The new ZB 250 high-speed turbo blower provides wastewater aeration basins with high efficiency air. The new machine features a two-pole permanent magnet motor with rare earth element magnets.
Using an active magnet bearing, the ZB 250 offers maximum reliability. A dedicated bearing controller drives eight radial and two tangential bearing coils, enabling the rotor assembly to spin continually in its geometric center. In the event of a process upset, the bearing controller protects the machine by sensing the change in rotor position and automatically correcting it. If the machine experiences a surge, a shutdown is triggered.
“In over a decade of operation, we’ve never lost a machine from a bearing-related failure," said John Conover, business development manager - Americas blowers and low pressure compressors at Atlas Copco Compressors.
ZB packages come standard in a complete ‘ready-to-run’ trim level and are backed by Atlas Copco’s comprehensive field service guarantee.
