19 XR Hermetic Centrifugal Liquid Chiller

Cooling Capacity 1055-5274kW

Energy-saving and High Efficency

• Compressor key components design uses advanced jet engine technology.
• Aerodynamically contoured impellers - Impellers that use high back sweep main blades with low-rent and are smaller and lighter than profile intermediate splitter blades are aerodynamically contoured to improve compressor full-load and part-load operating efficiency.
• High performance tubing - Tubing with internally and externally enhanced fins improves chiller performance by reducing overall resistance to heat transfer. The new heat exchanger reduces refrigerant charge and manufacturing cost.
• Carrier patent AccuMeterTM system regulates refrigerant flow according to load conditions, provides a liquid seal at all operating conditions and eliminates unintentional hot gas bypass. Optimized piping design reduces refrigerant pressure loss and ensures chiller efficiency.

Stable Operation

• Variable inlet guide vanes - The guide vanes are connected with air-water piping, reducing installation craft-quality cable and controlled by a precise electronic actuator. The vanes regulate inlet flow to provide high efficiency through a wide operating range.
• Single-stage design - This increases product reliability by eliminating the additional moving parts associated with multiple stage chillers.

Environment Protection

Designed specifically for chlorine-free HFC-134a refrigerant (the environmentally preferred HFC-134a refrigerant with zero- ozone-depletion potential)

Advanced Designed

• The positive pressure design reduces the chiller size by up to 35% compared to low-pressure design. The smaller size minimizes the need for valuable mechanical room floor space. In addition, positive-pressure design eliminates the need for additional cost of low-pressure containment devices.
• Refrigerant-cooled oil cooler-Refrigerant cooling eliminates field water piping, reduces installation cost.
• Cooler and condenser are designed and manufactured in accordance with the Standard of Pressure Vessel of China. The unit isolation valves make the heat exchangers into a liquid containers and the pump out system is also provided to output refrigerant, which provides ease of maintenance.
• Mix-match capability - The chillers provide a complete line of compressors, motors and heat exchangers, ensuring the best combination of chiller components regardless of tonnage, lift, and efficiency specifications.
