YORK ® YK Chillers, manufactured by Johnson Controls, offer a complete combination of features for total owner satisfaction.

Matched components maximize efficiency

Actual chiller efficiency cannot be determined by analyzing the theoretical efficiency of any one chiller component. It requires a specific combination of heat exchanger, compressor, and motor performance to achieve the lowest system kW/ton. YORK ® chiller technology matches chiller system components to provide maximum chiller efficiency under actual – not just theoretical operating conditions.

Real-world energy performance

Johnson Controls pioneered the concept of “Real-World Energy” to illustrate the energy-saving potential of focusing on chiller performance during off-design conditions. Off-design is not only part load, but full load operation as well, with reduced entering condenser water temperatures (ECWTs). This is where chillers operate 99% of the time, and where operating costs add up.

YORK ® centrifugal chillers are the only chillers designed to operate on a continuous basis with cold ECWT and full condenser flow at all load points, taking full advantage of real-world conditions. This type of operation benefits the cooling tower as well by reducing the cycling of the fan motor and ensuring good coverage of the cooling tower fill.

YORK ® centrifugal chillers offer the most efficient real-world operation of any chiller, meaning lower operating costs and an excellent return on your chiller investment.

Open-drive design

Hermetic motor burnout can cause catastrophic damage to a chiller. The entire chiller must be cleaned and the refrigerant replaced. YORK ® YK centrifugal chillers eliminate this risk by using aircooled motors. Refrigerant never comes in contact with the motor, preventing contamination of the rest of the chiller.

Insurance companies that offer policies on large air conditioning equipment often consider aircooled motors a significant advantage over hermetic refrigerant-cooled units.

High efficiency heat exchangers

YORK ® YK chiller heat exchangers offer the latest technology in heat transfer surface design to give you maximum efficiency and compact design. Waterside and refrigerant side design enhancements minimize both energy consumption and tube fouling.

Single stage compressor design and efficiency proven in the most demanding applications

Designed to be the most reliable chillers we’ve ever made, YORK ® YK centrifugal chillers incorporate single-stage compressor design. With fewer moving parts and straightforward, efficient engineering, YORK ® single-stage compressors have proven durability records in hospitals, chemical plants, gas processing plants, the U.S. Navy, and in other applications where minimal downtime is a crucial concern.

In thousands of installations worldwide, YORK ® single-stage compressors are working to reduce energy costs. High strength aluminum-alloy compressor impellers feature backward curved vanes for high efficiency. Airfoil shaped pre-rotation vanes minimize flow disruption for the most efficient
