centrifugal liquid chillers
Industrial
19XR/XRV
Options/accessories
• Two types of unit-mounted variable
frequency drives (VFDs): standard
and high tier, to match different
customer requirements in terms of
cost and electrical performances
• Refrigerant isolation valves allow
the refrigerant to be stored inside
the chiller during service
• Pumpdown unit, combined with
the refrigerant isolation valves,
eliminates complex connections to
portable transfer systems
• Unit-mounted starter reduces
machine installation time and
expense
• High-voltage motors available: 3000
V, 3300 V, 6300 V
• CCN/JBus: remote connection
• 21 bar water heat exchanger
• Nozzle with flanges (water inlet/
outlet with flanges)
• Delivered in four sections to
facilitate the installation
Features
• Nominal cooling capacities from 1000 to 5300 kW.
• Mix-match capabilities – a complete line of compressors and heat exchangers
to ensure the optimal combination of machine components regardless of
capacity, lift and efficiency specifications.
• Hermetic compressor – elimination of leak risks from the compressor/motor
shaft sealing in an open compressor.
• Single-stage compressor with special features – aerodynamically contoured
impellers, variable inlet guide vanes and movable diffusers for better product
reliability and compressor part and full-load operating efficiency.
• Variable speed compressor capability – improvement of part load efficiency
and electrical performance.
• Heat exchangers certified by the European pressure vessels code (PED).
• Carrier numerical product integrated control offers unmatched flexibility and
functionality. Each unit integrates directly with the Carrier Comfort Network
(CCN), providing a system solution to controls applications.
