YK Centrifugal Chillers

Real-World Performance

Every facility faces unique challenges. Whether an institutional building, manufacturing facility or a district energy central plant, and whether the ambient conditions are hot or cold, humid or dry, a facility must handle continually shifting challenges of climate and internal load variations. That's why YORK® created a centrifugal chiller designed to handle every project's unique situation. Built on the globally proven YORK® YK chiller platform, the re-engineered YK chiller is designed to deliver superior real-world performance in a variety of applications thanks to an exclusive combination of features.

Featured Products

Today's cooling solutions must be reliable and cost-effective while also being easy to manage, well supported, efficient year-round, regulations-compliant and capable of delivering on decarbonization goals. And that's exactly why the re-engineered YORK® YK Centrifugal Chiller was created.

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.

Benefits

ULTRA LOW GWP OPTIMIZED

The re-engineered YORK® YK chiller has been designed specifically for use with R-1234ze as the primary* refrigerant, without any increase in footprint.

LOWEST TOTAL COST  OF OWNERSHIP

Designed to be cost-effective across your entire bottom line, the re-engineered YORK® YK chiller delivers lower installation, operating and maintenance costs over the life of the chiller.

GREATER APPLICATION SUPPORT

The YK platform is versatile by design, enabling customers to leverage a wide array of components that help balance project needs with cost savings.

INTUITIVE CONTROL

Featuring a state-of-the-art, OptiView Control Panel, it's easier than ever to manage chiller operations with improved efficiency, reduced maintenance and greater security.

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
