SINGLE-STAGE CENTRIFUGAL LIQUID CHILLERS
Nominal cooling capacity 1000-5300 kW
Single-stage compressor Industry-leading Efﬁciency with VFD Standard or high-tier VFD on choice Wide Application Stable Operation Low Sound Level Modular Construction
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.
