HIGH-EFFICIENCY CHILLERS WITH SCREW COMPRESSORS  23XR/XRV Features and advantages COOLING ■■ The 23XRV Evergreen range offers superior solutions with record capacities from 970 to 1880 kW, EERs up to 6.5 and ESEERs up to 10.0. ■■ Innovative triple-rotor screw compressor design that features a balanced rotor geometry and shorter screw lengths. ■■ Variable-frequency drive compressor to maximise machine energy efficiency. Achieves ultra-high efficiency levels whilst lowering the cost of ownership. ■■ Combination of the reliability of a screw compressor with the energy savings of a variable-frequency drive (VFD). ■■ Unparalleled operational envelope that permits the chiller to operate under real-world adverse conditions. ■■ Ideal for both new construction and replacement using environmentally sound refrigerant (R-134a) at superior efficiency and with powerful controls. ■■ Mix-match capability with wide range of heat exchangers for unit performance optimisation. Condenser tubes Evaporator tubes Micro-grooved heat exchanger tubes to ensure optimised heat exchange between the refrigerant and the heat exchange medium.
