Introduction
The AquaEdge® 19DV Water-Cooled Centrifugal Chiller is presented as a cutting-edge solution in heating and cooling technology, designed to adapt to varying building needs and climates. It offers innovative features and a full-system approach for efficient cooling and heating.

Specifications
The chiller operates with a capacity range of 350 – 800 Tons (1,231 – 2,814 kW) and uses the R-1233zd(E) refrigerant, known for its ultra-low global warming potential and ASHRAE A1 safety rating. It features a two-stage back-to-back compressor with ceramic bearings, a semi-hermetic motor, and a falling film evaporator.

Efficiency and Performance
The 19DV chiller emphasizes ultimate efficiency with its lift optimization technology, enabling effective heat recovery and free cooling. It can operate under demanding conditions, maintaining performance even outside standard conditions. The chiller is designed for both comfort cooling and heat recovery, offering significant energy savings and reduced maintenance costs.

Flexibility
The chiller can handle variable conditions, such as cold condenser water for free cooling and high-temperature water for heat recovery. It employs a variable orifice for efficient refrigerant metering and operates efficiently across a wide range of loads and temperatures.

Control and Intelligence
Equipped with Carrier’s SmartView™ control panel, the chiller offers intelligent control and monitoring. The SMART Service platform provides IoT-based analytics for predictive maintenance and energy consumption monitoring.

Sustainability
The 19DV is environmentally responsible, exceeding ASHRAE 2019 efficiency guidelines by over 40%. It operates with low sound levels and supports series counterflow configurations.

Reliability
The chiller's EquiDrive™ compressor technology ensures long-lasting bearing life, eliminating the need for complex oil management systems.

Benefits
Key benefits include robust VFD design, environmentally sustainable refrigerant, flexible SmartView™ interface, and intelligent analytics. System capabilities include variable flow, heat recovery, free cooling, and compatibility with various plant configurations.

Certification and Manufacturing
The chiller is certified under the AHRI Water-Cooled Water-Chilling and Heat Pump Water-Heating Packages Certification Program. Carrier's manufacturing facilities are LEED® certified, emphasizing energy efficiency and sustainability.
