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.
