B-Wheel Backward-Curved Modules Now With ErP 2015 Compliant 3.3-kW EC Motors

Award-winning Rosenberg B-Wheel backward curved fan modules are now available with ErP 2015 compliant 3.3 kW EC motors. The B-Wheel features a seven-blade design (instead of the standard eight) with a unique wheel geometry that provides for impeller efficiencies up to 78% while reducing noise by up to three dBA. It also increases airflow compared to standard impellers operating at the same speed.

The new B-Wheel modules are perfect for data center cooling applications and other demanding air-movement tasks with low noise and high efficiency requirements. The new modules are available in six sizes from 355-mm to 630-mm.

All Rosenberg fan motors are CE, UL and RoHS approved. Rosenberg EC motors are also ModBus compatible for easily networked system controls.

Rosenberg B-Wheel impellers feature all aluminum construction and robot-assisted welding. They are suitable for hygienic or outdoor applications without additional finishing or surface treatment.
