Suppliers' New Product Preview Advertising Section Carrier delivers performance with EquiDrive TM Carrier's EquiDrive back-to-back compression and drive train technology provides more operating range while maintaining best-in-segment efficiency at design conditions. Designed to deliver high performance and reliability across a wide operating range, the all-new AquaEdge® 19MV water-cooled centrifugal chiller provides an improvement in both chiller energy efficiency and building resiliency. E nergy is reduced due to better efficiency at common metrics such as full load, 75% load (the " lifecycle point " ) and Integrated Part Load Value (IPLV). Due to a wider operating range, including the ability to operate at virtually no lift, the Carrier AquaEdge 19MV can take full advantage of cold condenser water, chilled water reset and other energy-saving practices to further improve building performance. In addition, building resiliency is significantly improved with its ability to operate with elevated condenser water temperatures at low and full load. This extended operating range (meaning it may go beyond the typical operating range) is a game-changing capability that provides building owners and facility managers confidence in reliable, efficient operation beyond specifications. back-to-back oil-free compressor technology. A more balanced design means reduced thrust loads. Optimized dual inlet guide vanes for better efficiency and stability. * Achieves <0.52 kW/Ton and <0.31 kW/Ton (IPLV) at AHRI conditions * Operating range of 40°F to 95°F (4.4°C to 35°C) entering condenser water down to 10% load * Expansion control system with dual Electronic Expansion Valves (EXVs) for optimized integrated waterside economizer (WSE) operation * Oil-free magnetic bearing system * Permanent magnet motor improves efficiency at full and part loads * Direct drive simplifies the design * Streamlined gas flow reduces internal losses Other features and options that make this chiller a perfect fit for any building and almost any cooling need include: Compact footprint for easy installation. Select models fit through double doors (72 " x 80 " ) with no disassembly required. (Bolt-together construction allows for easy disassembly and reassembly if required.) Quiet operation. Operates at less than 80 dBA. Economizer. Compact brazed plate economizer leverages the two-stage compressor design to increase refrigerant liquid subcooling and evaporator capacity, ensuring more performance per square foot. Refrigerant options. Available with choice of low GWP R-513A or R-134a refrigerant. Condenser and evaporator. High-performance tubing, low waterside pressure drop and integral subcooling provide high efficiency. Greenspeed® intelligence variable frequency drive. An air-cooled VFD enables starting and operating with cold condenser water while variable speed operation provides enhanced performance at off-design conditions. Its enclosure protects power electronics from airborne contaminants. Visit carrier.com/19MV or ask your local Carrier expert for details.
