Daikin Comfort Technologies North America has introduced the Nexio Max, an inverter-driven rooftop heat pump built for light commercial applications, the Waller, Texas-based manufacturer announced July 8. Nexio Max is designed to support building electrification projects while giving contractors and consulting engineers a retrofit-friendly option that uses lower-global-warming-potential R-32 refrigerant paired with variable-speed compressor technology.
The unit is available in 7.5-, 8.5- and 10-ton capacities, delivering up to 114,000 Btuh of cooling. Daikin said the platform was built to serve light commercial building owners navigating the shift toward electrified heating and cooling systems, while giving contractors a straightforward option for both retrofit and new-construction jobs.
Nexio Max Built for Retrofit Compatibility
Daikin said Nexio Max was designed to simplify replacement projects by aligning with common rooftop unit footprints, avoiding the need for a curb adapter in most swap-out installations. That footprint compatibility is intended to preserve existing curb and ductwork connections on jobs where a building owner is replacing an aging rooftop unit rather than starting from a bare roof, a scenario contractors frequently encounter on light commercial retrofit work. Factory-wired and labeled connections are meant to streamline startup and commissioning, while the cabinet is designed to give technicians direct access to key components for service and maintenance.
"Nexio Max was developed to address the evolving needs of light commercial building owners, contractors, and consulting engineers," said Sachin Dixit, vice president of commercial product marketing at Daikin Comfort Technologies, in the company's announcement. "By combining inverter-driven technology, low-GWP R-32 refrigerant, and advanced controls, the platform is designed to deliver efficient operation, installation flexibility, and occupant comfort."
Nexio Max Rated for Cold-Climate Heating Performance
Daikin said the Nexio Max delivers up to 22 IEER cooling efficiency and maintains heating performance in cold conditions, operating at outdoor ambient temperatures as low as minus 13 degrees Fahrenheit while still providing 85% of rated heating capacity at 14 degrees. Mitul Lakdawala, director of light commercial product marketing at Daikin, said the unit includes standard single-zone variable air volume functionality along with native BACnet integration, plus configurable options such as multi-zone VAV and hot gas reheat for buildings with more specialized comfort or humidity-control needs.
The Nexio Max's BACnet integration is intended to let the unit connect directly with a building's management system for real-time monitoring and control, and the units are compatible with a range of third-party thermostats in addition to Daikin's own controls. Daikin said remote monitoring, diagnostics and control are also available through its Hero platform, giving contractors and facility managers a way to track unit performance without an on-site visit.
Inverter-Driven Compressors Target Low-Noise Operation
Daikin said the Nexio Max's inverter-driven compressors are designed to manage cycling behavior and hold consistent sound levels, an increasingly common request on light commercial jobs sited near occupied space or in mixed-use developments. The unit also uses direct-drive fan technology rather than belt-driven fans, a design Daikin said reduces certain maintenance items while supporting low-sound operation. Integrated power protection with phase-monitoring capability is built in to help protect critical components and reduce unplanned downtime.
The Nexio Max enters a light commercial rooftop segment where Daikin competes against other major manufacturers offering electrification-focused heat pump platforms, as building owners increasingly weigh options for replacing aging gas-based rooftop equipment with electric heat pump systems that can handle both heating and cooling loads. Daikin has continued to expand its R-32 product lineup across residential and light commercial categories as the refrigerant transition away from higher-GWP options continues across the industry.
Daikin Comfort Technologies North America markets its residential and light commercial product lines, including Nexio Max, through a network of distributors and dealers across the United States. The company did not disclose pricing for the new platform or provide a specific timeline for expanding Nexio Max into additional tonnage ranges beyond the initial 7.5-to-10-ton lineup.
The Nexio Max launch adds to a broader wave of light commercial heat pump introductions this year as manufacturers respond to demand from building owners seeking to electrify heating systems ahead of anticipated code changes and utility incentive deadlines in several states. Daikin said additional details on Nexio Max availability and distributor training would be provided through its dealer network in the coming weeks.
Light commercial rooftop equipment in the 7.5-to-10-ton range is commonly specified for small retail buildings, restaurants, medical offices and other single-story commercial spaces where a handful of packaged units typically cover the entire building's heating and cooling load. Contractors serving that segment have increasingly fielded requests from building owners for electric alternatives to gas-fired rooftop units, particularly in markets where utilities or local code officials have signaled tighter restrictions on new fossil-fuel equipment in commercial construction. Daikin said the Nexio Max platform is intended to give those customers a heat pump option that does not require contractors to depart from familiar rooftop unit installation practices.
Daikin Comfort Technologies North America is a subsidiary of Daikin Industries and operates separately from Daikin Applied, the company's applied commercial systems business that focuses on larger chillers and air handling equipment. Nexio Max falls within Daikin Comfort Technologies' light commercial product family, which is sold primarily through independent distributors and dealer networks rather than the direct sales channels Daikin Applied uses for its larger applied systems business.
