Carrier's Evergreen
®
23XRV chiller is
the world's first integrated variable
speed, water-cooled, screw chiller.
It incorporates significant break-
throughs in water-cooled chiller tech-
nology to provide excellent reliability
and achieve superior efficiencies at
true operating conditions without com-
promising the environment.
The 23XRV chiller provides:
• Variable speed, positive
displacement screw compressor.
• Air Conditioning, Heating, and
Refrigerant Institute (AHRI) certified
efficiencies to 0.33 kW/ton (AHRI
IPLV).
• Chlorine-free HFC-134a refrigerant.
• IEEE-519 compliance for harmonic
distortion.
• An ideal solution for constant and
variable flow pumping systems.
Features/Benefits
Quality design and con-
struction make the Evergreen
23XRV chillers the best
choice for modern, efficient
chilled water plants.
Product reliability
The 23XRV chiller uses proven tech-
nology from Carrier's existing line of
Evergreen chillers along with innova-
tions that increase reliability. The
23XRV compressors are designed for
extremely high reliability. The ad-
vanced tri-rotor compressor features a
balanced rotor geometry and shorter
screw lengths, resulting in vastly re-
duced compressor bearing loads and a
minimum L10 compressor bearing life
in excess of 500,000 hours when op-
erated at AHRI conditions.
