- IES5 efficiency reduces energy consumption by as much as 40% as compared to direct-on-line applications
- Seamless plug-and-play design simplifies installation
- Compact, lightweight build ideal for modern HVACR system
ABB, a global leader in HVACR motor and drive technologies, expanded its HVACR motor product line with the launch of ERH, a highly efficient, compact and lightweight solution for fan wall applications. This advanced motor technology delivers plug-and-play, variable-speed operation for simplified installation and lower energy consumption.
“Facility managers and OEMs face increasing pressure to cut operation costs, improve system performance and meet sustainability goals,” said Bevan Christiansen, ABB Global Segment Manager for Air Handling. “The ERH motor is our solution – a direct-drive motor that removes unnecessary components, minimizes energy waste and optimizes airflow efficiency.”
Traditional fan systems often require complex installation and frequent service and cause excessive energy use. ABB engineered ERH to address these challenges by eliminating belts, couplings and other wear components from the system, reducing mechanical stress while extending operational life. With IES5 efficiency, ERH cuts power costs while improving airflow control.
ERH’s variable-speed control allows precise adjustments, ensuring optimal ventilation while preventing wasted energy. The motor consumes as much as 40% less electricity than standard induction models run across the line which leads to substantial cost savings over its lifespan.
Unlike conventional units that demand extensive programming and commissioning, ERH comes pre-configured for immediate use, making setup quick and hassle-free. Its compact and lightweight build allows for easier integration into HVACR systems.
With an IP65-rated enclosure, ERH withstands demanding environments while maintaining efficiency and durability. Its exterior rotor flange mount provides a torque-dense, space-saving design. Built for long-term durability, ERH features sealed, greased-for-life bearings to reduce maintenance demands. Enhanced electrical discharge machining (EDM) protection prevents damage while ultra-quiet operation makes it ideal for noise-sensitive environments.
Designed and assembled in the United States, ERH supports a variety of air-handling applications, including data centers, hospitals and commercial and industrial buildings. ABB’s global service network provides ongoing support, offering OEMs and facility operators a future-ready solution that meets evolving industry standards.
