Infinitum Unveils Sustainable Heavy Duty Motor System at AHR 2025

Brings new levels of efficiency and sustainability to a wide range of heavy duty, mission critical HVAC applications

ORLANDO, Fla.--(BUSINESS WIRE)--Today at the AHR Expo, Infinitum, creator of the sustainable air-core motor, unveiled its Aircore Heavy Duty, a high-efficiency motor system designed to power the world’s most demanding, mission critical HVAC fan and pump applications with reduced energy consumption, emissions, noise and waste.

The Aircore Heavy Duty, which features an integrated variable frequency drive, sustainably powers heavy loads with up to 25% more efficiency, maximum power density and high-reliability. Its compact form factor is also 50% lighter and 60% shorter in length when compared to conventional motor and drive solutions.

Built with a rugged exterior for protection against dust, dirt and water, the Aircore Heavy Duty operates reliably in harsh outdoor or wet environments, maintaining high-efficiency over a wide range of operating points. Available immediately, it comes in a comprehensive range of power, bearing, NEMA MG1 shaft and frame sizes suitable for demanding, heavy duty applications, such as HVAC equipment, vertical-inline pumps, and Coolant Distribution Units (CDUs) used in data centers handling AI workloads, and in other mission critical facilities.

Additional features include:

• Rightsizing: Customers can specify a motor with the application's exact HP/RPM requirement, thereby reducing the power budget per motor; freeing up electrical infrastructure for other critical needs in the facility
• Communication: Supports a wide variety of communication protocols, including Modbus RTU, BACnet MSTP, Analog
• Controls: Enables users to configure and fine tune operational parameters, while monitoring motor performance, carbon emissions, energy consumption, heat and vibration;
• Serviceability: Modular design makes repairs fast and simple
• Flexible Mounting: Compact form factor optimizes space, reduces wiring needs and facilitates direct mounting to pump applications, increasing efficiency by 10-15%.

Like other Infinitum motors, the Aircore Heavy Duty motor replaces the copper wound iron stator found in traditional motors with a lightweight, printed circuit board (PCB) stator that is 10x more reliable. The motor uses 66% less copper and no iron in the stator, and produces significantly less noise. Infinitum’s motors are manufactured in a sustainable facility from components that can be remanufactured and reused so they stay in service and out of landfills.

“With its newest Aircore Heavy Duty model, Infinitum is continuing to serve the larger sustainability picture. The motor appears well suited to improve overall system efficiency while addressing broader electrical infrastructure concerns. In my opinion, this motor is poised to help customers improve on sustainability, usability, and the bottom line,” said Blake Griffin, Interact Analysis.

“Our new Aircore Heavy Duty brings our award-winning motor system design to the world’s highest-emitting HVAC fan and pump applications, including those that are increasingly used to cool data centers handling AI workloads,” said Ben Schuler, founder and CEO of Infinitum. “Our talented team has once again raised the bar for efficiency, serviceability and reliability to power the world with less energy, material and waste.”
