EVERGREEN® 19XR,XRV High-Efficiency Hermetic Centrifugal Liquid Chiller 50/60 Hz HFC-134a
19XR — 200 to 1500 Nominal Tons (703 to 5275 kW) 19XRV — 200 to 1500 Nominal Tons (703 to 5275 kW)
evergrn Carrier’s Evergreen® centrifugal chillers offer: • The use of non-ozone depleting refrigerant HFC-134a, which is not affected by scheduled refrigerant phaseouts • An annual leak rate of 0.1%, the lowest published in the industry • The ability to store the entire charge of refrigerant inside the chiller, minimizing the chance of leaks during refrigerant transfer for maintenance • Hermetic compression • Refrigerant-cooled VFD (variable frequency drive) (19XRV only) • Modular construction • Positive pressure design
The Carrier-designed Evergreen family of chillers achieve superior efficiencies without compromising the environment.
The Evergreen chillers superior efficiencies are obtained at true operating conditions. Therefore, the effects of potential direct or indirect global warming are greatly diminished.
Today’s owners of chilled water plants demand high efficiency from their chillers. Per AHRI 550/590, chillers operate at design conditions less than one percent of the time. As a result, superior part load efficiency is required for today’s chilled water applications.

The Evergreen® 19XRV centrifugal chiller, equipped with a factoryinstalled variable speed drive, maximizes chiller efficiency by optimizing compressor operation. Electric power consumption drops dramatically when the motor speed slows. The 19XRV chiller delivers industry-leading integrated part load values (IPLV). together, making the Evergreen chillers ideally suited for replacement projects where ease of disassembly and reassembly at the jobsite are essential.
