YK-HT Two stage centrifugal chiller

Up to 110° F Lift

The York YK-HT is engineered for data centers and large industrial, pharmaceutical and healthcare campuses. With condenser leaving fluid temperatures up to 165 °F and a 110 °F lift, the YK-HT delivers the industry’s widest operating range from a single driveline

Engineered for mission-critical, high-lift applications
Up to 110°F lift and 165°F leaving condenser water temperature expands the operating envelope beyond conventional single-stage chillers.
Expanded operating range enables greater cooling system design flexiblity to reduce dry cooler requirements, reduce cost, optimize plant space, and reduce sound.

YK-HT Two stage centrifugal chiller

Real world performance

These capabilities translate to significant real‑world impact on water and noise. When paired with dry coolers, the YK‑HT eliminates that water use entirely. For large data centers, including AI factories facing water conservation constraints and strict noise limits, the YK‑HT’s enhanced lift capability enables up to a 60% reduction in dry coolers and enough fan power reduction to lower onsite noise by as much as 20 dBA.

Benefits

Innovative & efficient

High lift up to 110 °F from a single driveline and leaving condenser temperatures up to 165 °F.

Space saving

The two-stage economized centrifugal chiller reduces footprint by nearly 30%.

Versatile

The YK‑HT delivers expanded functionality in a single packaged unit. As a unified heating and cooling platform for large buildings, it can produce 44°F chilled water and 140°F hot water at the same time. This unified feature eliminates the need for cascaded systems, extra electrical infrastructure or major mechanical room redesigns.

Features

Delivers the industry's widest operating range from a single driveline.
Nearly 30% smaller chiller footprint helps reduce mechanical room requirements and maximize available floor space.
Single-driveline architecture simplifies the system and reduces mechanical complexity compared to multi- compressor alternatives.
Optional variable speed drives for increased efficiency and BESS compatibility

Expanded operating range can reduce the number of required dry coolers by up to 60%, lowering heat rejection infrastructure costs and reducing system footprint.
Leverages trusted technologies including a falling-film evaporator, flash tank economizer and robust oil management system.
An integrated lubrication system and dual variable geometry diffuser control
