YORK® models YK and YD Centrifugal Chillers

• Environmental Responsibility - HFC-134a refrigerant has zero ozone-depletion potential and low total global-warming potential. 
• Real-World Efficiency - Designed for maximum efficiency in the real world, where 99% of the cooling season is spent at off-design conditions.
• Unsurpassed Energy Savings - With the OptiSpeed™ Drive, energy consumption can be as low as .20 kW/TR, reducing annual energy costs by as much as 30%. 
• Earn LEED® Points - Earn points for Energy and Atmosphere (EAc1) and for Enhanced Refrigerant Management (EAc4). 
• Improve Sustainability - Falling-film evaporator reduces refrigerant charge up to 40%. Heat-recovery option in units up to 2,800 TR can provide 1,200 to 40,000 MBH of heat.
• Easy Operation - The OptiView™ Control Center ensures optimum performance and easy operation.
• Protects Temperature-Sensitive Applications - In the event of a power failure, chillers equipped with Quick Start feature can restart in as little as 25 seconds after emergency power is established.
