MILWAUKEE — The York® brand of Johnson Controls has relaunched two series of 3- to 12.5-ton commercial rooftop units that provide a wide offering of performance-focused comfort solutions for commercial environments. The York Direct Fit and York Predator have been relaunched as York Sun Core and YORK Sun Pro, respectively.

With this relaunch, both platforms now feature a new three-stage cooling option. Upgrading the airflow strategy from constant volume to three-stage cooling with IntelliSpeed™ control can offer up to a 3.4 IEER (26%) increase on comparable models. The ultra-high-efficiency Pro rooftop units offer up to 21 IEER. Both platforms have models to meet U.S. Department of Energy (DOE) 2023, ASHRAE 2016, and IECC 2015 requirements.

Core units are economically designed for new construction and direct replacement applications to minimize the need for transition curbs, while the Pro units offer a premium cabinet with maintenance-friendly standard features for service professionals.

“Our mission to advance the efficiency, comfort, and intelligence of buildings inspired us to redefine the Pro and Core rooftop units,” said Eric Newberg, director, commercial product management, ducted systems, North America, Building Technologies & Solutions, Johnson Controls. “Further, in an effort to provide greater clarity to our customers, we’ve renamed these rooftop units to better align with our other recent product launches and provide a more intuitive view of the value of each platform. We now offer the Core, Pro, Choice, Select, and Premier rooftop platforms that increase in feature set and tonnage, along with other legacy platforms.”

Core and Pro rooftop units are Smart Equipment-enabled. This sophisticated, prepackaged controls platform helps maximize control for greater efficiency, extended equipment life, and reduced operating costs. Smart Equipment also provides seamless integration with leading building controls systems, including Verasys. An optional mobile access portal (MAP) gateway with a Wi-Fi® hotspot provides access to commissioning, configuration, and maintenance logs using a mobile smart device for fewer trips to the job site or the roof to diagnose issues.

Both platforms have multiple airflow strategies, including constant volume (CV), IntelliSpeed™ single zone variable air volume (SZVAV), continuous reset single zone (CRSZ), and variable air volume (VAV). Additionally, Core and Pro rooftop units offer many options and accessories to perfectly match a building’s needs and make specification as simple as possible.
