As commercial HVAC applications rapidly evolve, NEXIO Max Inverter Rooftop Units deliver high efficiency, flexibility, serviceability and control to meet today’s building demands. Whether it’s schools, retail spaces or offices, building owners are demanding solutions that offer efficiency, comfort, low operating costs, quiet operation, and integration with modern platforms. 

In commercial environments, these demands can be even more dynamic. Occupancy can fluctuate significantly throughout the day, from quiet mornings to peak operating hours and seasonal surges. Maintaining consistent comfort across open floors, offices, classrooms, and entryways is critical not only for occupant experience but also for encouraging long, comfortable visits. 

Commercial owners and operators are increasingly seeking HVAC systems that operate quietly, minimize humidity swings, and integrate seamlessly with building management systems without disrupting daily operations. 

NEXIO Max rooftop units are designed with variable speed inverter compressor technology, low-GWP R-32 refrigerant, and advanced system controls. By modulating capacity to match actual building load conditions, NEXIO Max delivers higher part-load efficiency compared to fixed-speed systems, occupant comfort, humidity management, and performance throughout the year.  

Built on Daikin’s inverter expertise and optimized for both replacement and new construction projects, NEXIO Max offers the flexibility and serviceability that contractors, engineers, and retail operators expect from a next generation rooftop solution. 

1. Inverter Technology for Real-World Commercial Operation 

NEXIO Max continuously adjusts compressor and fan speeds to match building demand, unlike traditional fixed-speed rooftops. This provides temperature stability, humidity control, and energy efficiency during part-load operation -compared to traditional fixed speed rooftops - providing comfort across a wide range of applications including schools, offices, retail stores, restaurants, and healthcare facilities. 

2. Flexible Controls and BAS Integration 

NEXIO Max is designed for today’s connected buildings with factory-integrated controls that help simplify commissioning and building automation system (BAS) integration. Factory-installed BACnet® 

MS/TP streamlines BAS connectivity, eliminating the need for complex field-installed control packages. The platform also enables rooftop functionality, including multi-zone VAV operation delivering heating and cooling across building areas, modulating indoor fan control for energy efficiency by matching airflow to real-time demand, and remote diagnostics and monitoring using the HERO Cloud platform. 

This flexibility empowers contractors, controls integrators, and facility managers to optimize comfort, airflow, and energy performance across a variety of commercial applications.
