The YORK brand of Johnson Controls has launched a series of new rooftop units designed for easier installation and simplified service. The new SunPremier 25-50 ton rooftop units deliver superior standard efficiency levels while reducing operational costs over the life of the unit.

“We’ve engineered this platform with our customers in mind,” said Rick Schnarr, vice president of sales, Commercial and Applied Ducted Systems, Johnson Controls. “Industry-leading efficiencies are paired with dynamic feature options to decrease installation, maintenance and operating costs. It is all a part of our goal to provide performance confidence and value to our customers.”

SunPremier was engineered for ease of serviceability, with features including extended grease lines, accessible connections, service ports and lights, coil-cleaning hatches and much more. For each available tonnage, the platform complies with stringent Department of Energy (DOE) 2023 energy efficiency standards. Additional options are available for each tonnage to meet the Consortium for Energy Efficiency (CEE) 2019 highest tier ratings. This translates into significant cost-savings over the life of the rooftop unit.

The Smart Equipment-enabled units feature start-up wizards and an array of user-adaptable parameters to help expedite start-up and commissioning. The system offers complete control across all available rooftop units and integrates with other control systems and interfaces, including zone controllers and building management systems such as Verasys.

SunPremier rooftop units streamline the design process with integrated system selection tools, easily accessible building information modeling (BIM) files, improved submittals and simplified specification. Additional flexibility is provided on high-performance base models through the most complete range of factory options, including various airflow path configurations, indoor environmental quality options and modulating options for improved comfort.

Other features include:

  • Navigator product service app enabling on-demand access to unit-specific details, technical literature and a direct connection to technical support via a unique QR code on each rooftop unit (available spring 2019)
  • Optional Mobile Access Portal (MAP) provides remote monitoring capability for fewer trips to the job site or rooftop to diagnose issues
  • Design, engineering and assembly in the state-of-the-art Johnson Controls Rooftop Center for Excellence in Norman, Oklahoma
