YORK® YK Centrifugal Chiller
250-3,000 TR (880-10,550 kW)
Although less than 5% of the global-warming potential (GWP) of a centrifugal chiller comes from the refrigerant it uses, we still take this contribution seriously. But simply adding a lower-GWP refrigerant to an existing chiller won’t solve the problem. The chiller will either run less efficiently or at a lower cooling capacity, or both. To solve this, the re-engineered YORK® YK chiller has been designed specifically for use with R-1234ze as the primary* refrigerant.
Additional Benefits
- Re-engineered YK chillers can be shipped from the factory with ultra-low GWP refrigerant R-1234ze or low-GWP refrigerants R-513A or R-515B, all without a size penalty.
- YK chillers are designed and tested to ensure refrigerant stays inside the chiller for reduced refrigerant emissions.
- The state-of-the-art OptiView™ Control Panel optimizes chiller performance by precisely controlling the leaving chilled liquid temperature and motor current.
- Variable-speed drive (VSD) technology can operate up to 30% more efficiently in the real world versus chillers optimized for a single, full-load efficiency.
*Also available with R-513A and R-515B refrigerants

YORK® YK-CP Economized Cycle
Centrifugal Chiller
2,000-3,000 TR (7,033-10,550 kW)
The YORK® YK-CP Economized Cycle Centrifugal Chiller includes all of the benefits of the YORK® YK Centrifugal Chiller while adding an efficiency-enhancing economizer and a modular configuration that allows customization for each application. From unmatched efficiency and greater application support to optimization for ultra-low GWP refrigerants and a more compact footprint, the YK-CP is the future of sustainable cooling technology.
Additional Benefits
- Newly designed economizer captures refrigerant gas during the expansion process and reinjects it back into the compressor to improve the overall efficiency of the refrigeration cycle and reduce the amount of refrigerant required.
- Modular design is more easily assembled and can be customized for specific applications, providing added flexibility and adaptability with consistent layout design across the different chillers.
- An optimized, forged converging suction line provides a streamlined refrigerant flow that minimizes losses and reduces the overall footprint of the chiller.

YORK® YK-EP Centrifugal Chiller
2,500-3,500 TR (8,800-12,300 kW)

Features
- Designed with sustainability in mind, the re-engineered YK chiller has been optimized specially for use with ultra-low GWP refrigerant R-1234ze
- State-of-the-art OptiView™ Control Panel optimizes chiller performance by precisely controlling the leaving chilled liquid temperature and motor current
- Quick Start feature restarts the chiller in as few as 45 seconds and reaches the specified chilled-water temperature faster than other centrifugal chillers
- Optional OptiSound™ Control works alongside standard VSD technology to minimize gas-flow disruptions that cause noise
- ISASecure® certified YORK® Chiller Access Manager provides secure access to chiller controls to help mitigate the risk of unauthorized access and security breaches
- Extraordinary flexibility allows the YK chiller to be ordered with a variety of options, including heat exchangers, gears and open-drive motors minimizing the need to order a larger size chiller package than might actually be necessary
- Compared to chillers that can only use a minimum 75°F (24°C) ECWT, a YK chiller can operate with ECWT as low as 55°F (13°C), reducing instantaneous energy consumption by as much as 50%
- Open-drive design and infinite life bearings help ensure maintenance needs on the YK chiller are minimized
