Johnson Controls has introduced the NexusPremier™ 25-ton and 50-ton HVAC units, designed to provide superior standard efficiency while reducing operational costs.
Depending on local codes, NexusPremier can achieve a 50 percent higher-than-required efficiency, according to Rick Schnarr, the firm’s vice president of sales for commercial and applied ducted systems. The product line is equipped with a complete range of factory options for easier specification and is smart technology-compatible for reduced operating costs.
The NexusPremier includes standard efficiency models that comply with stringent Department of Energy 2023 energy efficiency standards. Additional options are available for each tonnage to meet the Consortium for Energy Efficiency (CEE) 2019 highest-tier ratings. The features yield significant cost savings over the unit’s operational life.
The units streamline the design process with integrated system selection tools, easily accessible building information modeling (BIM) files, improved submittals and simplified specifications. Additional flexibility is provided on high-performance base models through a complete range of factory options, including various airflow path configurations, indoor environmental quality options and modulating options for improved comfort.
NexusPremier rooftop units are Smart Equipment-enabled and offer start-up wizards and an array of user-adaptable parameters to help expedite start-up and commissioning. Smart Equipment provides complete control across multiple available rooftop units and seamlessly integrates with interfaces, including zone controllers and other building controls systems.
