Water Cooled Screw Chiller

Quiet Performance and Wide Operating Range

Where noise is a concern, the Daikin water-cooled screw chillers provide the ideal solution for sound sensitive environments. Designed with a single main rotor compressor which is inherently quieter than twin screw compressor designs, these chillers provide some of the lowest sound levels in the industry. Their quiet performance can eliminate the need for expensive sound attenuation equipment. And their low first cost means facility owners save money right from the start.

  • Wide operating map for applications ranging from comfort cooling to ice making
  • Two refrigerant circuits improve part load efficiency
  • Single main rotor compressor means inherently quieter operation than dual rotor compressors
  • Compact size fits through a 3-foot door for lower installed costs
  • Solid state starters are standard to provide controlled acceleration and deceleration with less compressor stress and vibration
  • Controls flexibility—MicroTech® II controls with our Open Choices™ feature for easy integration with the building automation system of your choice
  • R-134a refrigerant has no ozone depletion potential and no phase-out schedule
Ultra Quiet Operation
