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.
