19XR/XRV Single-Stage Centrifugal Liquid Chiller

19XR/XRV Single-Stage Centrifugal Liquid Chiller

Nominal cooling capacity from 1000 to 5300 kW

  • The centrifugal chillers provide exceptional value by achieving energy efficiency levels as high as 6.8 (EER) utilising proven technology designed specifically for chlorine-free refrigerants.
  • Unique concept of the hermetic compressor:
    – Single-stage aerodynamic impeller
    – Tunnel diffusers, based on aircraft engine technology
    – Motor cooled by refrigerant gas injection
  • Possibility to control the compressors using a variable frequency drive (19XRV) to maximise machine energy efficiency.
  • Use of high-efficiency evaporator and condenser tubes.
  • Expansion sub-cooler integrated into the condenser.
  • Patented float valve technology for optimised sub-cooling and refrigerant level in the evaporator.
  • These advantages, together with the modularity of the units and their efficiency, economical operation and dimensional constraints allow the use of the Carrier 19XR/19XRV centrifugal chillers in any high-capacity water cooling applications.
