AquaEdge® - Ceramic bearing centrifugal liquid chiller using HFO R-1233zd refrigerant 19DV

Reliable

• Advanced back-to-back two-stage compressor naturally balances both radial and axial thrust on shaft
• Simple and robust ceramic bearing system enables refrigerant lubrication that doesn’t request oil lubrication which is requested by conventional chillers
• High tier variable speed starter
• Swift restart – 19DV can restart 30 seconds (with UPS) after power recovery

Efficient

• High speed direct drive motor reduces mechanical loss by 75% resulting from the removal of gear driven system
• Pioneer falling film evaporator is designed for low pressure refrigerant, which performs a significantly enhanced heat transfer efficiency by mitigating submergence effect especially at part load conditions
• High performance tubing with internally and externally enhanced fins
• Greenspeed^® variable speed control

Sustainable

• PUREtec™ R-1233zd(E) is new non-Ozone Depletion Substances, the ultra low Global Warming Potential of ~ 1, non-flammability and non-toxicity refrigerant that provides a safe and environmentally steward solution to centrifugal chillers
• Carrier pioneer falling film evaporator design helps reduce the refrigerant charge significantly
• Lower electrical power consumption
• Significant reduction of related CO₂  emissions

Flexible

• System layout of 19DV chillers is well optimized and specific crescent shape economizer is designed to best leverage the space between evaporator and condenser that brings up to -15% smaller footprint versus legacy R-123 unit
• Patented re-locatable control panel could be installed at any of the four corners of the chiller, which makes the layout of chillers more flexible to fit the site conditions
• Bolt together modular design is ideal for retrofit project or installation in limited place
• Miscellaneous optional offerings help to facilitate daily maintenance on jobsite

Quiet

• Low noise Greenspeed^® variable-speed fans
• Refrigerant-cooled hermetic motor, no gear driven, optimized flow channel and 60% impeller speed of legacy design, all these features contribute to reduce refrigerant airflow noise
• Greenspeed^® variable speed control adaptively turns down impeller speed at part load for better acoustic performance

Smart

• PIC6 intelligent control – color touch screen, intuitive menu, animated component level interface, graphic trending, auto pushed alarm mail, smart password and more than 10 languages for choice
• Multiple remote access methods present the users a flexible way to monitor and control chillers
• Online data management and analysis, daily and key performance reports, prognostics and preventative maintenance
