Centrifugal chillers

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:

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:

  • 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.

Absorption Chillers

The Carrier Corporation has more than 100 years’ experience in providing HVAC systems and equipment around the world and offers a complete product solution for many different types of application, from residential to industrial.

  • Nominal cooling capacities from 90 to 4652 kW.
  • The absorption chillers are designed for cooling applications where low-pressure steam is available as waste heat.
  • Designed to provide chilled water from waste heat sources, generated from industrial processes and cogeneration systems.
  • Allows diversification of critical cooling requirements. Critical cooling loads are met with minimal electrical power input.
  • Allows use of smaller emergency generators since the electrical load associated with an absorption chiller is minimal compared to an electrically driven chiller.
  • Ozone-friendly and CFC-free
  • If needed, cooling requirements are met without use of refrigerants.
  • Minimises global warming effect by greatly reducing power consumption and eliminating the generation of greenhouse gases.
  • Reduced noise and vibration levels. The absorption chiller does not use a large motor-compressor, leading to quiet, vibration-free operation.
  • Small footprint. The high efficiency associated with double-effect chillers results in a reduction of the required installation space.
  • Auto-diagnosis system monitors operating conditions, predicts chiller information and maintains stable operation.
