Series Vents Altivar Machine ATV320

APPLICATION

Altivar Machine ATV320 variable speed drives are designed to control fans with three-phase asynchronous motors rated from 0.37 to 22 kW.

They are used in general ventilation systems to regulate motor speed according to system parameters, which optimizes the operation of ventilation equipment and reduces energy consumption.

The ATV320 can also be used in pressurization systems to automatically maintain the required positive pressure in stairwells, airlocks, elevator shafts, and other protected areas.

Thanks to built-in safety functions, support for various control modes, and advanced configuration options, the ATV320 variable speed drives ensure reliable and efficient operation of ventilation equipment under various operating conditions.
