Features

Reliable

Advanced back-to-back two-stage compressor naturally balances both radial and axial thrust on shaft.
Simple and robust refrigerant lubricated ceramic bearing system without the limitations of conventional oil lubricated chillers. Customers won’t be troubled by oil related failures as well as maintenance cost.
High tier variable speed starter equipped with harmonic filter(optional), total harmonic distortion (THD) ≤5% and fully complies with IEEE519 standard.
Swift restart – 19DV can restart within 30 seconds (with UPS) after power recovery (There would be around 5-seconds tolerance due to different site conditions.) and quickly regain capacity, providing added reliability for mission critical facilities such as data center applications.

Efficient

  • 19DV chillers can achieve up to 7.3 full load COPR and 12.3 IPLV.IP at AHRI conditions.
  • Carrier back-to-back two-stage compressor integrated with inter-stage economizer which improves both cooling capacity and efficiency.
  • High speed direct drive motor reduces mechanical loss by 75% resulting from the removal of gear driven system.
  • With the application of refrigerant lubricated bearings, potential efficiency drop through oil logging of the heat exchangers is eliminated in 19DV.
  • Pioneer falling film evaporator is designed for low pressure refrigerant, which brings significantly enhanced heat transfer efficiency by mitigating submergence effect especially at part load conditions.
  • High performance tubing with internally and externally enhanced fins improves chiller efficiency by reducing overall heat transfer resistance.
  • GreenspeedTM variable speed control gives a instantaneous control of compressor speed to adapt building load changes perfectly, which ensures that the chiller is always operating efficiently at both full load and part load.
