Meet the Winners


Winner: Ephoca–Nextac

The next generation of PTAC

Innovation: Nextac’s next-generation PTAC includes features such as R-32 use, twin rotary inverter compressor, heat pump performance to -10°F (-23°C), integrated ERV, MERV 13, zero air leakage, self-cleaning coils, 27 dB(A) operations, STC of 40, sleek, all-metal paintable cabinet. No drain is required for cooling or heating. Nextac’s new high-efficiency and quality PTAC compels manufacturers to enhance their PTAC lineup by making them more efficient, aesthetically pleasing and adding more insulation for quieter operation and a better seal.

Finalists in this category include: Caleffi Hydronic Solutions, Caleffi XF; Intellihot Inc., Electron iE1.


Winner: Danfoss

DSG Compressor

Innovation: The DSG compressor has been specifically designed for low pressure refrigerants such as R-1234ze with low global warming potential. Applications include chiller systems, with a wide range of compressor capacities available to support unit design requirements. The DSG has been specifically designed for low pressure, low global warming potential refrigerants such as R-1234ze. These refrigerants would usually require a much larger compressor size to have the same capacity as high pressure (R-410A, etc.) refrigerants. 

Finalists in this category include: Daikin Applied Americas Inc., WMT; Innovair, DuoTec.


Winner: Airgreen

BMIL Brine-based DX Cold Room Heat Pump

The AirGreen-BMIL brine-based DX refrigerant system essentially creates a low dewpoint “heat pump” for cold room applications providing <26°F (3.3°C) dew-point supply air in a single process step. This packaged unit design provides up to 50% energy savings while also significantly reducing capital costs. It also eliminates the downtime related to multiple defrost cycles, or worse, downtime for cleaning if condensation forms. 

Finalists in this category include: Honeywell, Honeywell Solstice N71 (R-471A); Mitsubishi Electric Trane HVAC US, Mitsubishi Electric Variable Speed Scroll Compressors.


Winner: HVAC Manufacturing and Technology Inc.

SAV -  Smart Air Valve 

Innovation: The SAV-Smart Air Valve is an economical self-commissioning air control solution. It features a 100:1 turndown and precision airflow accuracy to within a few cfm operating as low .03” w.g. (74 Pa). It matches the ventilation rate to the risk of hazard featuring advanced demand control ventilation and low EUI with a single unit size. The SAV adds value and mitigates risk by creating a new simplified and economical value chain leading to a paradigm shift by making fixed orifice plate technology obsolete. The variable orifice plate technology solves a complex fluid dynamic problem of measuring a fluid accurately over a wide dynamic range, making current fixed orifice single venae contract fluid measurement/fluid control air terminals obsolete. It offers a variable dimensional aspect ratio footprint and solves current issues for end users, architects/engineers, contractors and TAB entities. 

Finalists in this category include: ECM PCB Stator Technology, High-Performance, Lightweight 12hp PCB Stator Blower Motor (Booth #S10334); LG Electronics U.S.A. Inc., LG Split Compact M3 DOAS with Multi V S.


Winner: Rheem Water Heating

Triton Light Duty (50- and 75-gallon)

Innovation: The Triton Light Duty (LD) high-efficiency commercial gas water heater from Rheem boasts built-in smart monitoring and precise leak detection. It prevents downtime, manages water heater issues and keeps businesses running smoothly. It is designed to promote energy efficiency and environmental responsibility and holds the potential to drive transformative changes in the way water heaters are conceptualized and manufactured. With a capacity ranging from 50 to 75 gallons (189 to 284 L), its patented combustion system and helical coil heat exchanger provide maximum thermal efficiency and durability.

Finalists in this category include: Bonomi North America, Inc., LOCPOWER Energy Harvesting Control Valves; ECM PCB Stator Technology, Ultra-light, Premium Efficiency 3HP PCB Stator Pump Solutions.
