Wide Application
The Carrier 19XR/19XRV 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.
