SPECS OVERVIEW

  • 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, 3 sound configurations: Standard, Low and Reduced
  • R-134a Refrigerant
  • 40% foot print reduction and unit width of 865m, Convenient for you replacement project.

BENEFITS

  • 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.

FEATURES

  • 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 LonWorks, BACnet, Ethernet TCP/IP or ModbusRTU communications, and 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
