specific operating conditions reducing energy losses inside compressor and increasing unit efficiency 
  • Quiet operation with low sound levels are achieved at part loads due to reduction of compressor rotational speed (Optional compressor sound proof cabinet is available to further reduce sound level). 
  • No current spikes at start-up, always lower than full load current (FLA). 
  • Master/ Slave (M/S) control with functionality that allows to manage up to 4 chillers installed in parallel on the same water loop 
  • Sound proof compressor enclosures for enhanced acoustic attenuation and improve aesthetics of the unit 
  • Displacement power factor always > 0.95 to ensure the reduction in electrical losses in cables and transformers 
  • Extensive safety devices such as: freeze protection, high pressure switch and transducer, oil pressure sensor, phase monitor, compressor discharge temperature, thermal over load relays and many more as standard 


  • High efficiency flooded shell and tube Evaporator and Condenser with Victaulic water connection as standard 
  • The MicroTech III controller with Superior control logic and compatibility with LonWorksBACnet, Ethernet TCP/IP or ModbusRTU communicationsand Daikin cloud monitoring platform Daikin on Site 
  • Total Heat Recovery option using an individual plate to plate heat exchanger for each refrigerant circuit  
  • 40% Reduced footprint, units below 900Kw with reduced  unit width below 900mm with electrical panel knock-down option allowing installation through a doorway 
  • Optional Marine version composed of modification to meet the specific need and transport
