Johnson Controls previewed the high-density, compact YORK YK-HT two-stage economized centrifugal chiller at AHR Expo 2026. Engineered for data centers and large industrial, pharmaceutical and healthcare campuses, the YK‑HT delivers a wide operating range from a single driveline, operating with condenser leaving fluid temperatures up to 165°F and up to 110°F of lift. This supports efficient closed‑loop heat rejection with dry coolers and enables heat‑pump and heat‑recovery applications. By reusing thermal energy that would otherwise be wasted, these systems can offset more than 35 MMBtu per hour. 

 It can produce 44°F chilled water and 140°F hot water at the same time while delivering efficiency levels that exceed ASHRAE requirements. This unified feature eliminates the need for cascaded systems, extra electrical infrastructure or major mechanical room redesigns. With a footprint nearly 30% smaller than most alternatives, the unit is well suited to fit more easily into existing legacy chiller spaces. Other efficiency and performance features include: Low-GWP refrigerants R 1234ze and R 515B, an integrated lubrication system and dual variable geometry diffuser control, flash tank economizer for enhanced efficiency, optional variable speed drives for increased efficiency and BESS compatibility and factory-equipped with Smart Ready connectivity.
